difference between relatavistic kinetic energy and normal kinetic energy

Kennalj

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.
