How high will it bounce rebound ratios?
Tennis balls: Must rebound approximately 111cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120cm when dropped form 200cm onto a steel plate. Basketballs: Must rebound approximately 53.5 inches when dropped from 72 inches onto a wooden floor.
How can you tell how high a ball bounces?
Determine how high the ball rebounds on its first bounce. To be consistent, again measure to the bottom of the ball. One group member should carefully release the ball and others should determine the height of the rebound. If the agreement between the rebound measurements is not good, repeat the measurement.
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.
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.
What energy does a bouncing ball have before it is dropped?
potential energy
What type of ball bounces the highest?
rubber bouncy ball
Does a ball of glass bounce higher than rubber?
It’s true! When you drop a ball on a surface, it compresses and squashes slightly, before snapping back to its original shape. In addition, a solid glass ball will also bounce higher than a rubber ball, but then the trick is finding a surface hard enough to make the ball bounce, but not hard enough to break it!
Why will a ball of glass bounce higher than rubber?
Why Glass and Steel Bounce Better Than Rubber When a rubber ball hits a surface, it compresses and deforms before returning to its original shape. Quite a lot of energy is lost in this process. Most of the energy of the impact returns to the glass.
Why do glass spheres not shatter?
Provided that you have chosen the surface and the impact speed carefully so that the glass ball does not shatter, the glass ball ought to bounce quite well. If it rings a long time, then the vibrating glass does not dissipate energy very much when strained in alternating directions.
How high should a table tennis ball bounce?
23 cm
Why do table tennis balls bounce so high?
Balls, including ping pong balls, bounce after they hit a solid surface because an equal and opposite force from the surface pushes them back upward. Ping pong balls have a tendency to bounce well because they’re made out of a plastic material that is especially stiff and springy.
Does a tennis ball bounce higher than a ping pong ball?
(In technical terms it is called an ‘inelastic collision’.) Having less energy, the ball doesn’t bounce as high. That answer works well for a nice bouncy tennis ball.
Why does a tennis ball bounce higher than a basketball?
At the same moment, the tennis ball bounced away from the basketball at twice that speed. As the tennis ball flies up into the air, gravity slows it down, converting all of that kinetic energy into potential energy. And the more potential energy the ball, the higher it will go.
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.
Does mass affect bounce?
Mass affects a ball’s bounce through kinetic energy. The more mass an object has, the more kinetic energy it has when dropped, due to gravity.
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.
Does the size of a bouncy ball affect how high it bounces?
Data. The larger ball will bounce higher than the smaller ball on the first bounce.
Does density affect bounce height?
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 the height of a bouncing ball?
A warmer ball will bounce higher than a cold one. The reason for this is twofold. In a hollow ball, the change in temperature causes a change in air pressure within the ball. The other way in which temperature influences the height a ball bounces is by impacting its elasticity.
Why are Wimbledon tennis balls kept at 68 degrees Fahrenheit?
At warmer temperatures, the gas molecules inside the ball expand making the ball bounce higher. …
Does temperature affect the bounce of a handball?
The temperature of the ball affects the elasticity of the material of the ball. The cold ball does not have much elasticity, and more energy is lost when it collides with the floor, with the result being that it does not bounce as high.
How does temperature affect rubber?
The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
