The energy–momentum relation is consistent with the familiar mass–energy relation in both its interpretations: E = mc relates total energy E to the (total) relativistic mass m (alternatively denoted mrel or mtot ), while E0 = m0c relates rest energy E0 to (invariant) rest mass m0. Unlike either of those … Meer weergeven In physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation relating total energy (which is also called relativistic energy) to invariant mass (which is also called rest mass) and Meer weergeven 1. If the body is a massless particle (m0 = 0), then (1) reduces to E = pc. For photons, this is the relation, discovered in 19th century classical electromagnetism, between radiant momentum (causing radiation pressure) and radiant energy. 2. If the body's … Meer weergeven Centre-of-momentum frame (one particle) For a body in its rest frame, the momentum is zero, so the equation simplifies to $${\displaystyle E_{0}=m_{0}c^{2}\,,}$$ where m0 is the rest mass of the body.
