### Rotational Motion: Moment of Inertia

The moment of inertia, I, is a measure of the way the mass is distributed on the object and determines its resistance to angular acceleration. Every rigid object has a de nite moment of inertia about a particular axis of rotation. The moment of inertia of a collection of masses is given by: I= mir i 2 (8.3)
