## What height should the ball bounce to?

Thus a typical ball bounces to 60% of its original height because it stores and returns 60% of the energy it had before the bounce. 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 makes a ball bounce higher?

As the ball is dropped and gravity forces it downward, the velocity of the ball increases because of the accelerating effects of gravity. The ball falls through the air, converting stored energy to the energy of motion, and impacts the floor, bouncing higher.

### What is bounce height?

The “height of bounce” is the distance from the table top to the bottom of the ball on the first bounce. (Practice a few times to make an accurate observation. Record the height that the ball bounced on the data table.

Does ball size affect bounce height?

For example: the amount of air, material, shape, and the spikes. when the ball hits the ground and this percentage should remain constant. The size of the ball effects the height of the first bounce. In all three trials, we found that the larger ball bounced higher than the smaller one.

#### Which ball bounces higher when dropped together?

Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.

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.

## Can a ball bounce forever?

The law of conservation of energy implies that a bouncing ball will bounce forever. When you drop it on the floor, it changes some of its energy into other forms, such as heat, each time it hits the floor.

What type of balls bounce the highest?

When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. When the rubber ball hits the ground it gets compressed, or squished, and because it is very elastic, it quickly returns to its original shape.

### How many times does a ball bounce?

In an idealized situation with a fixed coefficient of restitution between 0 and 1, a ball bounces an infinite number of times in a finite amount of time and travels a finite abount of total distance, with the frequency of bounces approaching infinity as the time approaches the limit of time based on the initial …

Does mass affect bounce height?

If the mass of the ball increases than the height the ball bounces will increase because the more mass an object has the more energy that gets build up when the ball gets released and makes the ball go higher.

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

Did you find that a single ball never bounced back to the height at which you released it, regardless of the ball you used? During a collision, some of the ball’s energy is converted into heat. As no energy is added to the ball, the ball bounces back with less kinetic energy and cannot reach quite the same height.

Why does a ball not bounce back to its original height?

## How tall should the first bounce of a tennis ball be?

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 f depend on the height? (it shouldn’t much, but it might..) Try it for different balls! which type of ball bounces the most? which kind of ball bounces the most?

What does the height of a bounce mean?

For multiple bounces, it’s just like dropping the ball again from a reduced height. 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.

### How do you calculate how high a super ball can bounce?

Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity.

How to measure the bounciness of a soccer ball?

Paint each of the balls with poster paint in a circle around the ball so that you can hold the ball on both sides to bounce it. Stand 1 meter from the wall. Measure this distance using a meterstick. Bounce each ball toward the wall without using any of your own force.
