Ball Bounce Experiment
Materials for the Ball Bounce Experiment:
A basketball or soccer ball, or similar bouncy ball
a smaller bouncy ball (like a tennis ball or a racquet ball).
Have an assortment of other balls handy for further experimenting.
Procedure:
Do this experiment outside
First bounce the basketball and tennis ball side by side to compare their bounces. Start them off around chest height
Make a hypothesis (a guess) about what will happen when you stack the small ball on top of the bigger one and then drop it
Try it! It may take a couple tries to line them up just right but the results are pretty awesome
Explanation:
The energy of motion from the bigger ball is transferred into the smaller one. Most of your attention is on the sky-rocketing smaller ball, but if you look at the basketball, it doesn’t have much bounce at all!
Experiment further:
Hopefully this will make you think of other things. Like what if you switched the two balls and dropped the smaller one on the bottom? What if you used two of the same sized ball? A golf ball on top? Think of other things!
you will notice that ball with not move
it is due to Newton first law
according to Newton first law the body will not change its state until force is applied
