In physics, kinetic energy is energy possessed by a body by virtue of its motion. If the body with mass m is moving in a straight line with velocity v, its translational kinetic energy amounts to

E_{k}={\frac {1}{2}}mv^{2}

If a body is rotating, its rotational kinetic energy equals Iω/2, where I is its moment of inertia and ω its angular velocity.
