Answer 1

This is the theory of Einstein and we all know it by Relativity Theory.

First of there were two postulate:-

1. The Principle of Relativity.

2. The Principle of Constancy of the speed of Light.

This equation cannot be proved hence we can derive it.

Relativistic Kinetic energy= E-mc²

E= Ke(Kinetic energy) + mc²

If the Kinetic energy of a moving body is zero then we can,

E=0+ mc²

Hence,

E= mc²

This standard equation stands for the Kinetic Energy

E = Kinetic Energy

m= mass of the body

c²= (speed of light)²
