Calculate the velocity of an electron whose kinetic energy is 2 MeV (Hint: It is relativistic.) Strategy. and the millennium relativity gamma factor 2 in the form . PCB said: Energy= p*v That doesn't look like any formula for relativistic energy that I know of, either for total energy or kinetic energy. The expression for relativistic kinetic energy is always correct, but for Part 1 it must be used since the velocity is highly relativistic (close to c). However, even if an object is changing internally, so long as it does not exchange energy or momentum with its … Calculating energy content [edit | edit source].
