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 experienced the same force, which would have the greater acceleration?
The smaller ball will have a greater acceleration.
answer/question/discussion:
• If the forces were exerted during identical time intervals, which would have the greater change in velocity?
The smaller ball will have a greater change in velocity. It will have greater acceleration, and stop to a halt sooner when it collides with the bigger marble.
