Look here. A bit on motion along curved paths, and another little bit on central forces.
The bit on curved paths I will assume you are familiar with at this point, or can pick it up quickly. We spent quite some time on it in PH125. If you were not in PH125, you will see it in Cal III very soon, or I'd be happy to go over it with you in office hours. It will come up gradually during the semester.
The bit on central forces is very incomplete, and follows the central force notes. Most of what you actually need to know about central forces this semester we will go over in class anyway, the skeleton notes I have up might be a useful reference down the road.
At some point, perhaps this semester, both will be merged into the 'math guide' anyway I suppose.
Should the far right side of Equation (1) in the `bit on central forces' read ``a_T * T-hat + a_N * N-hat''?
