I was looking at the relativistic energy of an electron and noticed that the formula for kinetic energy is:
K.E. = mc^2 m0c^2 How is this related to the kinetic energy for low speed particles? Does anyone have a link to the proof?

This can be written as (Gamma  1) m_0c^2. Do a taylor expansion of gamma and the result immediately follows.
