Does An Old Fencing Ball Bounce Differently Than A Fresh Tennis Ball

The equipment in basketball for example has been altered, such as the basketball itself. It used to be built the same as a soccer ball. However, today, it has evolved into so much more and also is equipped with better grip. This allows players to shoot better and perform their best. The better grip of the basketball is due to the two interlocking cross-shaped panels and has microfiber material (Porter). Technology has also improved the way athletes train. This is for all different types of sports, which includes tennis. In tennis, they have made racquets that help people who are trying to improve their game. The racquets are equipped with sensors that tell the player specific statistics. These include the speed and spin of the ball at which the player hits the ball (“Tennis Pushes the Technology Limits”). Modern advanced racquets help players in other ways as well, but it has allowed tennis players to see what they are doing wrong and correct it.

The solutions are 0% sucrose, 10% sucrose, 20% sucrose, 30% sucrose, 40% sucrose and an unknown sucrose concentration. We then weighed each egg separately to the nearest gram in order to have an initial starting weight to compare to the results throughout our experiment being conducted. The eggs were then placed in each beaker for 12 intervals at a time. After every 12 minutes the eggs were taken out and weighed to see if the weight of the egg changed. With a total of five intervals (12, 24, 36, 48, 60) the steps were repeated till the egg had reached the total time of 60 minutes. The changes in weight of the eggs were then added into a data table showing the weight of the chicken eggs in grams vs. the time in minutes. In a second data table the weight changes (g) vs. time (min.) between the eggs were taken and used the difference from each time and subtracted it from the initial

This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied. In the process of conducting the research, the student will learn that atmospheric pressure may also affect how far the ball will travel. The student will learn about the relationship between air pressure and friction: the lower the friction, the farther the ball will go. The student will learn about concepts like air pressure, gravitational force, compression and expansion of air molecules, potential energy and kinetic energy. This science fair experiment

Tennis is a game of speed and reflex. It uses a lot of muscle memory. You need to be able to move quickly and effectively to reach the ball quickly and hit it. Thus it takes quick reaction time and reflexes to play at higher levels. Tennis drills and practices train your muscles to react faster, smoothly and naturally. During fast volley bouts your muscles often react

1. The ball has potential energy while momentarily at rest at the top of the path.

Your group of 2 will be given 3 balls (a tennis ball, golf ball, and a ping pong ball).

A normal tennis ball has a rubber core occupied with a gas that is composed of unorganized molecules or atoms that move around freely. Molecules of a gas can effortlessly expand and contract. When the ball hits the ground, the force causes the ball’s bottom surface in, and the gas in the core constricts. The gas then springs up when the ball becomes its usual shape, causing the tennis ball to bounce up.

Balls back then were not like the tennis balls we know today. The balls were made of wood and the players would hit the ball into the wall with their bare hands until eventually it got so painful that they eventually incorporated leather gloves to take some of the pain away.

Racquetball is played on a rectangular indoor court with four side walls and a ceiling. The courts are designed so that the ball can bounce off any surface and still be in play, yet it is in a confined area so you don't have to run to cover too much territory.

Moving along, to the second experiment, “How does force affect your game?” concludes that using a 10 pound ball applying strong force provides a velocity (m/s) of 3.2, a result of 25 (J) for the kinetic energy, and 5 bowling points

This confirms what the literature has found as well. The jump serve is more likely to have a decreased flight time, an increased ball velocity and a flatter projection angle. My hypothesis of which serve would be considered better was confirmed, but I was surprised at the minimal difference of each factor between each serve. I assumed that each factor would be significantly different between the two serves. Based on my results, I can confirm that the jump serve is the better volleyball serve in a competition setting. The reduced flight time allows competitors less time to react to the ball, the increased ball velocity makes it more difficult to handle and control and the flatter projection angle makes it more difficult to pass. Therefore, the jump serve is more likely to earn points in a competition

1. What is your question? Which ball will hit the hardwood floor the fastest the medium foam ball or the small rubber ball? 2. What assumptions do you need to make to try to answer the question? (Assumptions are things you don't know, but might suspect.

In the sport of tennis, there are two basic major components, the racket and the ball. The most important aspect of tennis that is practiced, is the ball hitting the racket in the most effective way. There is a large amount of physics involved even with the racket and the ball on their own, but the two in action create a wide spectrum of physics principles needed to explain how the action and reaction occurs.

There has been no greater impact on the game of tennis then the invention of the carbon fiber composite racket. It pretty much changed the game overnight. Before the introduction of these new rackets tennis players were using wooden rackets. These wooden rackets had been developed in many ways including the addition of lamenting them so as to increase their "stiffness and strength"(Jenkins par. 2). The biggest problem with them were that they were prone to warping due to contact with moisture and when a racket became warped it would significantly decrease its performance ability. Carbon fiber rackets eliminated this problem and moisture had no effect on these rackets. This made the rackets much more durable as well as light weight meaning a player could play more effortlessly than ever before.

Two different exercise groups were compared to see if velocity and accuracy of the tennis serve improved following a six-week exercise programme. Results of this study did not demonstrate a significant change in velocity and accuracy between pre-test and post-test data. However, the whole-body exercise group did show a significant improvement in velocity compared with the scapular stabilising exercise group. This highlights how the use of the LEX in the kinetic chain of the serve can influence the velocity more than solely
