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:
I think that the smaller marble will have greater acceleration. More energy will be transferred to the smaller marble.

• If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion:
I still think that the velocity would also be greater with the smaller marble. I think about a child sitting at the edge of a slide waiting for another child to slide down. The smaller child will be thrown off hard and farther than a large child.
