Total energy via momentum and rest mass

The energy—momentum relation, also called relativistic dispersion relation, is a relativistic equation relating total energy to invariant mass and momentum. It is the extension of mass-energy equivalence (Total energy via relativistic mass) for bodies or systems with non-zero momentum.
