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 it depends on the weight of the object. If the steel ball weighs more then I would assume that it would have a greater acceleration than the marble.

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

answer/question/discussion: ->->->->->->->->->->->-> :

If the steel ball is going to have a greater acceleration then I would assume that it would also have a greater change in the velocity. If it is moving faster then it will travel a further distance in a shorter amount of time and have a greater change in velocity.
