Kinetic energy

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

<math> E_k = \frac{1}{2} m v^2 </math>.

If a body is rotating, its rotational kinetic energy equals Iω2/2, where I is its moment of inertia and ω its angular velocity.
