How does drop height affect bounce height of a ball?

If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.

Why does a ball bounce higher when dropped higher?

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. … The balls are shown at rest, about to bounce back up.

Does drop height affect bounce efficiency?

The efficiency of a ball can be calculated by dropping and measuring the height of the bounce. The higher the bounce, the more efficient the ball is. Balls which do not bounce high are less efficient as they have lost energy.

Why is the bounce height lower than the drop height?

What usually happens is that the ball is dropped from a certain height, some the energy is lost to heat because of air resistance or friction with the ground. So, after every contact with the ground, the ball bounces to a height slightly lower than the previous height.

Why does a bouncy ball bounce?

When the bouncy ball is stretched, these polymer chains uncoil and straighten. When released, the chains coil back up again. This makes the material stretchy and bouncy. When your ball bounces, it is squishing when it hits the ground, then un-squishing as it bounces back up.

How does a ball bounce?

Rubber is made from long-chain polymer molecules. … Atomic motions within the rubber molecules then return them toward their original, tangled shape. Much of the energy of the ball’s downward motion becomes upward motion as the ball returns to its original shape and bounces into the air.

Why do balls bounce differently?

This is because the higher the starting height of the ball, the higher the ball’s potential 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 bounce lower?

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. … A well-inflated ball bounces better because it has more air inside.

How does the mass of a ball affect its bounce?

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 don t the balls bounce back to their original height?

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 bounce lower each time momentum?

Since the height to which the ball will bounce is directly proportional to its energy (barring effects of air friction), with a coefficient of restitution of less than one the ball will bounce less and less high.

How high does a tennis ball bounce when dropped?

According to the ITF rules a “valid” tennis ball should bounce to between 135 cm and 147 cm when dropped on a concrete floor from a height of 254 cm (53-57 in from 100 in). This means that the ball should reach between 53% and 57% of the drop height when bouncing.

What happens to a ball when it is dropped?

When you drop the ball, it gains ‘kinetic’ energy (the energy of motion) and loses its potential energy. When the two balls are dropped at the same time, they hit each other (collide) just after they hit the ground, and a lot of the kinetic energy in the larger ball is transferred to the smaller ball.
