The Lorentz factor (γ = 1/√(1-v²/c²) serves as a pivotal metric for determining the significance of relativistic effects. Typically, these effects become noticeable when γ deviates notably from 1, with a common threshold set at a deviation exceeding 1%. At a velocity where γ reaches 1.01, relativistic effects start to become appreciable, which typically occurs around 14% of the speed of light, precisely 41,970,944.12 meters per second. At this velocity, γ is approximately 1.01, marking the onset of measurable impacts on phenomena such as time dilation, length contraction, and mass increase.
Velocities significantly below this threshold, such as 0.8174% of c (v = 2,449,437.338 m/s or 0.008174c), exhibit noticeable relativistic effects in line with the Lorentz factor. For instance, at γ = 1.00001, the corresponding velocity v is approximately 2,449,437.338 m/s, representing approximately 0.8174% of the speed of light or 0.008174c. Similarly, at γ = 1.00000, the corresponding velocity v is approximately 2,449,288.829 m/s, representing approximately 0.8173% of the speed of light or 0.008173c.
Mathematical Threshold of Relativistic Effects in the Lorentz Factor:
Relativistic effects start to become appreciable at a velocity where γ reaches 1.01, which typically occurs around 14% of the speed of light, or precisely 41,970,944.12 meters per second. At this velocity, γ is approximately 1.01, marking the onset of noticeable impacts on phenomena such as time dilation, length contraction, and mass increase.
Even at velocities significantly below this threshold, for example, at γ = 1.00001, the corresponding velocity is approximately 2,449,437.338 m/s, representing approximately 0.8174% of the speed of light or 0.008174c. Thus, these velocities fall within the mathematical threshold where relativistic effects, in line with the Lorentz factor, become significant.
When γ = 1.00000, the corresponding velocity is approximately 2,449,288.829 m/s, representing approximately 0.8173% of the speed of light (0.008173c). Relativistic effects are noticeable only when γ deviates from 1.
