# How High Does A Basketball Bounce?

## Can a basketball bounce on grass?

At least two different surfaces to bounce a basketball on, with at least one hard surface and one soft surface (For example, you could use carpet, concrete, grass, linoleum and a basketball court. The surface needs to be flat and next to a wall or other large perpendicular surface.)

## Does the height you drop a ball from affect how high it bounces?

You‘ve probably noticed that if you drop even the bounciest of tennis balls from a height, it never bounces back higher than where it started. When you drop the ball, gravity pulls it down and it picks up speed. It hits the ground and squashes at the moment of impact.

## How do you calculate how high a ball bounces?

If the first height is h, the second will be f*h, the third f*f*h, the fourth f*f*f*h, and so on. So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on. Try it yourself!

## Does a tennis ball bounce higher than a basketball?

It might seem like this is a physics cheat to have the tennis ball bounce so much higher than it started (and that’s probably why it’s so cool to see it). But in terms of energy, it’s all legitimate. Both the basketball and the tennis ball are moving at the same speed right before they hit the ground.

## Why do balls bounce differently?

The faster an object moves, the higher its kinetic energy. 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!

## Why does a ball stop bouncing?

If you drop the basketball, the force of gravity pulls it down, and as the ball falls, its potential energy is converted to kinetic energy. This is because the basketball had an inelastic collision with the ground. After a few bounces, it stops bouncing completely.

## Do heavier balls bounce higher?

Both balls will fall at a similar speed, but because kinetic energy is proportional to the mass of the object, the heavy ball reaches Earth with more energy. It will not necessarily rebound higher, as it also needs more kinetic energy to reach a specific height again.

## What is the relationship between drop height and bounce height?

The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.

## Is energy conserved when a ball bounces?

Consider the energy. The total energy is constant between bounces if we neglect air friction. We have the kinetic energy of the ball and the potential energy due to gravity. At the top of the bounce, there is no kinetic energy so all the energy is potential.

## Why does a ball bounce higher when dropped higher?

Because the ball is softer than the floor, it does most of the denting and stores most of the energy. When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.

## What factors affect the bounce height of a ball?

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.

## What energy does a bouncing ball have before it is dropped?

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 doesn’t a ball bounce back to its original height?

This elastic potential energy is why the ball is able to bounce, or rebound. After the ball rebounds, the elastic potential energy is transformed into kinetic energy, but it will never possess as much kinetic energy as during its original fall. The ball will never be able to rebound to its original height.

## What forces act on a bouncing ball?

The forces acting on a spinning ball during impact are the force of gravity, the normal force, and the force of friction (which has in general both a ‘translational’ and a ‘rotational’ component).
