They have fuzz on them so the air the ball is traveling through can grip the ball to enhance the spin on the ball. ex. To move it farther (backspin) or to make it drop (topspin) or to make it curve to the side (sidespin). The fuzz also allows the ball to have better interaction with the surface, the air and the racquet. As the ball speed increases the fuzz filaments lay down on the ball and the fuzz drag declines.
The tennis ball cover is rough but not like sandpaper. Looking closely at the felt you can see that air flows through those raised fabric filaments - better known as fuzz. So the surface of a tennis ball is a "porous surface." It's more like dealing with the wind blowing through leaves on a tree and just as complicated. The fuzz filaments act like tiny cylinders each having their own drag component. In addition to the skin friction drag from the cover itself, drag is created from the airflow over these fuzz fibers interacting with all the other fibers behind it.
Its more of a fuzz then hair. Its so the strings can grip the ball, giving it spin.
its called fuzz if you play with it a lot it will show up
A tennis ball is fuzzy because the fuzz from the ball actually decreases the ball's speed while in flight. The fuzz also prevents the ball from bouncing too high.
It's obviously fuzzy from constant hard-hitting of the ball.
Tennis balls tend to shed off on to courts.
wont slide on rachet
because Brazilian waxing hurts too much
Small denier nylon filament
course it does
You could use the hook section of Velcro and tear the fuzz up on one ball and conduct spin and bounce comparisons with a regular ball.
I don't believe there's any correct terminology. I think people know what you mean when you say fuzz.
My baby mouse has a tennis ball cut in half and a whole cut out so he can get out and some fuzz from a stuffed animal. I put the tennis ball on the fuzz. He might burrow in it so don't worry if you don't see him.
Water doesn't enter any tennis ball that's in good condition and hasn't been punctured, so in that sense, every undamaged tennis ball is waterproof. But the fuzz on the outside can sure get soaked. I have made a waterproof tennis ball that makes even the fuzz keep dry. It is pure awesome.
The more fuzz, the less bounce. The less fuzzy, the higher the bounce.
It's a tie between Wilson U.S. Open or Penn. Either is sure to cut down on fuzz. But the Wilson's get worn out easily but are ah-mazing balls when they're alive!
The fuzz increases the drag of ai over the surface allowing the spin imparted on the ball by the player to translate into motion in the direction of the spin. Hence you can hit a curve ball.
The fuzziness of the ball gets grip from the surface and the felt rubs the surface of the court and thus causes friction. The denser the felt, the more friction and grip. The fuzz helps improve the friction, which makes spin more important in a match. It makes the ball slower, and in turn the rallies will be slower. This is why in most ATP tennis tournaments, the balls are changed every seven to nine games.
