Kinetic energy

The Work-energy Theorem says[32] the change in kinetic energy is equal to the work done on the body, that is

(Click [show] for intermediate steps)

If in the initial state the body was at rest (γ0 = 1) and in the final state it has speed v (γ1 = γ), the kinetic energy is K = (γ − 1)mc2, a result that can be directly obtained by subtracting the rest energy mc2 from the total relativistic energy γmc2.
