Introduction

One of the most famous equations in physics is Albert Einstein’s mass-energy equivalence formula:

[
E = mc^2
]

In this equation:

- (E) represents energy,
- (m) represents mass,
- (c) is the speed of light in a vacuum (~ (3.00 \times 10^8) meters per second).

This equation expresses a profound concept: that mass and energy are interchangeable and fundamentally the same entity.
