PRELIMINARY QUESTIONS 1. Consider a head-on collision between two identical billiard balls. Ball 1 is initially in motion toward ball 2, which is initially at rest. After the collision, ball 2 departs with the same velocity that ball 1 originally had. Disregard any friction between the balls and the surface. What happens to ball 1? What happens to ball 2?

Sketch a position vs. time graph for each ball in Preliminary Question 1, starting with the time before the collision starts and ending a short time after the collision. 3. Based on your graph from Preliminary Question 2, is momentum conserved in this collision? Is kinetic energy conserved? 1
