a. Have students differentiate between
elastic and inelastic collisions. In which is mechanical energy
conserved? In which is linear momentum conserved?
b. What type of collision occurs when
a pool ball strikes another pool ball?
c. Explain how the cue ball is used
(i.e., perfectly elastic collision between a stationary ball and
a moving (cue) ball, what happens to the kinetic energy and momentum
of the stationary ball when it is struck by the moving ball).
d. Other then pool, what are some practical
uses of elastic collisions (e.g., particle accelerator)?
