[70] [71] American physical chemists Gilbert N. Lewis and Richard C. Tolman used two variations of the formula in 1909: m = E / c 2 and m 0 = E 0 / c 2 , with E being the relativistic energy (the energy of an object when the object is moving), E 0 is the rest energy (the energy when not moving), m is the relativistic mass (the ...
Einstein Triangle. 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.
To calculate the binding energy we use the formula Z (m p + m e) + N m n − m nuclide where Z denotes the number of protons in the nuclides and N their number of neutrons. We take m p = 938.272 0813 (58) MeV/c 2, m e = 0.510 998 9461 (30) MeV/c 2 and m n = 939.565 4133 (58) MeV/c 2. The letter A denotes the sum of Z and N (number of nucleons ...
The photon's energy is converted to particle mass in accordance with Einstein's equation, E = mc 2; where E is energy, m is mass and c is the speed of light. The photon must have higher energy than the sum of the rest mass energies of an electron and positron (2 × 511 keV = 1.022 MeV, resulting in a photon wavelength of 1.2132 pm ) for the ...

The equivalence between mass and energy, as expressed by the formula E = mc 2, is the most famous consequence of special relativity. In relativity, mass and energy are two different ways of describing one physical quantity. If a physical system has energy, it also has the corresponding mass, and vice versa.
The equation sets forth that the energy of a body at rest (E) equals its mass (m) times the speed of light (c) squared, or E = mc 2. If a body gives off the energy L in the form of radiation, its mass diminishes by L/c 2. The fact that the energy withdrawn from the body becomes energy of radiation evidently makes no difference, so that we are ...
Why Does E=mc²? (And Why Should We Care?) is a 2009 book by the theoretical physicists Brian Cox and Jeff Forshaw . This was the first full-scale book from Professors Cox and Forshaw.
