The equation E = mc^2 is a famous formula in physics, first proposed by Albert Einstein in his 1905 paper “Does the Inertia of a Body Depend Upon Its Energy Content?”

The equation shows the relationship between mass (m), energy (E), and the speed of light (c).

To derive this equation, Einstein made use of the theory of special relativity and the principle of mass-energy equivalence. According to this principle, mass and energy are equivalent and can be converted from one form to another.

Here’s a brief overview of the derivation:

According to special relativity, the energy (E) of an object at rest with mass (m) can be calculated using the equation E = mc^2.

This equation shows that a small amount of mass can be converted into a large amount of energy, and vice versa.

This principle was later confirmed by experiments involving nuclear reactions, where small amounts of mass were converted into large amounts of energy.

Therefore, the equation E = mc^2 is a fundamental equation in physics that represents the equivalence of mass and energy.
