Why does a tennis ball have fuzz?
550602
the fuzz is used to create spin on the  ball when you hit it. Each individual "fuzz" grabs the air as the ball is  spinning causing it to change direction. (left or rite for a slice shot, down for a topspin shot, or backwards for a drop shot)

A tennis ball weighs more than 2 ounces (56.7 grams) but less than 2 1/16 ounces\n\nA wiffle ball weighs two-thirds of an ounce

As the ball hits the ground, its momentum causes its elastic body to compress itself against the ground until enough force had been applied through enough distance to cancel the momentum of the ball and bring it to a stop.  At the instant the ball comes to a stop, it has energy stored in it due to the compression of its body against the ground.  This compressive energy is then released in pressing against the ground, causing the ball to accelerate upward.

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.

There are plenty of reputable tennis ball machines, I have a Model 4 tennis tutor and its great.  However I just don't have the time to use it very often.

My racket face is definately above my shoulder during my backswing.  Its motion path is sort of like a candy cane when it comes in line with the ball and finishes with a sort of twisted figure eight as I wrap the racket around my shoulder and back.  I would presume after looking closely on camera that my stroke does just dip down below the level of the ball as it straightens to come in line with the stroke.  This all happens so fast that you would need to slow the film down to see the actual path precisely

The container is sealed because the air inside is PRESSURIZED (not vacuum sealed as another proposes).Tennis balls are pressurized on the inside to give them the right amount of bounce.  Over time, air leaks out of the rubber surface, causing the ball to lose pressure and become flat.  So, the container is also pressurized to keep the balls from becoming flat over time before you even use them!

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.

I would guess lumps because of thier absorbtion potential. The powder may dissolve in the water and there by change the color, but do not know if it would eliminate the color.

You might wanna clean the inside of it with a couple of q tips and some rubbing alcohol. Twist off the little circle on the bottom of it where the ball rolls and look inside, there's probably some gunk in there.

Tennis racquets are of a somewhat oval shape while racquetball racquet are much shorter and have a flattened top.\n\nPicture of a tennis racquet:\nhttp://www.ideal.co.nz/site/ideal/images/stickandwin/19_Ultra_LT_Tennis_Racket_WITRCS510.jpg\n\nPicture of a racquetball racket:\nhttp://www.racquetworld.com/merchant2/graphics/product_pictures/racquets/triadt170sm.jpg\n\nWhile a tennis racquet could be used in a game of racquetball, a real racquetball racquet should be used if you have any desire to pursure the game any further. \n\nGo ahead and play a game of racquetball with your friend using tennis racquets, but beware that prolonged use of them in a racquetball game could damage them. Racquetballs are much heavier than a tennis ball and could cause frame fractures and/or damage to the strings. \n\nIt's ok to improvise, but use the equipment designed for the game if you do it frequently.\n\nEDIT:In response to the ball part, you can use a tennis ball if you would like, if the place where you go to play allows it. My local YMCA did not allow tennis balls in the raquetball courts. Again, don't use a tennis ball if you are playing with people other than your friends, as a tennis ball would not be allowed on any sort of competitive level.\n\nNot your question, but you shouldn't do the reverse - that is use a raquetball on a tennis court. The surface of a (hard court) tennis court is very rough and would damage the rubber raquetball very quickly.

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).

Its either an angled drop volley off a hard hit ball, or a blistering backhand passing shot where your opponent starts to move but the ball is already by him.

Contact sports seem to lead to spitting and patting of arses. Tennis players, fortunately, are separated by a net, so that can't happen...the patting part, anyway.\n\nAnd spitting isn't allowed on any tennis court that I know of.

Smooth concrete - elastic collision!!!\nThe total kinetic energy of the system remains the same before and after the collision, (though some deformation and loss of kinetic energy takes place).  If you hear any two object colliding, that means that some kinetic energy has been lost to the system.  The ball will transfer some of its kinetic energy into the rubber pad therefore having a significant decrease in speed.  Therefore, the ball will bounce more if dropped on the smooth concrete.
