Storing energy in a bouncing ball

In summary, the conversation discusses the storage and release of energy in a ball during an impact. The molecules in the ball exert forces on each other, storing energy, which is released upon rebound. The energy is stored as elastic potential energy, due to electromagnetic bonds between atoms. There is no change in electron orbits during elastic deformation.

I found this text

As the ball's surface dents during an impact, these polymer molecules move about and begin to exert forces on one another (storing energy in the process). As the ball rebounds, these molecules release their stored energy and push the ball back into the air.

I'm not sure where this energy is stored. Is it just transformed from kinetic to potential? is it stored in the orbits of the electrons? do the electrons descend from a higher to a lower orbit when they hit the wall? if so, i don't see why.

It is elastic potential energy, due to atoms pushing each other around. The bonds are electromagnetic; the electrons do not change orbits with elastic deformation.

ok, thanks.
 

1. How does a bouncing ball store energy?

A bouncing ball stores energy through the deformation of its material as it hits the ground, which causes it to compress and then expand, converting kinetic energy into potential energy. This stored energy is then released as the ball bounces back up.

2. Can any type of ball store energy through bouncing?

Yes, most types of balls can store energy through bouncing, as long as they have some level of elasticity in their material. Materials such as rubber, plastic, and foam are commonly used in bouncing balls.

3. How much energy can be stored in a bouncing ball?

The amount of energy stored in a bouncing ball depends on various factors such as the material, size, and weight of the ball, as well as the height from which it is dropped. In general, the higher the drop height, the more energy the ball can store.

4. Can the energy stored in a bouncing ball be harnessed for practical use?

Yes, the energy stored in a bouncing ball can be harnessed for practical use through various methods such as piezoelectricity, which converts mechanical energy into electrical energy. This energy can then be used to power devices such as watches, calculators, and even streetlights.

5. Is storing energy in a bouncing ball a sustainable method?

Yes, storing energy in a bouncing ball can be considered a sustainable method as it does not require any external energy source and relies on the natural forces of gravity and elasticity. However, the efficiency of this method may vary and is still being explored for potential applications.
