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 force=Mass* acceleration, the marble, whose mass is less that the steel ball, will experience a greater acceleration.

If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion:
Assuming that the marble is accelerating faster, than it will have a greater change in velocity given a identical time interval.
