How does one calculate and consider the rotational kinetic energy of a rotating object?

To calculate the rotational kinetic energy of a rotating object, you use the formula: KE 0.5 I 2, where KE is the rotational kinetic energy, I is the moment of inertia of the object, and is the angular velocity of the object. Moment of inertia is a measure of an object's resistance to changes in its rotation speed. Angular velocity is the rate at which the object rotates. By plugging these values into the formula, you can determine the rotational kinetic energy of the object.
