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 believe the marble will have greater acceleration.

• If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion: ->->->->->->->->->->->-> :
I would say the steel ball would have the greater change in velocity.
The time interval during which the forces are exerted is the same for both. So the one with the greater acceleration will have the greater change in speed.
