Write Einstein's mass-energy equation. Give the meaning of each symbol which occurs in it.

Einstein's mass-energy equation is, E=mc2,

The equation is derived directly from Einstein’s Special Theory of Relativity

Each of the letters of E = mc2 stands for a particular physical quantity. Writing them out in full we get:

E = energy (measured in joules, J)

m = mass (measured in kilograms, kg)

c = the speed of light (measured in meter per second, ms-1)
