## Mass-Energy Equivalence

Einstein's equation reveals that mass and energy are interchangeable.

### Formula

**E = mc²**

where c = 299,792,458 m/s is the speed of light. A tiny amount of mass corresponds to an enormous amount of energy. This is the principle behind nuclear power and nuclear weapons.

Exemplo Resolvido

1 kg of matter fully converted to energy.

  1. E = mc²
  2. E = 1 * (2.998e8)²
  3. E = 8.988e16 J
  4. E = 2.497e10 kWh
  5. That is about 21.5 kilotons of TNT equivalent.
