Expert Answer
- E = mc 2 is an equation discovered by German born scientist Albert Einstein, who in his theory of special relativity expressed a fact that mass and energy are similar physical entities and can be converted into each other.
- In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c 2) is equal to the kinetic energy (E) of that body.
- Before this theory of Einstein, mass and energy were considered as distinct entities but its only after this equation that the world has understood the realtionship between mass and energy.
