Abstract
This
chapter establishes the foundation of Extended Classical Mechanics
(ECM) by addressing a fundamental oversight in classical mechanics:
the failure to recognize the dynamic mass component inherent in
kinetic energy. While classical mechanics accepts the inverse mass
relationship a ∝ 1/m in Newton's
second law; it never assigns physical meaning to the inverse-mass
term. ECM resolves this by interpreting 1/m as
a representation of negative apparent mass −Δm,
revealing that kinetic energy is carried by a real but negative
dynamic mass component.
Building
on this insight, ECM reformulates the force equation as:
Fᴇᴄᴍ
= (M + (−Mᵃᵖᵖ))⋅aᵉᶠᶠ =
Mᵉᶠᶠ⋅aᵉᶠᶠ
And
for systems consisting purely of dynamic energy (like photons), as:
Fᴇᴄᴍ
= (−2Mᵃᵖᵖ))⋅aᵉᶠᶠ
This
generalized formulation accounts for both static matter and massless
energy carriers by incorporating gravitational modulation of dynamic
mass. The chapter demonstrates how this correction not only completes
and extends classical mechanics, but also offers a consistent
mechanical explanation for photon behaviour, repulsive gravitational
effects (as in dark energy), and the cosmological gravitating
mass Mɢ .
ECM thus provides a unified framework linking classical force laws
with modern and cosmological physics by restoring the missing dynamic
mass component to the mechanics of energy.
1.
Classical Mechanics and the Hidden Mass of Kinetic Energy
In
classical mechanics, the force equation F=ma implies
that acceleration is inversely proportional to mass:
a ∝ 1/m
This
inverse dependence is mathematically consistent, but its physical
meaning is overlooked. If we reinterpret:
1/m
= −Δm
We
treat the inverse-mass effect as a negative mass component −Δm,
linked to the dynamic aspect of energy. Though not recognized
classically, this idea introduces a mass contribution originating not
from rest matter, but from motions itself—the dynamic mass of
kinetic energy.
In
the classical energy equation:
Eₜₒₜₐₗ
= PE + KE = mgh + ½mv²
We
now reinterpret:
m
−Δm as
the effective mass for potential energy,
−Δm as
the effective energetic mass contributing to kinetic energy.
Corrected
expressions become:
PE
= (m − Δm)gh, KE = ½(m−Δm)v² ⇒ −Δm
= dynamic energy carrier.
2.
The ECM Force Equation and the Role of Negative Apparent Mass
This
insight leads directly to the ECM force equation, which accounts for
both matter mass Mᴍ
and negative apparent mass −Mᵃᵖᵖ:
Fᴇᴄᴍ
= (M + (−Mᵃᵖᵖ))⋅aᵉᶠᶠ
= Mᵉᶠᶠ⋅aᵉᶠᶠ
Where:
Mᵉᶠᶠ is
the total effective mass participating in the force interaction,
aᵉᶠᶠ is
the effective acceleration derived from dynamic energy behaviour.
For
systems made entirely of dynamic energy (e.g., photons or unbound
electromagnetic energy), the ECM force law becomes:
Fᴇᴄᴍ
= (−2Mᵃᵖᵖ))⋅aᵉᶠᶠ
The
factor −2 arises
from:
the
intrinsic apparent mass −Mᵃᵖᵖ,
an
additional gravitational modulation analogous to the gravitational
energy contribution in massive systems.
3.
Extension to Modern and Cosmological Physics
Photon
Dynamics
Photons,
though massless in conventional models, carry energy and momentum.
ECM reconciles this by assigning photons a total negative dynamic
mass of −Mᵃᵖᵖ,
leading to the photon-specific force law:
Fᴇᴄᴍ
= (−2Mᵃᵖᵖ))⋅aᵉᶠᶠ
This
resolves the paradox of force and inertia in light: energy can exert
force through effective dynamic mass even in the absence of rest
mass.
Dark
Energy Analogy
ECM
identifies dark energy as a large-scale manifestation of photon
dynamic energy characterized by a single negative
apparent mass −Mᵃᵖᵖ,
not −2Mᵃᵖᵖ.
This
value represents the inherent energy of a photon after escaping
gravitational influence and expending the corresponding potential
energy. The remaining −Mᵃᵖᵖ persists
in zero-gravity spheres and dark-energy-dominated space and is
permanently expended as the photon undergoes cosmic redshift.
Thus,
the repulsive cosmological effect attributed to dark energy
corresponds to:
Fᴇᴄᴍ
= (−Mᵃᵖᵖ))⋅aᵉᶠᶠ
This
formulation reveals that the accelerated expansion of the universe is
a mechanical consequence of effective force acting on residual
dynamic mass in low-gravity space.
Cosmological
Models
In
cosmology, the gravitating mass Mɢ governs cosmic
expansion. ECM reformulates it as:
Mᵉᶠᶠ =
Mᴍ +
(−Mᵃᵖᵖ)
= Mɢ
This
corresponds directly to the framework in Chernin
et al. (2013),
where:
Mᴍ: matter
mass (ordinary + dark matter),
−Mᵃᵖᵖ: ECM’s
analogue of the cosmological dark energy term.
Thus,
ECM reinterprets cosmological gravitating mass Mɢ
as
a special case of its generalized effective mass framework.
4.
Conclusion
The
classical failure to recognize the negative dynamic mass of kinetic
energy created a critical theoretical gap. ECM closes this by:
assigning
real mass to dynamic energy,
completing
classical force and energy laws,
Providing
a consistent mechanical foundation for photons, dark energy, and
cosmic expansion.
ECM
not only redefines classical mechanics but also establishes a
coherent and unified view of modern and cosmological phenomena
through the physical reality of dynamic mass.
