## How does the ball affect its bounce?

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!

How does a ball bounce physics?

When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. The ball slows down, deforms temporarily and shoots back up. The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat.

What factors affect bounce efficiency?

What factors affect the efficiency of the bounce of a ball?

• The height at which the ball is dropped. We would use a meter rule to measure where we dropped the ball from and then what peak it reached whilst bouncing.
• The surface onto which it is dropped.
• The type of ball used.

### What environmental factors affect the bounce 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 makes balls 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.

How will drop height affect the number of bounces?

The higher the drop, the higher the rebound height, obviously. However, the higher the drop, the smaller the bounce efficiency also became. For example, a drop from 50cm had a 38 cm rebound whereas a drop from 200cm had a 102cm rebound. That is, the ratio becomes smaller with higher drops.

## Does density affect bounce?

Density does affect the bounce height (to some extent), in particular, due to air drag: the higher the density, the less significant is the effect of air drag.

How does temperature affect bounce of a ball?

This is because the gas molecules inside the ball expand as temperature increases. As the gas molecules expand, their energy increases and they bounce around faster inside the ball. That’s why higher pressure leads to a higher bounce of the ball. Likewise, a lower temperature will lead to a lower pressure.

What force causes things to bounce?

Bouncing: Gravity. Elastic force (ball acts as a spring)

### What are the factors that affect the bounce of a ball?

There are many factors which will affect the bounce of a ball: · The size and shape of the ball · The material the ball is made from · The surface it is bounced on · The weight of the ball For example, a ball dropped on sand would absorb more energy than a ball dropped on a concrete floor. Aim To investigate the bounce of a ball.

What happens when a ball is dropped on the ground?

When a ball is dropped gravity pulls the ball toward the ground, slowing the ball down so that each bounce is shorter and shorter, until eventually the ball stops bouncing. The force of the ball hitting the hard ground puts an equal force back onto the ball, meaning it bounces back up.

What causes a tennis ball to bounce when dropped?

When the ball is dropped from a certain height, depending if the conditions a right, such as type of ball, surface and the starting height, the ball will drop and bounce to a peak lower than the starting height. Then the same will happen from this lower peak, the ball will again fall and will bounce to a lower peak lower than its beginning peak.

## Why does a basketball bounce lower on hard surfaces?

This causes the ball to bounce lower than when it is bounced on hard surfaces like concrete. The higher an object is held, the more potential energy it has (if it is going to be dropped). When that object, such as the basketball, is dropped, its potential energy is converted into kinetic energy.
