What Is Mass-Energy (E=mc²)?
Einstein's mass-energy equivalence shows that mass is a form of energy and corresponds to a very large amount of energy.
How is it calculated?
How Is It Calculated?
E = m × c² (c = 3×10⁸ m/s)
- Enter the mass (kg).
- It is multiplied by the square of the speed of light.
Even tiny masses correspond to enormous amounts of energy.
