Introduction
Physics is the science that allows us to understand the fundamental behaviors of the universe. It can be
explored at the macroscopic and microscopic levels, giving insight into the way objects interact.
Here we will take a look at how physics can be applied to the game of pool. Almost all of the different
aspects of pool can be explained through physics, and a better understanding of these fundemental
principles can aid in performance playing pool.
In the game of pool there are sixteen balls, one cueball and fifteen physically identical numbered balls.
While there are many interactions between all the balls on the table, in order to simplify things we will
only look at the interactions between the cue ball and the first ball it strikes. These principles can be
expanded to evaluate the entire system of balls on the pool table.
The focus of this site is to evaluate the Motion, Work, and Energy involved in a game of pool. The
Motion is inclusive of the direction of the ball when struck by another ball and how it will travel after
hitting the edge of the pool table. The Work will determine how hard the cue ball must be struck in
order for the ball to travel a specific distance. Lastly, the Energy transferred through the system will be
evaluated.
