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, which has a smaller mass, will experience a greater acceleration since energy doesn’t have to work as hard to propel it as it did with the larger mass.

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

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

Again because the marble is smaller it should encounter a greater change in velocity since the time interval multiplied by the acceleration, which for the marble is faster, will result in a larger `dv.
