Tennis balls particularly the new ones are definitely a great deal. To many fans who have small knowledge about the ball, they might feel, “Well a tennis ball is simply just a ball that is fluffy and round ”, however, most if not all of the pros would most times lookout for the tennis ball that has its fuzz still intact for high-performance shots and ball control. When a tennis ball is designed with the finest rubber with premium woven cotton and other secret components for high-performance play, this is part of the good luck for the player and this is why new fuzzy tennis balls are usually a serious deal for the players.
To mention a short process of how the tennis ball is designed, raw rubber materials are gathered together and melted into hemispherical structures or covering. This covering is gummed together by a very strong bond from the ball. After this process, the tennis ball is blown or inflated with pressurized air to give it a good bounce.
There have been a few discussions on why there is fuzz on a tennis ball and at the end of this guide you should have a good understanding of why there is fuzz on a tennis ball
Now to why there is fuzz on a tennis ball,
Prior to the modern tennis ball, the old ones that existed in the thirteenth century were just pieces of wool rolled together into a compacted ball with leather material as the outer cover. One of their reasons for this design is it would prevent the ball from extreme fly when it is hit real hard.
For the modern tennis ball, however, the fuzzy material designed on a tennis ball (also called the nap), is added after the rubber ball has been manufactured. The fuzz is a textile material that comes from cotton, nylon, and some wool. Two pieces of the fuzz come into play in the design of the tennis ball. And this is the reason for the long curvy white pattern on a tennis ball. The fuzz on a tennis ball is actually the most expensive as well as the most significant part of the tennis ball. It is means a lot to experienced players because of its great impact on the ball’s speed and control during the game. And this is the sole reason why most players take their time in selecting the balls they would use for the game. Many would go as far as stuffing enough of these balls into their pockets all in the name of getting the ones that still have the fuzzy cover very intact.
The fuzz on a tennis ball is definitely there to bestow significant ball control to its players. A tennis ball with just it’s rubber and no fuzzy material on will fly faster when hit roll much faster on the ground losing its bounce and expiration very fast and more importantly making the game and boring and as dangerous to the players involved. However, when the ball is wrapped around the two fuzzy material, the unnecessary smoothness of the rubber ball vanishes, increasing the friction of the ball when hit through the air and as a result gradually reducing the pressure build-up behind the ball and slowing it down gradually. However, the much friction caused between the ball and the air gives it several spins, resulting in higher ball control in the game.
Depending on the player’s choice and shooting power, the players can decide to use the backhand or forehand shot to send their opponent running at different wide directions in the court. When the players make use of the backhand shot, the ball would most likely also make backspins moving clockwise and kicking the air upwards. With a forehand shot, however, the ball tends to make an anticlockwise movement with several topspins kicking the air downwards.
The force common here is the drag force. With professional players hitting the ball around with drag force, the ball slows down drastically during movement in the air to almost about a third of its initial momentum. As a clearer example, a ball moving at about 210 meters per hour will get to its opponent at 70mph. Not only is the speed of the ball limited by the drag force, the moment the ball starts its bounce on the court, it also starts to lose its speed. Also, and definitely, after some hitting and bounces in the game, the ball starts to wear off. It starts to lose its bounce as well as its speed through the air. Players at this point would change the ball to look for a newer one with a tight compact uniform fuzzy material.
There are different types of tennis balls with their peculiar game conditions. They are up to 7 unique types of tennis balls around. These different types of tennis balls are influenced by how thick their fuzz covering is and how much pressure is held in them. And of course, some of the game conditions would cover the type of court (such as the grass or clay) being played on with respect to the tennis ball that is used. Several tennis ball brands are tested yearly in wind tunnels by the ITF to understand the aerodynamics of the ball in improving the design of the ball and the performance of the player in the game.
As to why the tennis ball is green, this should be no other than to emphasize more on the ball visibility so that the audience or the spectators can have an easy focus on the game in knowing where the ball was directed to and where it landed in the court.
The fuzz of a ball is definitely a significant part of the tennis ball because of its major influence on the game. This is why many professional players take their time in selecting the best fuzzy balls combining them with wise ball control and explosive power using them to their advantage as against the inexperienced players who get easily frustrated in the game hitting the balls widely about in the court.
