Aim
•
Make a small hole in a ping pong ball, fill
it with some liquid and seal the hole.
Drop the ball from the fixed height and
investigate how high it bounces,
depending on the amount of liquid inside
Theoretical part
•
Loss of mechanical energy can be calculated
as:
∆E=mg(h-H
0
)
h − height of bounch
H
0
=const=0,1m − height of fall
Theoretical part
KE=max, PE=0
KE=0, PE=max
Conclusion
•
As the fall height increases, the loss of
mechanical energy decreases
•
As the volume of the water increases, the loss
of mechanical energy also increases

This experiment explores how the amount of liquid inside a ping pong ball affects its bounce height, energy loss, and overall performance. By analyzing the relationship between liquid volume, fall height, and mechanical energy, fascinating insights were obtained. As the fall height increases, the loss of mechanical energy decreases, while increasing the water volume leads to higher energy loss. These findings provide valuable data for further studies in physics and material science.
