Universal Gravitation

Objects in Motion, Chapter 4, The Law of Universal Gravitation.

This chapter brings together Kepler, Galileo, and Newton, especially the first and the last.  I created a review sheet listing their laws we covered next to a picture of each of them.

All I used for this class was a white board.  I read and we discussed, using the board to draw illustrations and to write equations.  It served as a good opportunity for review as well as an opportunity to consider the information in novel circumstances.

We considered and discussed the weakness of gravity, elliptical motion, "falling around" earth, wobbling planets, Newton's cannon, and satellite rockets.  It makes for good conversation...
