SEED 17.1
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 because acceleration is greater in objects with less mass: a = f/m
If the forces were exerted during identical time intervals, which would have the greater change in velocity?
answer/question/discussion: The marble would have a greater change in velocity because it has the greater acceleration
'dv = a * 'dt
