A steel ball rolls down a ramp and collides with a marble, as in the video. The marble is slightly smaller and quite a bit less massive than the ball.

• If they both experience the same force, which will have the greater acceleration?

answer/question/discussion:

The marble will have higher acceleration because A=f/m and since it has the smaller mass, A will be greater.

• If the forces were exerted during identical time intervals, which would have the greater change in velocity?

answer/question/discussion:

The marble will have the greater change in velocity because the accelerations occur over the same time period.

Very good. Well-stated explanations.
