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? the marble will have greater acceleration because mass is less if the force is the same a = F/m will be greater , than a = F/m for the steel ball which has a greater mass
answer/question/discussion:
If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion: the marble will have the greater change in velocity using `dv = a`dt, where a is greater for the marble with less mass
