When would you use equation I=mr^2 in rotational motions? I know there are different types of equations in finding the value of the moment of inertia, but then where would you use that above equation?

OpenStudy (anonymous):

That is the Inertia equation for a "point" mass where it means it will be a point revolved around a rotational axis
