A tennis ball is placed on top of a basketball then dropped from some height. Because of the transfer of momentum, the tennis ball rebounds very high into the air while the basketball does not.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Place Balls on the lab table so they will not roll off.
Balance the tennis ball on top of the basketball in the center. Release the balls and watch them bounce. The tennis ball will go very high while the basketball does not.
Notes:
Be sure to perform in a high ceiling area or outside.
If the tennis ball is not centered it will fly off to the side.
Some practice ahead of time helps with this demo.
