Why do tennis balls have fuzz?

It actually makes them less aerodynamic, not more, for the reasons listed above.

They are possibly animated GIFs - a type of file which can contain a number of images which show in turn in the same place, giving the illusion of movement.\n\nThere are a number of software packages which can create animated gifs.  It's not really difficult and there is even free software which will help you make them.\n\nIn Yahoo Messenger and MSN Messenger, they are just as described above (MSN uses some other kind of file type, though).\n\nErrr ... What has this to do with TENNIS????

The dimples on a golf ball are there for aerodynamics.  Believe it or not, the dimpled ball has less aerodynamic drag than a smooth one would have, and therefore will carry further.  This is a matter of boundary layer dynamics and somewhat involved, but in short, the dimples force the fluid boundary layer to be turbulent (as opposed to laminar flow) and thereby stay attached to the flying body (the golf ball) which reduces drag.  Make sense?

I don't know about tennis, but it's a common TEENAGE thing, period.  Make sure to wash, maybe using acne soap - if that doesn't help, go to your doctor and ask for something stronger.

When you rub your wet finger over the rim, you're vibrating the rim. Sound is just vibration of air, so if the resonant frequency of the glass is right, it will make a clear tone.

You must remember that the Davis Cup has a very rich history, almost as old as Wimbeldon and older than any other tennis event. I'm sure the term 'rubber' has meaning behind it, but I believe it was simply termed so since the tennis balls they played with back then were made of only rubber (no felt).

It's like cracking your knuckles. It's cardon dioxide released from your joints. Totally harmless.

That depends on your mouse. If you still have one of those with the balls, then the mouse pad is good so that little ball doesn't get as dirty. Noticed, I said "not as dirty" because it sitll gets fuzzys in there. \nIf you have an optical mouse, you don't really need a mouse pad. I have an optical and have never used a pad for it. It has been working for a few years and never had a problem with it.

I'm not sure to what extend should I answer this. But just what I have in mind and I think might be related. \n-The molecules within the ball are closely packed together (they interact with one another) ; and this what gives solid their firm/fixed shape.\n-The energy of the molecules is low compared to energy of molecules of liquid or gas.The molecules basically stay fixed on their position and vibrate with minimum amplitude.\n\nThat's mostly about physics for ball. I'll add more if I remember more. Cheers

Hey, that's a great question. I'm a member of the USRSA, or the United States Racquet Stringers Association. I'm not sure if you're aware, but racquet stringers are an important part of a professional's game. Michael Chang, for instance, was such a fanatic about his sticks that only one man was able to string and regrip them. Hehe. But back to the question at hand...\n\nStrings should really be replaced at least once a year for recreational players. The synthetic materials used to make strings lose most of their elasticity rather quickly (that's why the obsessive pros store their newly strung racquets in coolers; you may have noticed a pro pulling their racquets out of a cooler, or even putting their racquets into the court-side beverage cooler before matches. Now you know why). Anyway, I can't remember the statistics off the top of my head, but if I'm not mistaken, a week after a racquet is restrung it has already lost 60% of its strings elasticity. What does this mean to you as a player? This leads to significant control loss, meaning that you have a smaller margin for error in your game. Another reason to restring your racquet is that old strings can lead to arm and elbow discomfort. When strings are elastic, they absorb more energy from the contact with the ball, however, the energy that the strings can't absorb it sends down the throat of the racquet, to the grip and into your arm.\n\nI'll make a nice little list to summarize things in an easy-to-digest manner:\n\nHow to know when it's time to restring:\n1. Your strings are old. If you only play once or twice a month, then I suggest restringing annually. However, if you play at least once a week, you'll probably want to restring twice and even three times per year (depending on what kind of string you use--synthetic gut strings should be restrung more often because they lose their elasticity so quickly).\n2. Your strings are notched. You're not going to find a better sign. If your strings have worn notches into each other, then it's probably time to drop your racquet off at the stringers'.\n3. If your strings are fraying. This can really depend on the type of string that you use. If your strings are old and you notice the outer layer is peeling off and fraying, then it's probably time to put some news strings on your racquet.\n\nSome people will try and say that you can "feel" your strings being loose by pushing on them with your hands, but my opinion is that most people couldn't tell the difference between a newly-strung racquet at 60 lbs and a racquet strung a year ago at 65 lbs (but whose strings have lost their elasticity and are more like 45 to 50 lbs now). Maybe I'm wrong, but I sure can't definitively tell the difference, and I'm a racquet stringer. That's why we invest in machines to read the tension on the strings.\n\nI'd also like to give you some tips for your restringing. Conventional wisdom says that the tighter your strings are the more control you'll have, and the looser they are the more power you'll have (within reason, of course). Even though this may seem counter-intuitive, we say this because the trajectory of a ball was recorded with a high-speed camera and found that when a racquet is strung at a higher tension, the ball stays longer on the stringbed, thus giving the player more time to "control" its trajectory as it leaves your racquet. Bjorn Borg strung his racquets so tight that during the night at his house, you'd often hear the twang of his strings snapping. This kind of control has its tradeoffs, however. A tighter stringbed is pretty hard on your arm and elbow. If you already have arm and elbow problems/sensitivity, then you'll probably want to string your racquet near the lower end of the range.\n\nAnyway, I hope that this was helpful for you. If you have any questions, don't hesitate to drop me a line.\n\nIn respons

Yes it is used to help control the speed of the ball. If you are on Cement there is more fuzz to slow the ball down. If on grass there is less to give more ball speed.

Around 56g-58g.\n\nA tennis ball is hollow and composed of inflated rubber, covered with a fabric which must be uniform. Its between 2 1/2 and 2 5/8 inches (6.35 and 6.67 cm) in diameter and weighs between 2 and 2 1/16 ounces (57.7 and 58.5 grams). Yellow and white balls are used in competition. When dropped on concrete from a height of 100 inches (2.5 meters), they must bounce upward from 53 to 56 inches (135 to 147 centimeters). The serve is the most important stroke in tennis.\n\nLitell, Mifflin. Integrated Mathematics. Evanston, IL: 1995.

All baseballs are mudded up before the game and are rubbed to be a similar color. Baseballs like all other products can have defects. Most balls that are rejected are because of a defect in the leather or consistency in the stitch. Pitchers like the ball to feel good in the hand. High seams are not bad or disliked by pitchers... they can do more with the ball. But a seam that is uneven, high and low can feel awkward in the hand. Sometimes a ball will be foul tipped into the dirt/gravel and get scuffed badly, umpires check the ball for a smooth surface before they put them back in thier bag. They will unspect every ball that hits the ground and either put it out of play or put it back in thier bag. Pitchers don't always agree that the ball is smooth enough to continue.  Hope this gives you a better understanding!

The fizz is a bunch of bubbles but they dont "explode" because of the static electricity in the hand. When the soda is made, you basically have a shit-load of carbonic acid in it. Carbonic acid is a fairly unstable substace. If you give it any reason, it will conver to carbon dioxide and water. so to keep it the carbonic acid form, the producers put a lot of preassure in the can. As soon as the can is opened a lot of the carbonic acid gets turned into carbon dioxide because you get rid of this preassure. This is evedent becasue you see the bubbles being formed when opening pop. All of the acid is not turned into CO2 though. Some of it get transformed due to the heat in the mouth (this is your fizz). if you stick a finger while pouring the drink, you are heating the pop thus creating the carbondioxide before it actually reaches your mouth. As a result you get to feel less amount of the fizz.

The more pressure a ball has inside it, the less its surface dents during a bounce and the more of its original energy it stores in the compressed air. Air stores and returns energy relatively efficiently during a rapid bounce, so the pressurized ball bounces high. But an underinflated ball dents deeply and its skin flexes inefficiently. Much of the ball's original energy is wasted in heating the bending skin and it doesn't bounce very high. In general, the higher the internal pressure in the ball, the better it will bounce. However, the ball doesn't bounce all by itself when you drop it on a flexible surface. In that case, the surface also dents and is responsible for part of the ball's rebound. If that surface handles energy inefficiently, it may weaken the ball's bounce. For example, if you drop the ball on carpeting, the carpeting will do much of the denting, will receive much of the ball's original energy, and will waste its share as heat. The ball won't rebound well.

The ping pong balls come in a plastic cover (which holds 4 ~ 6 ping pong balls) attached to a card board paper.  In order to stick them toghether manufacturers need to glue plastic cover and paper which is why you smell glue.

I don't know about fuzzy balls(hairy yes), but I normally shave mine before I play tennis. Improves aerodynamics.
