Feb 20, 2022 · To expand our concept of rotational inertia, we define the moment of inertia \(I\) of an object to be the sum of \(mr^2\) for all the point masses of which it is composed. That is, \(I = \sum mr^2\). Here \(I\) is analogous to \(m\) in translational motion. Because of the distance \(r\), the moment of inertia for any object depends on the ...
