can and then drops them at the same time. The diagram shows the two balls falling together
and then bouncing. The basketball does not bounce quite as high as it would have bounced had Carly dropped only it.

basketball to the tennis ball.
The tennis ball bounced extra high because kinetic energy was transferred from the
tennis ball to the basketball.

ground directly to the tennis ball.

faster because gravity has a greater effect on the car than the driver.
