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.
