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 will have greater acceleration. Since F=ma if mass increases, acceleration must decrease to maintain the same force.

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

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

Since `dv=a`dt the marble would also have the greater change in velocity. Since the time is the same, the one with the higher acceleration will have a greater change in velocity.
