The kinetic energy of rotation can be expressed by the equation: KE rotation = 1 2 I ω 2 . In this equation, ω is the angular velocity – it measures how quickly our catapult arm spins around its axle. I . is the moment of inertia. For our launch arm, this is the same as a rod rotating on its end, or:

Because of kinetic friction, the two disks eventually attain a common angular velocity . Find . In the collision of the two disks in Example 10-4, mechanical energy is dissipated. We can see this by writing the energy in terms of the angular momentum. An object rotating with an angular velocity ω has kinetic energy.
