How can I learn about billiard physics?
There are several books available that discuss the physics of balls on cloth struck by pointed sticks. A fairly non-technical treatment is in Jack Koehler’s “The Science of Pocket Billiards”. It has many good observations and plausible explanations but no real theory or equations. For the latter, get Wayland Marlow’s “The Physics of Pocket Billiards” which has great steaming piles of equations. It is available from the author at MAST, Wayland C. Marlow, 2738 Ohina Street, Kihei HI 96753-8548, for $41.50 including shipping.

These include theory and equations and diagrams, along with useful worked examples. If you have access to a college physics library, many “mechanics” texts from around 1900 have entire c
