WebOct 27, 2024 · You need to subtract the rest energy from the total energy to get the kinetic energy, so that kinetic energy is zero for a body at rest. In other words, $$\text{KE} = (\gamma-1)mc^2.$$ You will find that this expression reduces to $\frac{1}{2}mv^2$ at … WebOct 8, 2024 · In perfectly inelastic collision, the loss in kinetic energy during collision is transformed to another form of energy like sound, thermal, heat, light etc. Let KE i be the total kinetic energy before collision and KE f be the total kinetic energy after collision. Total kinetic energy before collision, Then the loss of kinetic energy is
