Why does the height of a bouncy ball decrease after each bounce?

Answer 1

Bouncy balls bounce because when the rubber hits a hard suface (one that cannot move away from the impact, usually the ground), the material of the ball is compressed at the point of contact. Once the energy of the ball's impact has been absorbed in this manner, the material of the ball reacts to the compression by attempting to return to an uncompressed state. To do so, it expands, pushing down against the hard surface, and pushing the entire ball back up from the surface. This may be enough to lift the ball back into the air. Gravity then drags the ball back down again, and the process repeats until the force of the rebound is too weak, and the ball will either stop, or translate the energy into a rolling motion along the hard surface.

Answer 2

Oh my dayies bouncy balls are simple to make they are make with a simple PVA glue and Borat solution and Starch mix together and you have finished making your bouncy if you wants to make it a different colour from the rest just add different food coloring into the paste roll into a balls leave to dry and have fun!

Answer 3

Balls don't bounce forever because some of the energy making the ball bounce is changed into thermal (heat) energy when it hits a surface. It will eventually stop bouncing when all of the kinetic and potential energy is changed to thermal energy.

Answer 4

Because each time the ball hits the ground, some of its kinetic energy is transformed to heat and sound energy, so it doesn't have as much left over to let it regain its original height.

Answer 5

Because of gravitatational forces and earth circumfrences.
