When a rubber ball is bounced, its molecular structure causes it to compress, but it cannot equalize the pressure by expanding on the other side, so the pent-up energy is rapidly used by decompressing the ball which causes the bounce.
Because balls are made of rubber, and dogs are not.
They are hollow rubber balls. Hope this helps!
Glass balls tend to bounce higher than rubber balls due to their density and hardness. Glass balls have less energy loss upon impact because they are rigid and less deformable compared to rubber balls. This allows glass balls to retain more of their original kinetic energy during the bounce, resulting in a higher bounce height.
Some things that bounce but are not balls include rubber bands, springs, and trampolines.
To make them bounce.
Modern tennis balls are made of a hollow rubber core, covered in a wool or nylon shell which is known as the nap. Pressurised air inside the rubber core makes the ball bounce.
Small rubber bouncy balls bounce higher than other balls because they are made from materials with higher elasticity, allowing them to store and release more energy during impact. Their size and lightweight also contribute to their increased bounce height as they experience less air resistance.
Yes, a cold rubber ball can still bounce. The bounce height might be slightly lower compared to when the ball is warm due to the rubber hardening in colder temperatures, but it will still exhibit bouncing behavior.

Rubber helps Tennis Balls bounce better. If you get the kind of tennis balls with a very solid and not hollow rubber, it won't bounce. If it's hollow it will bounce way better. How could tennis balls not bounce without rubber? Tennis balls are made of rubber because it helps it bounce. This may sound silly, but how could a tennis ball bounce without being made of rubber? Tennis balls need rubber so that when they come into contact with the ground they do not burst or crack. It will dent slightly and go back to its original form. This is an advantage to a tennis ball being made out of rubber. so it can bounce.
Basketballs are not at the top of the list of bouncebility (see tennis balls). SorryHowever balls bounce because they are deformed when they hit something and the rubber forces them back into a round shape which propels then off the surface they hit.The more power in the rubbers desire to maintain its shape vs the weight of the ball determines its bounce.
Bouncy balls are typically made of rubber or a similar material called synthetic rubber, such as polybutadiene or polyisoprene. These materials are chosen for their elasticity and ability to bounce.
