Abstract:

This study explores the interplay between Classical Mechanics, Relativistic Lorentz Transformation, and Extended Classical Mechanics (ECM) to provide a comprehensive perspective on kinetic energy, effective mass, and time distortion. Traditional interpretations of relativity overlook the role of acceleration and force-induced deformations, particularly in the context of mass-energy redistribution. By integrating Hooke’s Law into motion mechanics, this work demonstrates that effective mass (mᵉᶠᶠ)—often misinterpreted as relativistic mass—is a result of potential energy conversion rather than an intrinsic increase in inertial mass.

Furthermore, this study challenges relativistic length contraction by showing that deformation under force provides a more consistent physical explanation than velocity-based transformations. A phase shift approach to time distortion is introduced, linking oscillator deformation with observable time variations, providing an alternative to abstract spacetime interpretations.

By bridging classical and relativistic mechanics through ECM, this study proposes a physically grounded framework for understanding motion, energy interactions, and time effects, offering an empirically testable alternative to conventional relativity.

Introduction:

Classical mechanics has long provided a foundational framework for understanding motion, forces, and energy interactions. However, traditional interpretations of relativistic effects often overlook the role of acceleration and force-induced deformations when addressing length contraction and time dilation. The relativistic Lorentz transformation describes time and space alterations due to velocity but does not explicitly account for the underlying mechanical forces responsible for these transformations. This omission raises fundamental questions about the physical origin of mass deformation, relativistic mass variation, and time distortion.

This paper explores the connection between classical mechanics, relativistic Lorentz transformations, and the emerging framework of Extended Classical Mechanics (ECM). By integrating force-based considerations—particularly Hooke’s Law and mechanical deformations—this study offers an alternative interpretation of kinetic energy, effective mass, and time distortion. The concept of effective mass (mᵉᶠᶠ) is re-examined in relation to energy redistribution, demonstrating how its reduction during motion is linked to potential energy loss rather than an abstract relativistic mass increase.

Furthermore, a phase shift-based approach to time distortion is introduced, emphasizing how force-induced material deformations influence oscillator frequencies, leading to measurable time variations. By revisiting these principles through the lens of ECM, this work challenges conventional relativistic assumptions and provides a physically consistent mechanism for understanding motion, energy distribution, and time distortion beyond traditional interpretations.

1. Kinetic Energy and Effective Mass in Classical Mechanics

In classical mechanics, kinetic energy represents an effective mass (mᵉᶠᶠ) when an inertial mass (m) is in motion or subject to a gravitational potential difference, where mᵉᶠᶠ<m.

When two inertial reference frames initially share the same motion and direction relative to each other, they are indistinguishable in their observations of physical phenomena. However, if these frames separate in the same direction, they must acquire different velocities. This necessity of velocity change highlights the role of acceleration in achieving their separation.

Despite acceleration being fundamental to transitioning between different inertial reference frames, it is not explicitly considered in the Lorentz factor or relativity, even though it plays a crucial role in transitioning from v₀ to v₁. This raises important questions about its implications in both classical mechanics and relativistic Lorentz transformations.

During the formulation of the Lorentz factor:

γ = √(1 - v/c)²

or relativistic time dilation:

Δt′ = t₀/√(1 - v/c)² 

it was acknowledged that Newton’s second law:

F = ma

induces a force (F) that influences velocity-dependent relativistic transformations. This force leads to deformations in moving objects, affecting relativistic mass, length contraction, and time dilation.

For example, Hooke’s Law:

F = kΔL

describes such deformations, suggesting that Lorentz transformations incorporate force-induced structural changes that impact the effective mass of an object.

2. Energy and Effective Mass in Motion

In classical mechanics, the total energy (E) of a system is defined as:

E = PE + KE

Potential Energy When v = 0:

When an object is at rest, all of its energy is stored as potential energy:

Eₜₒₜₐₗ = PE

which means the total mass equivalent remains simply m.

Energy Distribution When v > 0:

Once an object gains velocity, part of its potential energy is converted into kinetic energy:

PE − ΔPE = PE + KE

The change in potential energy (ΔPE) appears as kinetic energy:

KE = −ΔPE

Effective Mass Contribution:

Since kinetic energy arises from potential energy loss, the effective mass associated with kinetic energy follows:

|mᵉᶠᶠ| = −ΔPE

This ensures that total energy remains balanced, with kinetic energy representing a redistributed form of the system’s original mass-energy.

Given that potential energy (PE) corresponds to the inertial mass (m), and kinetic energy (KE) is linked to an effective mass (|mᵉᶠᶠ|), we express the force equation as:

F = |mᵉᶠᶠ|a

where the effective mass accounts for both the deformation-induced contribution from stiffness (k) and the inertial mass (m):

|mᵉᶠᶠ| = |kΔL|/a

Substituting this into the force equation:

F = (|kΔL|/a)⋅a

Expanding into the energy relation:

E = PE + KE ⇒ m + |mᵉᶠᶠ|

Since mᵉᶠᶠ contributes to balancing total energy, the correct formulation becomes:

E = m + |kΔL|/a

where kinetic energy is directly linked to effective mass (|mᵉᶠᶠ|), sometimes misinterpreted as relativistic mass (m′) and associated with time distortion (Δt′) in certain contexts.

3. Phase Shift and Time Distortion

A relevant analogy is piezoelectric materials, which convert mechanical energy into electrical energy. The phase shift in oscillations plays a key role in this conversion, influencing timing and energy distribution.

This relationship is described by:

Δt′ = (x°/f)/360

 

where x∘ is the phase shift in degrees and f is the original oscillation frequency. In piezoelectric materials, mechanical force alters phase oscillations, affecting energy conversion timing.

Since electromagnetic oscillations (and mechanical oscillations) are sensitive to force-induced deformations, phase shifts manifest as time distortions. This provides a direct method for calculating time dilation from phase measurements, challenging conventional relativistic interpretations by providing a tangible, testable mechanism for time distortion.

4. Clarification on the Sign of mᵉᶠᶠ in Classical Mechanics

In classical mechanics, where antigravity, negative mass, or negative apparent mass are not explicitly considered, the effective mass (mᵉᶠᶠ) is always positive but less than the original inertial mass (m) when a system is in motion or subjected to a gravitational potential difference. This reduction in mᵉᶠᶠ results from energy redistribution due to the force involved in motion, altering the inertial response of the system. However, classical mechanics does not recognize an invisible energetic counterpart that counteracts this apparent reduction in mass.

Unlike ECM, which incorporates matter mass (Mᴍ) as a combination of ordinary matter (Mᴏʀᴅ) and dark matter mass (Mᴅᴍ), along with negative apparent mass (−Mᵃᵖᵖ), classical mechanics attributes the decrease in effective mass solely to energy partitioning, without interpreting it as a fundamental negative mass effect.

The reason mᵉᶠᶠ remains strictly positive in classical mechanics is that mass is only considered to diminish in response to dynamics but never becomes negative or assumes an imperceptible energetic form as in ECM. Instead, classical mechanics treats mᵉᶠᶠ as a dynamically altered but always positive quantity, reflecting only the redistribution of the system’s energy.

This distinction is crucial for ensuring that classical mechanics remains consistent with Newtonian principles, while ECM extends beyond these boundaries to incorporate mass-energy interactions at deeper levels.

5. Justification for Hooke’s Law in Motion Over Relativistic Length Contraction

Hooke’s Law provides a more consistent description of mass deformation (ΔL) than relativistic length contraction (L′), which is traditionally derived from velocity-based transformations.

Key Issues with Relativistic Length Contraction:

1. Assumes purely velocity-dependent deformation: Ignores material stiffness.

2. Linear object assumption: Emphasizes length deformation but ignores cubic volume changes.

3. Neglects acceleration effects: Does not explicitly account for transition from rest to motion.

Advantages of Hooke’s Law in Motion:

• Applies across all speed ranges, including low speeds where relativistic effects are negligible.

• Includes acceleration, whereas relativistic transformations assume undeclared competition with deformation mechanics.

Since relativistic length contraction lacks a robust material-based justification, Hooke’s Law provides a more physically grounded approach to deformation across all force conditions. This suggests that relativistic transformations should be reconsidered as force-induced mechanical responses rather than purely geometric effects.

6. Final Considerations on Force, Deformation, and Time Distortion

All clocks—mechanical, electronic, or atomic—are composed of materials that undergo deformation under external forces. These deformations alter oscillator frequencies, leading to shifts in oscillation cycles.

When an external force deforms the oscillator material, the frequency changes, creating a phase shift expressed as:

Δt′ = (x°/f)/360

 

This empirical relationship provides a direct link between force-induced deformations and time distortions, making the effect verifiable through phase measurements. This interpretation challenges traditional relativistic notions by presenting time dilation as a tangible material response rather than an abstract spacetime transformation.

Abstract:

This study explores the mathematical coherence of Extended Classical Mechanics (ECM) in describing mass-energy transformations and gravitational interactions. It establishes a refined mass-energy equivalence by incorporating negative apparent mass (−Mᵃᵖᵖ) as a kinetic energy counterpart, ensuring dynamic conservation laws. The ECM force equation is analysed to demonstrate how effective mass (Mᵉᶠᶠ) varies with motion, aligning with classical mechanics and gravitational effects. Additionally, ECM’s modified gravitational equation is compared with A. D. Chernin et al.'s framework, revealing that dark energy (Mᴅᴇ) can be interpreted as ECM’s negative apparent mass (−Mᵃᵖᵖ). This approach provides a natural explanation for dark energy effects in large-scale structures, suggesting an emergent gravitational phenomenon rather than an external vacuum energy component. The alignment between ECM and the Coma cluster equation further supports ECM's capacity to integrate dark energy within a modified gravitational framework, offering a coherent alternative to the ΛCDM model.

Keywords:

Extended Classical Mechanics (ECM), mass-energy equivalence, negative apparent mass, gravitational interactions, kinetic energy transformation, dark energy, effective mass, modified gravitational equation, cosmic acceleration, Coma cluster equation.

Mathematical Consistency of ECM Mass-Energy Dynamics:

When a system with stored potential energy (PE) undergoes energy transformation, a portion of its stored energy is converted into motion, represented as kinetic energy (KE). Initially, all energy is in the form of stored potential energy:

Eₜₒₜₐₗ = PE

As the system moves, a portion of this stored energy ΔPE is transferred into kinetic energy:

KE = ΔPE

This reduces the remaining stored energy to PE−ΔPE, ensuring that energy is conserved:

Eₜₒₜₐₗ = (PE−ΔPE) + ΔPE = PE

Thus, the redistribution between stored and motion energy follows:

PE ∝ 1/KE = 1/ΔPE

which maintains dynamic equilibrium in the system.

Acceleration and Dynamic Mass Relation in Classical Mechanics:

In Classical Mechanics, acceleration follows the inverse-mass relation:

F = ma, where a ∝ 1/m

​Since force is proportional to acceleration, we obtain:

F ∝ a ∝ 1/m

This implies that force interacts dynamically with acceleration, reinforcing the concept that mass inversely influences motion.

Potential Energy and Dynamic Mass Equivalence:

When a system undergoes motion, its potential mass (m) contributes to kinetic energy, leading to a mass-energy relationship:

• Potential Mass: m ⇐ PE 

• Kinetic Mass: 1/m ⇐ KE

From the total energy equation:

Eₜₒₜₐₗ = PE + KE

At rest (KE=0), the total energy remains purely potential:

Eₜₒₜₐₗ =PE

As kinetic energy increases, a portion of potential energy (ΔPE) converts into motion:

Eₜₒₜₐₗ = (PE−ΔPE) + ΔPE

This ensures that energy is dynamically conserved, with mass playing a key role in its redistribution.

Mass-Energy Equivalence in ECM:

In ECM, mass-energy transformations follow a refined approach. The classical mass-energy conversion:

Eₜₒₜₐₗ = (PE−ΔPE) + ΔPE

can be rewritten in ECM by incorporating mass-energy equivalence:

Eₜₒₜₐₗ = (m−Δm) + 1/Δm

where negative apparent mass (−Mᵃᵖᵖ) emerges as part of the kinetic energy contribution:

−Mᵃᵖᵖ ⇐ −Δm

Thus, in ECM, the kinetic energy term is inherently linked to negative apparent mass, maintaining dynamic energy balance.

Physical Coherence of Negative Apparent Mass in ECM:

The introduction of negative apparent mass (−Mᵃᵖᵖ) as a kinetic energy counterpart aligns with ECM's principle that effective mass shifts dynamically during motion. The ECM force equation:

Fᴇᴄᴍ = Mᵉᶠᶠaᵉᶠᶠ, where Mᵉᶠᶠ = Mᴍ −Mᵃᵖᵖ

Since −Δm represents the dynamic negative mass component transferred to kinetic energy, defining:

−Δm⇒ −Mᵃᵖᵖ

is a natural extension of ECM's mass-energy framework. The total energy remains balanced:

Eₜₒₜₐₗ = (PE−ΔPE) + ΔPE

where the loss in potential energy (PE−ΔPE) corresponds exactly to the gain in kinetic energy (ΔPE), ensuring strict adherence to conservation laws:

ΔPE − ΔPE = 0

Thus, the mass-energy transformation follows:

−Mᵃᵖᵖ = Δm

confirming the dynamic role of negative apparent mass in ECM.

Extended Classical Mechanics (ECM)’s Modified Gravitational Equation:

ECM modifies the gravitational equation as:

Mɢ = Mᴍ + (−Mᵃᵖᵖ)

where:

• Mᴍ = Matter mass (sum of ordinary matter and dark matter: Mᴏʀᴅ + Mᴅᴇ).

• −Mᵃᵖᵖ = Apparent mass, associated with antigravity effects (dark energy in ECM terms).

• Mᵉᶠᶠ = Mᴍ + (-Mᵃᵖᵖ) = Effective mass that determines the net gravitational behaviour.

A key ECM condition is:

• Within gravitational influence (|Mᴍ| > |−Mᵃᵖᵖ|) → Mᵉᶠᶠ > 0, leading to gravitational attraction.

• Beyond gravitational influence (|Mᴍ| < |−Mᵃᵖᵖ|) → Mᵉᶠᶠ < 0, leading to antigravity effects (dark energy dominance).

Alignment Between ECM and Chernin et al.’s Model:

(a) Gravitational Mass Equivalence

A. D. Chernin et al. define the gravitational mass as:

Mɢ = Mᴍ + Mᴅᴇ

ECM defines it as:

Mɢ = Mᴍ + (−Mᵃᵖᵖ)

which means that in ECM:

−Mᵃᵖᵖ ≡ Mᴅᴇ

showing that ECM's apparent mass (−Mᵃᵖᵖ) plays the role of dark energy's effective mass (Mᴅᴇ) in A. D. Chernin et al.'s framework.

This suggests that ECM naturally integrates dark energy as a negative apparent mass, influencing large-scale gravitational interactions.

(b) Dark Energy Dominance Beyond Gravitational Influence

In A. D. Chernin et al.’s work:

• For R < Rᴢɢ, gravity dominates, meaning Mɢ ≈ Mᴍ.

• For R > Rᴢɢ, dark energy dominates, leading to Mɢ < 0.

In ECM:

• For |Mᴍ| > |−Mᵃᵖᵖ|, effective mass remains positive (gravitational attraction).

• For |Mᴍ| < |−Mᵃᵖᵖ|, effective mass turns negative (antigravity/acceleration).

This aligns with A. D. Chernin et al.'s finding that beyond the zero-gravity radius, dark energy overcomes matter’s gravitational influence.

ECM’s Apparent Mass (−Mᵃᵖᵖ) and Dark Energy (Mᴅᴇ):

• In ECM, apparent mass (−Mᵃᵖᵖ) is responsible for the observed effects of dark energy.

• When Mᵉᶠᶠ < 0 (i.e., when apparent mass dominates), the system is in an antigravity regime, consistent with dark energy's effects.

This suggests a fundamental insight:

• ECM describes dark energy not as an external vacuum energy but as an emergent gravitational phenomenon related to mass oscillations and effective mass balance.

• Instead of treating dark energy as a fluid with negative pressure, ECM sees it as a result of apparent mass effects, which naturally emerge when gravitational mass becomes negative beyond a critical scale.

Conclusion

Chernin et al.’s research provides a compelling argument that dark energy modifies the structure of galaxy clusters. ECM offers a refined interpretation, suggesting that dark energy is not a mysterious external force but rather an emergent effect of apparent mass (−Mᵃᵖᵖ).

By equating Mᴅᴇ with −Mᵃᵖᵖ, ECM naturally explains why dark energy behaves as negative mass in large-scale structures, eliminating the need for an unknown energy component. This alignment suggests that gravitational mass (Mɢ) in ECM is the key to understanding cosmic acceleration without requiring a vacuum energy density interpretation.

ECM’s Modified Gravitational Equation vs. Coma Cluster Equation:

ECM’s gravitational equation is given by:

Mɢ = Mᴍ + (−Mᵃᵖᵖ)

where

• Mᴍ = Mᴏʀᴅ + Mᴅᴇ represents the total matter mass (ordinary + dark matter).

• −Mᵃᵖᵖ represents the apparent mass, which emerges from gravitational interactions and contributes to anti-gravitational effects.

• Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ) is the effective mass governing motion.

Now, in the equation used in the study of the Coma cluster:

Mɢ = Mᴍ + Mᴅᴇ

where

• Mᴍ = Mᴏʀᴅ + Mᴅᴇ, which is similar to ECM’s matter mass term.

• Mᴅᴇ represents the contribution of dark energy to the system.

Alignment with ECM:

• When gravitational influence dominates, we have ∣Mᴍ∣ > ∣−Mᵃᵖᵖ∣, meaning that matter mass (Mᴍ) is the leading factor, keeping the net effective mass positive (Mᵉᶠᶠ >0).

• However, when dark energy dominates at cosmic scales beyond gravitational influence, the apparent mass −Mᵃᵖᵖ grows such that ∣−Mᵃᵖᵖ∣ > ∣Mᴍ∣, making Mᵉᶠᶠ negative.

In this regime, ECM predicts:

Mᵉᶠᶠ = Mᴅᴇ, when ∣−Mᵃᵖᵖ∣ > ∣Mᴍ∣  

which mirrors the Coma cluster equation by associating the negative effective mass of ECM with the dominant contribution of dark energy.

Apparent Mass (-Mᵃᵖᵖ) as Mᴅᴇ in a Dark Energy-Dominated Regime:

In ECM, apparent mass −Mᵃᵖᵖ emerges as a result of gravitational interactions and can take on values that counterbalance or even exceed the total matter mass Mᴍ.

• When ∣Mᴍ∣ > ∣−Mᵃᵖᵖ∣, the effective mass becomes negative (Mᵉᶠᶠ <0), signifying that the system has transitioned into a regime dominated by anti-gravity or dark energy-like effects.

• In this scenario, ECM predicts that the negative apparent mass is equivalent to the dark energy mass contribution:

−Mᵃᵖᵖ  =  Mᴅᴇ

This establishes that beyond gravitationally bound systems, apparent mass in ECM behaves like dark energy, driving expansion due to its repulsive nature.

Conclusion

• ECM’s modified gravitational equation naturally extends the structure of the Coma cluster equation by incorporating apparent mass, which accounts for dark energy effects dynamically.

• ECM’s apparent mass (−Mᵃᵖᵖ) represents the contribution of dark energy when gravitational mass (Mᴍ) is small compared to anti-gravitational effects, leading to an effective mass that aligns with the Coma cluster interpretation of dark energy.

Thus, ECM provides a clear mechanical basis for the transition between gravitationally bound and dark energy-dominated regions, linking gravitational mass, apparent mass, and effective mass in a unified framework.

Derivation and Scientific Consistency of Apparent Mass (−Mᵃᵖᵖ) in Extended Classical Mechanics (ECM):

To fully establish the physical validity and consistency of apparent mass (−Mᵃᵖᵖ) in ECM, we will systematically derive it and verify its scientific coherence on two key counts:

1. Physical Coherence of Negative Apparent Mass in ECM.

2. Apparent Mass (-Mᵃᵖᵖ) as Mᴅᴇ in a Dark Energy-Dominated Regime.

Derivation of Apparent Mass (−Mᵃᵖᵖ) in ECM:

ECM refines gravitational mass Mɢ by incorporating apparent mass as follows:

Mɢ = Mᴍ + (−Mᵃᵖᵖ)

where:

• Mᴍ = Mᴏʀᴅ + Mᴅᴇ is the total matter mass (ordinary + dark matter).

• −Mᵃᵖᵖ is the apparent mass emerging due to gravitational interaction effects.

• The effective mass, governing motion, is:

Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ).

Step 1: How Apparent Mass Emerges from Mass Reduction Effects:

• Classical mechanics defines force as F = ma, meaning mass contributes to force generation.

• In ECM, acceleration affects mass perception, leading to a scenario where a portion of mass becomes imperceptible due to gravitational effects, manifesting as an apparent reduction of mass.

• This means that under high-energy conditions (such as gravitational collapse or accelerated motion at cosmic scales), some mass shifts from positive to apparent negative mass −Mᵃᵖᵖ), which counterbalances Mᴍ in certain conditions.

Step 2: Effective Mass and the Role of Apparent Mass

• In a gravitationally bound system, matter mass dominates:

∣Mᴍ∣ > ∣−Mᵃᵖᵖ∣ ⇒ Mᵉᶠᶠ > 0

This means the system behaves as expected under Newtonian-like gravity.

• However, beyond gravitational influence, apparent mass grows, counteracting normal mass:

∣−Mᵃᵖᵖ∣ > ∣Mᴍ∣ ⇒ Mᵉᶠᶠ < 0

Here, negative effective mass emerges, leading to repulsive gravity, which is a fundamental characteristic of dark energy-driven cosmic acceleration.

Scientific Consistency of Apparent Mass (−Mᵃᵖᵖ):

Now, let’s establish the scientific validity of apparent mass (−Mᵃᵖᵖ) on two critical counts:

Physical Coherence of Negative Apparent Mass in ECM:

Negative apparent mass (−Mᵃᵖᵖ) is scientifically coherent because:

• (a) It Emerges from Classical Mechanics Principles

• Apparent mass behaves like an inertia-modified term, consistent with mass-energy interactions.

• It aligns with Newton's laws but introduces an emergent term (−Mᵃᵖᵖ), explaining effects not covered by classical mechanics alone.

• (b) It Resolves Gravitational Mass Anomalies

• Classical gravity struggles to explain mass deficits in galactic clusters.

• ECM’s approach naturally accounts for apparent mass, leading to self-consistent gravitational calculations.

• (c) It Provides a Logical Explanation for Acceleration-Induced Mass Effects

• Standard models treat mass as a static quantity.

• ECM allows mass to vary under acceleration/gravitational interactions, producing apparent negative mass under extreme conditions.

• (d) It Refines the Concept of Force and Motion

• The ECM force equation:

Fᴇᴄᴍ = (Mᴍ + (−Mᵃᵖᵖ))aᵉᶠᶠ 

explicitly integrates apparent mass, showing its direct role in dynamics.

Apparent Mass (−Mᵃᵖᵖ) as Mᴅᴇ in a Dark Energy-Dominated Regime:

• (a) When Gravitational Influence Weakens, −Mᵃᵖᵖ Becomes Dominant

• Beyond local gravitational binding, the negative apparent mass (−Mᵃᵖᵖ) increases in magnitude.

• This mimics the behaviour of dark energy, which dominates cosmic expansion.

• (b) Consistency with Observations of Dark Energy Effects

• Observations show accelerated cosmic expansion.

• ECM predicts that when:

∣Mᴍ∣ < ∣−Mᵃᵖᵖ∣ ⇒ Mᵉᶠᶠ = −Mᵃᵖᵖ ≈ Mᴅᴇ

meaning that negative apparent mass directly accounts for dark energy.

• (c) How This Aligns with the Coma Cluster Equation

• In the Coma cluster mass model:

Mɢ = Mᴍ + Mᴅᴇ

• ECM provides an equivalent interpretation:

Mɢ = Mᴍ + (−Mᵃᵖᵖ)

• Thus, ECM naturally interprets dark energy as a form of negative apparent mass!

Summary of Key Findings:

Derivation of Apparent Mass

• Apparent mass (−Mᵃᵖᵖ) emerges from mass reduction effects in gravitational interactions.

• It leads to negative effective mass when it dominates over normal matter mass.

Scientific Coherence of −Mᵃᵖᵖ

• It is consistent with classical mechanics principles when extended to variable mass effects.

• It explains gravitational anomalies and aligns with observed cosmic acceleration.

−Mᵃᵖᵖ as a Dark Energy Equivalent:

• When beyond gravitational influences, −Mᵃᵖᵖ behaves like dark energy (Mᴅᴇ).

• This provides a natural explanation for the accelerated expansion of the universe.

Thus, ECM’s apparent mass concept is not only logically sound but also bridges classical mechanics with modern cosmological observations. 

Consistency of Effective Mass and Gravitating Mass in an Extended Classical Mechanics System:

February 04, 2025

In a system:

The effective mass (Mᵉᶠᶠ) is defined as the sum of the matter mass (Mᴍ) and the negative apparent mass (−Mᵃᵖᵖ). The matter mass itself consists of the ordinary matter mass (Mᴏʀᴅ) and the mass of dark matter (Mᴅᴍ). Consequently, the effective mass is equivalent to the gravitating mass (Mɢ).

The effective mass remains positive (Mᵉᶠᶠ>0) when the absolute magnitude of the matter mass |Mᴍ| exceeds the absolute magnitude of the negative apparent mass |−Mᵃᵖᵖ|. Conversely, the effective mass becomes negative (Mᵉᶠᶠ<0) when the absolute magnitude of the matter mass is less than the absolute magnitude of the negative apparent mass.

Similarly, the gravitating mass follows the same conditions as the effective mass, remaining positive (Mɢ>0) when the absolute magnitude of the matter mass is greater than the absolute magnitude of the negative apparent mass and becoming negative (Mɢ<0) when the absolute magnitude of the matter mass is smaller than the absolute magnitude of the negative apparent mass.

Additionally, the negative apparent mass can be expressed as the difference between the matter mass and the effective mass. Since the effective mass is equivalent to the gravitating mass, the negative apparent mass can also be described as the difference between the matter mass and the gravitating mass.

In ECM Systems:

Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ), where Mᴍ = Mᴏʀᴅ + Mᴅᴍ

Therefore,  Mᵉᶠᶠ = Mɢ 

And the relationships are:

Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ), where Mᵉᶠᶠ > 0 

when |Mᴍ| > |−Mᵃᵖᵖ| and Mᵉᶠᶠ < 0 when |Mᴍ| < |−Mᵃᵖᵖ|

Mɢ = Mᴍ + (−Mᵃᵖᵖ), where Mɢ > 0 

when |Mᴍ| > |−Mᵃᵖᵖ| and Mɢ < 0 when |Mᴍ| < |−Mᵃᵖᵖ|

Mᵃᵖᵖ = Mᴍ − Mᵉᶠᶠ

Mᵃᵖᵖ = Mᴍ − Mɢ

Mass-Energy Dynamics in Extended Classical Mechanics (ECM)

Soumendra Nath Thakur

March 04, 2025

In Classical Mechanics, when kinetic energy is zero (KE=0), the total energy of the system is entirely in the form of potential energy (Eₜₒₜₐₗ = PE), which is associated with the rest mass (m) of the object.

When a force (F) is applied to the object, it accelerates, resulting in an increase in kinetic energy (KE). The total energy of the system is then the sum of potential and kinetic energy:

Eₜₒₜₐₗ = PE + KE

During energy transformation, a portion of the stored energy (PE) is converted into kinetic energy (KE). This transformation can be expressed as:

KE  = ΔPE, so that Eₜₒₜₐₗ = (PE − ΔPE) + ΔPE 

Initially, all of the system's energy is in the form of stored energy (PE). As the system moves, part of this energy is used to generate motion, reducing the stored energy to PE−ΔPE, while the extracted portion becomes kinetic energy (KE=ΔPE).

Despite this redistribution, the total energy remains unchanged; only its allocation between stored energy and motion energy shifts. This balance is maintained by the inverse relationship:

PE ∝ 1/KE = 1/ΔPE

Thus, any reduction in stored energy results in an equal increase in kinetic energy, ensuring conservation within the system.

Potential Energy, Kinetic Energy, and Mass Relation in ECM:

In ECM, an object's energy is dynamically linked to its motion and gravitational interactions. The relationship between potential energy (PE), kinetic energy (KE), and mass follows an inverse relation, where:

PE ∝ 1/KE = 1/ΔPE

Total Energy at Rest and in Motion:

At rest, the total energy of an object with mass m is entirely in the form of potential energy:

Eₜₒₜₐₗ = PE

When a force is applied, the object undergoes acceleration, leading to a conversion of stored potential energy (PE) into kinetic energy (KE). The total energy expression becomes:

Eₜₒₜₐₗ = PE + KE = (PE − ΔPE) + (ΔPE) 

where ΔPE is the portion of potential energy converted into kinetic energy.

Dynamic Mass Response and Force Relation:

Applying Newton’s second law (F=ma):

Since acceleration is inversely proportional to mass (a∝1/m), increasing acceleration leads to an apparent reduction in effective mass.

This means that as the system gains kinetic energy (KE=ΔPE), the object’s potential energy decreases (PE−ΔPE), and the apparent mass contribution emerges

Apparent Mass and Effective Mass in ECM:

Since kinetic energy is dynamically linked to mass, the corresponding mass equivalent of KE is negative apparent mass:

KE = ∣ΔPE∣ corresponds −Mᵃᵖᵖ = ∣ΔPE∣ 

Since apparent mass is inherently negative, the formulation remains valid without further sign corrections.

Thus, the ECM mass-energy relation is given by:

Eₜₒₜₐₗ,ᴇᴄᴍ = (Mᴍ − Mᵃᵖᵖ) + (−Mᵃᵖᵖ)

which simplifies to:

Eₜₒₜₐₗ,ᴇᴄᴍ = ±Mᵉᶠᶠ + (−Mᵃᵖᵖ)

where:

• Mᴍ is the matter mass,

• −Mᵃᵖᵖ represents the negative apparent mass contribution arising from kinetic energy,

• Mᵉᶠᶠ represents the effective mass, which adjusts dynamically with motion.

Key Interpretation in ECM:

•  Mass is not an intrinsic property but a dynamic response to motion and gravitational interactions.

•  Acceleration reduces the contribution of effective mass, increasing kinetic energy and manifesting as negative apparent mass.

•  The total energy balance remains consistent, with kinetic energy linked to an inverse mass-energy relation.

Mathematical Consistency of ECM Mass-Energy Dynamics:

March 04, 2025

Force Equation In Classical Mechanics  (Motion):

F = ma

Acceleration follows the classical inverse-mass relation:

a ∝ 1/m

​Since force is proportional to acceleration, this implies:

F ∝ a ∝ 1/m

which suggests that force arcs dynamically with acceleration.

Potential Energy and Dynamic Mass Relation:

When a system undergoes motion, the potential mass m generates kinetic energy, leading to a mass-energy equivalence in dynamic motion:

Potential Energy (PE ⇒ m), Kinetic energy (KE ⇒ 1/m)

This follows from the total energy equation:

Eₜₒₜₐₗ = PE + KE where PE ⇒ m, KE ⇒ 1/m

At rest, kinetic energy is zero, so:

Eₜₒₜₐₗ = PE, when KE = 0

As kinetic energy increases, a portion of the potential energy ΔPE converts into kinetic energy:

Eₜₒₜₐₗ = PE + KE = (PE − ΔPE) + ΔPE

Substituting mass-energy equivalence in ECM, we write:

Eₜₒₜₐₗ  = (m − Δm) + 1/Δm

​Since negative apparent mass (−Mᵃᵖᵖ) arises from the kinetic energy contribution, we identify:

−Δm ⇒ −Mᵃᵖᵖ

Thus, the negative apparent mass corresponds to the kinetic energy term in ECM, balancing the total energy equation dynamically.

Physical Coherence of −Mᵃᵖᵖ

The introduction of negative apparent mass (−Mᵃᵖᵖ) as arising from kinetic energy is consistent with ECM's premise that kinetic energy contributes to an effective mass shift.

Since −Δm represents the mass component transferred to kinetic energy, defining −Δm ⇒ −Mᵃᵖᵖ is reasonable under ECM.

Eₜₒₜₐₗ = PE + ΔPE = (PE − ΔPE) + ΔPE, where PE = (PE − ΔPE) and KE  = ΔPE

When a system (PE) undergoes energy transformation, some of its stored energy (PE − ΔPE) is converted into motion KE  = ΔPE. 

Initially, all of the system's energy is in the form of stored energy (PE). As the system moves, a portion of this stored energy is used to generate movement, reducing the amount that remains stored (PE − ΔPE). 

The part that is taken from storage becomes energy associated with motion 

KE  = ΔPE. 

However, the total energy of the system Eₜₒₜₐₗ = PE + ΔPE = (PE − ΔPE) + ΔPE does not change—only the way it is distributed between stored energy PE and motion energy KE  (=ΔPE) shifts. 

This ensures that any reduction in stored energy results in an equal increase in motion energy PE ∝ 1/KE = 1/ΔPE , maintaining balance in the system.

Consistency of Effective Mass and Gravitating Mass in an Extended Classical Mechanics System:

In a system:

The effective mass (Mᵉᶠᶠ) is defined as the sum of the matter mass (Mᴍ) and the negative apparent mass (−Mᵃᵖᵖ). The matter mass itself consists of the ordinary matter mass (Mᴏʀᴅ) and the mass of dark matter (Mᴅᴍ). Consequently, the effective mass is equivalent to the gravitating mass (Mɢ).

The effective mass remains positive (Mᵉᶠᶠ>0) when the absolute magnitude of the matter mass |Mᴍ| exceeds the absolute magnitude of the negative apparent mass |−Mᵃᵖᵖ|. Conversely, the effective mass becomes negative (Mᵉᶠᶠ<0) when the absolute magnitude of the matter mass is less than the absolute magnitude of the negative apparent mass.

Similarly, the gravitating mass follows the same conditions as the effective mass, remaining positive (Mɢ>0) when the absolute magnitude of the matter mass is greater than the absolute magnitude of the negative apparent mass and becoming negative (Mɢ<0) when the absolute magnitude of the matter mass is smaller than the absolute magnitude of the negative apparent mass.

Additionally, the negative apparent mass can be expressed as the difference between the matter mass and the effective mass. Since the effective mass is equivalent to the gravitating mass, the negative apparent mass can also be described as the difference between the matter mass and the gravitating mass.

In a system:

The effective mass (Mᵉᶠᶠ) is defined as the sum of the matter mass (Mᴍ) and the negative apparent mass (−Mᵃᵖᵖ). The matter mass consists of the ordinary matter mass (Mᴏʀᴅ) and the mass of dark matter (Mᴅᴍ), so that:

Mᴍ = Mᴏʀᴅ + Mᴅᴍ

Since the effective mass is derived from the matter mass and negative apparent mass, it is equivalent to the gravitating mass (Mɢ), meaning:

Mᵉᶠᶠ = Mᴍ + (−Mᵃᵖᵖ) = Mɢ

The sign of the effective mass depends on the relative magnitudes of the matter mass and the negative apparent mass. Specifically:

• The effective mass remains positive (Mᵉᶠᶠ > 0) when the absolute magnitude of the matter mass |Mᴍ| is greater than the absolute magnitude of the negative apparent mass |−Mᵃᵖᵖ|.
• Conversely, the effective mass becomes negative (Mᵉᶠᶠ < 0) when the absolute magnitude of the matter mass is smaller than the absolute magnitude of the negative apparent mass.

Since the gravitating mass follows the same fundamental equation as the effective mass, it exhibits the same conditions:

• The gravitating mass remains positive (Mɢ > 0) when |Mᴍ| > |−Mᵃᵖᵖ|.
• The gravitating mass becomes negative (Mɢ < 0) when |Mᴍ| < |−Mᵃᵖᵖ|.

Additionally, the negative apparent mass (−Mᵃᵖᵖ) can be expressed as the difference between the matter mass and the effective mass:

Mᵃᵖᵖ = Mᴍ − Mᵉᶠᶠ

Since the effective mass is equal to the gravitating mass, this also means:

Mᵃᵖᵖ = Mᴍ − Mɢ
