Do you mean Tennis balls?

This is what I found

The fuzz slows down the ball in flight, keeps it from bouncing too high, and lets
the racket get a better "grip" on it. A perfectly smooth ball would travel so fast
and bounce so high that the game would be unplayable. Also, with a smooth
ball, it would be much more difficult for the player to control the direction of
the shots.

Makes sense. I also read somewhere that since tennis courts are made of different surfaces, they needed a ball that would be playable on all of them (Grass, clay etc)

this is fun!
