Abstract

Some authors confirm that the energy of a physical system conserves in an inertial frame of referencemust do so in any other frames. Actually they have confused the covariance of equations with the principle of relativity. The present article attempts to clear up this misunderstanding.

Key words： principle of relativity; covariance of equations; energy conservation
