If the net torque is not zero, a body will undergo angular acceleration. We
know how to compute torque as force times moment arm. We first review
equilibrium and then ask if we can determine the resulting angular acceleration
when their is a nonzero net torque. This leads to the analog of Newton's Second
Law and the moment of inertia. With these analogs, we can then write down
analogs for work, energy and momentum. We end showing how rotational kinetic
energy figures into the conservation of energy by examining objects rolling down
an incline. (We will discuss angular momentum in the next class.)

The main topics are:

- Newton's Second Law for Rotational Motion
- Moments of Inertia
- Rotational Expressions for Work, Energy and Momentum
- Total Kinetic Energy = Translation KE + Rotational KE
- Energy Conservation for Rolling Objects (without slipping)
