What energy transformations occur when you bounce a ball?

Answer 1

A Basketball depends on pressurized air for its bounciness. When the ball hits the court, it compresses that air and the air stores energy in its compression. The ball's rebound is powered by the air returning to its original characteristics. The ball's skin, on the other hand, isn't all that bouncy and doesn't store energy well. To bounce well, the basketball needs to store energy in its air during the bounce, not in its skin. That's why it's important to have an air pump so that you can keep your basketball properly inflated. When you cool a basketball, however, you reduce the pressure of its air. That's because the air molecules have less thermal energy at colder temperatures and thermal energy is responsible for air pressure. A basketball that was properly inflated at warm temperature becomes under-inflated when you cool it down. At the same time, the basketball's skin becomes less elastic and more leathery at cool temperatures. So the basketball suffers from under-inflation and from a leathery, not-very-bouncy skin. If you cool a basketball to low enough temperature, its skin will freeze and become brittle. Just how low the temperature has to go depends on the material used in to make the basketball. I've never seen a basketball shatter on the court, even in pretty cold weather, so I doubt you can "freeze" one in a household freezer. But I'm sure that a dip in liquid nitrogen at -395 °F would do the trick. I often freeze rubber handballs in liquid nitrogen for my class and then shatter them on the floor.
when it hits a surface it is compressed, the molecules inside it are pushed closer together, and then they repel each other causing the softball to bounce.

Answer 2

Gravity makes the ball fall. It doesn't make it bounce. The ball bounces because, when it hits the ground, its momentum makes it continue to fall for a fraction of a second, causing the part touching the ground to collapse slightly (depending on how stiff or elastic the ball is). The collapsed part then straightens itself out again rapidly, flicking the ball up as a bounce.

Technically, a ball that does not bounce (like a lump of clay) dumps all of its kinetic energy into less useful forms, like heat and sound. On the other hand, a ball that does bounce retains a greater proportion of its kinetic energy.

Answer 3

Newton's First and Third Laws of Motion ..... I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. III. For every action there is an equal and opposite reaction. So when a ball hits something - a wall or the ground - there is a reaction. The wall or ground moves (slightly) in the direction the ball is travelling and the ball moves (a lot,in comparison) in the other direction. The "force" which causes this is the same force which moved the ball initially - the throw or the kick which set it in motion.

Answer 4

It depends on the ball really. If the ball is a tennis ball then it would produce less kinetic energy so it would bounce for a while before it stops bouncing, but if it is a Shot (Shot Put in Sports), which is a metal ball, it would produce a lot of kinetic energy when it bounces on the ground, so there would be less potential energy. So it depends on the material of the ball

Answer 5

The ball firstly possess potential energy and when it bounce it acquire kinetic energy and at it's highest point kinetic energy converted into potential energy .

Answer 6

Gravitational Potential Energy from being up high is being converted to Kinetic Energy as the ball bounces.

Answer 7

kinetic energy

Answer 8

balls bounce due to stored kinetic energy

Answer 9

Chemical energy
