Description
What is this formula?
The mass-energy equivalence formula states that mass and energy are two forms of the same physical quantity. It was introduced by Albert Einstein in special relativity and shows that a small amount of mass can correspond to a very large amount of energy.
When to use it
Use this formula when calculating energy released from mass conversion, nuclear reactions, particle physics processes, and relativistic systems.
Example
Data:
Mass:
m=0.001 kg
Formula:
E=mc²
Substitution:
E=(0.001)(3×10^8)²
Result:
E=9×10^13 J
