Explanation:

This formula states that mass has an equivalent energy (E) which can be calculated as mass (m) multiplied by the speed of light squared (c2). Similarly, energy has an equivalent mass (m) which can be calculated as energy (E) divided by the speed of light squared (c2). Because the speed of light is a large number in everyday units (approximately 3×108 m/s), the formula implies that even an everyday object at rest with a modest amount of mass has a very large amount of intrinsic energy. Chemical reactions, nuclear reactions, and other energy transformations may cause a system to lose some of its energy content to the environment (and thus some corresponding mass), for example, by releasing it as thermal energy or as radiant energy, such as light.

Mass–energy equivalence arose originally from special relativity as a paradox described by Henri Poincaré.[2] Einstein proposed it on 21 November 1905, in the paper Does the inertia of a body depend upon its energy-content?, one of his Annus Mirabilis (Miraculous Year) papers.[3] Einstein was the first to propose that the equivalence of mass and energy is a general principle and a consequence of the symmetries of space and time.

A consequence of the mass–energy equivalence is that if a body or system is overall motionless (in other words, within its center-of-momentum frame), it still has internal or intrinsic energy, called its rest energy, which is directly proportional to its rest mass, and is independent of the composition of its matter. Rest mass is mass measured while having no momentum; it is also called invariant mass, as it is a property that remains independent of overall momentum, even at extreme speeds approaching the speed of light.

When a body or system has overall momentum, its total energy (which is also called relativistic energy) is greater than its rest energy, and is equal to the sum of its rest energy and kinetic energy (that is, energy due to motion). The energy–momentum relation is the relation between a body's or system's total energy, rest mass and overall momentum. The relativistic mass of a body or system can be derived from its total energy divided by the speed of light squared; and for a body or system with overall momentum its relativistic mass will be greater than its rest mass, as it will have more energy than at rest
