Does the ball lose the same percentage of energy with each bounce or is there an increase or decrease?
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. For example, if a ball bounces 80% of its height on each bounce, then the ball is losing 20% of its energy on each bounce.
Why do bouncy balls bounce so high?
Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. This is because the higher the starting height of the ball, the higher the ball’s potential energy. An object has potential energy because of its position.
Why is a bounce never 100% efficient?
The efficiency of a ball can be calculated by dropping and measuring the height of the bounce. Balls which do not bounce high are less efficient as they have lost energy. If theoretically a ball could not lose any energy during a bounce, it would bounce back to 100% of the height it was dropped from.
Why do lighter balls bounce higher?
During a collision, some of the ball’s energy is converted into heat. When the lighter ball bounces on the heavy ball they exchange energy, and the lighter ball flies off with some of the energy of a heavier ball. It reaches way higher than from the height it was released.
Which tennis ball bounces the highest?
Slazenger balls will bounce heigher than Wilson or Pethaven (reject shop) balls.
Do larger balls bounce higher?
The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.
Why does a tennis ball bounces more at hills than in plane?
As g′than the gravity onh the earth’s surface.So,at the hill the ball is less attracted towards ground than in plains. That’s why it bounces more in the hill.

What is the difference between hard court and clay court tennis balls?
Extra-duty balls are designed for matches on outdoor hard courts. The thick felt doesn’t wear away as quickly, which adds to their durability. Clay courts are not as hard on regular-duty balls. Because of a tighter weave and less fluff, regular-duty balls don’t pick up as much of the clay material.
Are Wilson or Penn tennis balls better?
Ratkovich, of Penn, said Penn ATP World Tour and Pro Penn Marathon balls had a higher grade of felt and a stronger rubber core for players with more power and spin. They cost more but last longer. Wilson’s extra-duty tennis balls, introduced in 1960, are the ball of choice for most hardcourt play.
What is the difference between regular duty and extra duty tennis balls?
Hi Margaret, the difference is extra duty is a much thicker felt and is designed for hardcourt play. Regular duty can also be played on Hardcourts but is versatile enough to be played on clay courts. Extra duty will last a tad longer than the regular balls will on a hardcourt.
Why are tennis balls kept in the fridge?
Why are tennis balls kept in the fridge? Because keeping them cold causes their internal air volume to shrink, so that they don’t leak even the slightest bit.
How long do extra duty tennis balls last?
Level of play: recreational or competitive Recreational Tennis: if you’re just playing tennis at a recreational level, a can of pressurised tennis balls could last anywhere from 1-4 weeks, depending on how much you use them. After that time, the balls will begin to lose their pressure and bounce.
Are extra duty tennis balls heavier?

When should you use high altitude tennis balls?
High altitude tennis balls are designed to be used at altitudes above 4,000 feet. As a result of the thinner air, and the pressure difference between the inside of the ball and the air surrounding it, balls generally fly much faster and bounce higher.
Why do Wilson tennis balls have numbers?
Often the balls will have a number on them in addition to the brand name. This helps distinguish one set of balls from another of the same brand on an adjacent court. Tennis balls begin to lose their bounce as soon as the tennis ball can is opened. They can be tested to determine their bounce.
