However the total energy of the particle E and its relativistic momentum p are frame-dependent relative motion between two frames causes the observers in those frames to measure different values of the particle's energy and momentum one frame measures E and p, while the other frame measures E ′ and p′, where E ′ ≠ E and p′ ≠ p, unless there is no relative motion between observers, in which case each observer measures the same energy and momenta. The invariant mass (or rest mass) is an invariant for all frames of reference (hence the name), not just in inertial frames in flat spacetime, but also accelerated frames traveling through curved spacetime (see below). in its center-of-momentum frame ( p = 0), we have E = E 0 and m = m 0 thus the energy–momentum relation and both forms of the mass–energy relation (mentioned above) all become the same.Ī more general form of relation ( 1) holds for general relativity.

If the body's speed v is much less than c, then ( 1) reduces to E = 1 / 2 m 0v 2 + m 0 c 2 that is, the body's total energy is simply its classical kinetic energy ( 1 / 2 m 0 v 2) plus its rest energy. momentum mass × velocity p mv This is when: momentum (p) is measured in kilogram metres per second (kg m/s) mass (m) is measured in kilograms (kg) velocity (v) is measured in metres per.For photons, this is the relation, discovered in 19th century classical electromagnetism, between radiant momentum (causing radiation pressure) and radiant energy. We operate in New Jersey, New York, California, Florida, Texas, Connecticut, Pennsylvania, Arizona, Nevada, and Massachusetts. 500 as one of the fastest-growing private companies, Momentum Solar employs over 2,000 people nationwide. Vectoris a fancy word for saying the direction matters. If the body is a massless particle ( m 0 = 0), then ( 1) reduces to E = pc. Momentum Solar is one of the leading residential solar contractors in the United States. This makes a lot of sense, because pmv and mass is measured in kg, velocity is measured in meters per second (m/s), so we would expect momentum (mass x velocity) to be I/ O.All three equations hold true simultaneously. Unlike either of those equations, the energy–momentum equation ( 1) relates the total energy to the rest mass m 0. The energy–momentum relation is consistent with the familiar mass–energy relation in both its interpretations: E = mc 2 relates total energy E to the (total) relativistic mass m (alternatively denoted m rel or m tot ), while E 0 = m 0 c 2 relates rest energy E 0 to (invariant) rest mass m 0.
