Abstract

I give new relativistic formulas for kinetic, rest and total energies. The change in kinetic energy of a particle will be determined as the work done by the spatial part of the Minkowski four-force. The new relativistic kinetic energy and its relation with the spatial part of the fourmomentum are given by the expressions similar to its classical equivalents. In particular, I justi ed that the rest energy is half of the amount determined by the traditional relation. I present a new interpretation of the temporal component of the Minkowski four-force
