<p>Do I? There's a chart in my book of 8 objects with their moments of inertia, must i memorize this or would they give it to me on the test?</p>
<p>it might help on the multiple choice, but in frqs, they either give it to you or you have to derive the moment of inertia
i would memorize the rotational inertia of a hoop, disk, solid sphere, hollow sphere, and rod about central axis
also know the parallel axis theorem</p>
