rotational energy
mechanics
Also known as: rotational kinetic energy
Quick Summary
Rotational kinetic energy is the energy an object possesses due to its rotation. It is calculated as half the product of its moment of inertia (I) and the square of its angular velocity ((\omega)), represented by the formula (\frac{1}{2}I\omega^2). This is analogous to translational kinetic energy, which is (\frac{1}{2}mv^2), where m is mass and v is linear velocity. Kinetic energy, in general, is the energy an object has because of its motion, whether that motion is translational, rotational, vibrational, or a combination.12
