kinetic energy | Definition & Formula | Britannica

Kinetic energy, form of energy that an object or a particle has by reason of its motion. Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass. The kind of motion may be translation, rotation about an axis, vibration, or any combination of motions.
