The following formula is used to determine rotational kinetic energy: 1/2(Iw^2). This equation is similar to the one used to determine kinetic energy in linear form, which is 1/2mv^2.
Rotational kinetic energy moves about the object's center of mass. The "I" represents the rotational inertia for the given object. The specific equation associated with rotational inertia varies by the geometry of the object. The "w," which is the Greek letter omega, represents the angular velocity of the object. Angular velocity is equal to the angle through which an object rotates divided by the time it took. This applies to a given fixed axis of rotation.
