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)
