Test corrections are due at the beginning of class on Monday- NO EXCEPTIONS.

- To earn points, explanations of what was wrong (with the correct solution) need to be provided.
- If you scored lower than 70% (74 out of 105 points), you must discuss the test with me to earn the points. Others are more than welcome to talk with me about the test, but aren’t required.
- You can earn up 25% of your missed points.

Any new contracts must be turned in by Wednesday.

Today, we'll begin our tour of rotating systems. Much of this unit will seem familiar: we will describe motion (kinematics), talk about what causes motion (dynamics), and look at two cosnerved quantities- energy and angular momentum.
