### kinetic energy

**(KE)**
(an object's energy due to its motion)

**Kinetic energy** is the energy an object has due to
its motion. Classical formula:

1
ke = ——— mv²
2

Relativistic:

mc²
ke = ————————————— — mc²
√ 1 - v²/c²

The relativistic formula produces virtually the same amount as the
classical formula unless the speed is very fast, i.e., a good fraction
of the speed of light.

**Thermal energy**, the energy due to a substance's temperature,
is kinetic energy: on a microscopic scale,
it is the energy of the movement of particles.
