kinetic energy
kinetic energy The energy possessed by a body by virtue of its motion in space. It is equivalent to the work that would be done if the moving body were brought to rest. When the speed of a body is much less than the speed of light, kinetic energy is equal to ½mv2, where m is the mass of the body and v is its velocity. A rotating body has kinetic energy ½I ω2, where I is its moment of inertia and ω is its angular velocity.

kinetic energy
kinetic energy (symbol K) Energy that an object possesses because it is in motion. It is the energy given to an object to set it in motion; it depends on the mass (m) of the object and its velocity (v), according to the equation K = 1/2 mv2. On impact, it is converted into other forms of energy such as heat, sound and light. See also potential energy
