Central Forces and Angular Momentum

Much of the material in Chap. 1 will be a review for many of the students using this text. However, indicial notation for vectors will be used throughout this chapter and much of the book, and while most students have been exposed to this notation previously, experience has shown that many have yet to master it. It is not at all difficult and allows for such straightforward proofs of angular momentum relations that it is highly effective to become proficient with it.
