Energy and Collisions Quiz

What would be a scientific question that could be tested by exploring the way the ball bounces in “Wall Ball”?

• If I change the color of the ball will it have more or less energy?

• Will the ball bounce against the wall?

• If I change the size of the ball, will it affect the amount of energy when it bounces back?

• If I throw the ball faster, will it affect the energy of the ball as it bounces back?

Which two ways is energy transferred by the contact force in the student’s experiment?

• It changed the shape of each of the billiard balls.

• It caused sound and heat energy to be released into the air.

• It caused electrical and light energy to be released into the air.

• It caused the motion of both billiard balls to stop.

• It changed the motion of both billiard balls.
