Answer to Question #92104 in Mechanics | Relativity for Favour Ongbabo

Question

Show a relationship between potential, kinetic and rest energy proving which is normally higher than the rest

Answer 1

When the mass is moving then the moving mass posses more energy then the mass at rest due to Lorentz contraction factor.

Moving mass energy is the sum of relativistic kinetic energy and rest mass energy. Thus,

Relativistic kinetic energy is the difference of total energy due to moving mass and the rest mass energy.

Relativistic kinetic energy is KE_rel = (γ − 1)mc²

$\gamma=\frac{1}{\sqrt{ (1-v^2/c^2) }}$
