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 forces of the same magnitude (in this case, equal and opposite forces), which will have an acceleration of the greater magnitude?
answer/question/discussion: ->->->->->->->->->->->-> :
a = F / m, marble has less mass, marble will experience greater acceleration

If the forces were exerted during identical time intervals, which would have the greater change in speed?
answer/question/discussion: ->->->->->->->->->->->-> :
The marble will have a greater change in speed, having greater acceleration and acting over the same time
