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 the greater acceleration.
If the forces were exerted during identical time intervals, which would have the greater change in velocity?
Since the marble will accelerate faster, it would have the greater change in velocity.
Lets say that the ball has an acceleration a.
The marble has an acceleration of 2a.
ball
a * `dt = vF
vF * `dt = `ds
marble
2a * `dt = 2vF
2vF * `dt = 2`ds.
