The kinetic energy of an electron (or anything else, for that matter) at rest is zero.

The total energy of the electron, calculated from ##E=\gamma{m_0}c^2## or ##E^2=(m_0c^2)^2+(pc)^2"##, is .511~~511~~ MeV when the electron is at rest and greater when it is moving and the kinetic energy is non-zero.

[Edit - left the decimal point out the first time around]

.511MeV or 511keV bro, 511MeV is some ginormous electron.The kinetic energy of an electron (or anything else, for that matter) at rest is zero.

It's overweight even for a muon.511MeV is some ginormous electron.
