Perfectly Elastic Collisions
Imagine two billiard balls on a pool table. Ball A has a mass of 2 kilograms and ball
B has a mass of 3 kilograms. The initial velocity of ball A is 9 meters per second to
the right, and the initial velocity of the ball B is 6 meters per second to the left. The
final velocity of ball A is 9 meters per second to the left, while the final velocity of
ball B is 6 meters per second to the right.
1. Explain what happens to each ball after the collision. Why do you think this
occurs? Which of Newton’s laws does this represent?

Answer 1

2. What can you say about the total momentum before and after the collision?
3. What do you think would happen to the velocity of each ball after the
collision if the masses and initial velocities of each ball were the same?

Answer 2

4. The mass of ball A is 10 kilograms and the mass of ball B is 5 kilograms. If
the initial velocity is set to 3 meters per second for each ball, what is the
final velocity of ball B if the final velocity of ball A is 2 meters per second?
Use the elastic collision equation to find the final velocity of ball B. Assume
ball A initially moves from right to left and ball B moves in the opposite
direction. Identify each mass, velocity, and unknown. Show your work,
including units, and indicate the direction of ball B in your answer.
5. If the mass of each ball were the same, but the velocity of ball A were twice
as much as ball B, what do you think would happen to the final velocity of
each ball after the collision? To answer this question, create a hypothesis in
the form of an if-then statement. The “if” is the independent variable, or the
thing that is being changed. The “then” is the dependent variable, or what
you will measure as the outcome.
