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: ->->->->->->->->->->->-> :Since the force is same,
m1a1=m2a2
m1/m2=a2/a1
So we get that the acceleration is inversely proportional to the mass ,if the force is same.
Sounds like,steel ball is heavier ,so acceleration would be more for marble.
• If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion: ->->->->->->->->->->->-> : Well,its again the same situation.
As the time intervals are same, and we know that acceleration is directly proportional to change in velocity, so marble will have greater change in velocity
