If you dropped a large leaf from the Empire State Building, what would its speed vs.time graph look like? How might it differ from that of a baseball?
The graph of the leaf would show the speed increasing for a certain amount of time until it reaches terminal velocity. At this point, the speed would be constant until it hits the ground where the velocity would become 0 almost instantaneously.
The graph for the baseball would show a constant increase in speed until the point where the ball contacts the ground, where the speed would become 0 almost instantaneously.
