Definitions
noun
Mass and energy as a unified concept.
Whereas in classical physics mass and energy are distinct concepts, on relativistic scales, they become indistinguishable and are replaced by mass-energy.
In higher-energy physics, mass and energy eventually become meaningless as individual concepts; a particle's so-called "mass" is actually mass-energy and is often given equivalently in units of either mass (GeV/c²) or energy (GeV).
The energy associated with any given mass according to special relativity, E = mc².
adj
mass-to-energy
Mass-energy conversion occurs during nuclear fusion and fission.
