Why does bouncing ball lose energy?

When a ball hits a wall or surface, it makes a noise, which is a loss of energy from the ball’s bounce. It also will generate some amount of heat, another loss of energy. Friction from the wall will cause energy loss as well as air resistance while the ball travels.

Can energy be lost when bouncing a ball?

Standard textbooks on kinematics show that if an object is launched straight up with speed v, then the maximum height reached will be h = v 2 / (2 g ) so v = √(2 g h ). We see that changing the bounce height from h to R h will change the bounce speed from v to (√ R ) v .

What energy is wasted when bouncing a ball?

Lifting a ball into the air before dropping it gives it a type of energy called ‘potential energy’ – which means the ball has the potential to do some work. When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy.

Why does a ball bounce?

Strange as it may seem, a ball bounces off the floor because the floor pushes it up! When you drop a ball, gravity pulls it toward the floor. The ball gains energy of motion, known as kinetic energy. When the ball hits the floor and stops, that energy has to go somewhere.

Why do balls bounce physics?

When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!

What affects ball bounce?

The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.

Why do balls bounce?

Strange as it may seem, a ball bounces off the floor because the floor pushes it up! The ball gains energy of motion, known as kinetic energy. When the ball hits the floor and stops, that energy has to go somewhere. The energy goes into deforming the ball–from its original round shape to a squashed shape.
