Today, we'll spend the period first learning about what moment of inertia is and then trying to figure out how to calculate the moment of inertia of different objects.  We'll learn formulas for moment of inertia using a summation for discrete objects and then an integral for continuous bodies.

Then, we'll work on problems from Chapter 10 on calculating moment of inertia:
Required: 42, 46, 47a, 49
Enrichment: 50

Homework:  Watch the following video by Dan Fullerton on Rotational Dynamics.  Watch ONLY from 6:06 to 19:30!  Take your time working through these examples to really understand them.  It would be a good idea to have these examples written down in your notes.
