A tennis ball
A wet tennis ball is a ruined tennis ball. It does not bounce as high. You can dry a tennis ball quickly by hitting it against a chain-link fence repidly for a little while. Once the ball is dry, then you can use it again.
You have to spin or slice the ball hardly, but if you watch the "prince of the tennis'' before, you will know that a ball can't spin that incredible. The ball curved depends on your strength, just spin your hardest!
The standard weight of an official tennis ball is between 56.0 and 59.4 grams. This is defined by the International Tennis Federation. The gravitational strength of Mars is 38% that of Earth's. So a tennis ball would mass between 21.3 and 22.6 grams on Mars.
It is called a swing.
Its called Topspin.

The machines tennis players use to shoot tennis balls are called tennis ball machines. Tennis players also call them ball machines, but a Google search for "ball machine" might bring up machines from different sports.
The little ball on your squash racket is used to absorb the shock when you hit the ball. Once you get your strings changed, though, you no longer need the ball because the strings that you get put on your racket are generally better than the ones that your racket came with. If you take off the little ball with the original strings, you will probably be able to feel a little difference when you hit the ball (it might vibrate a little).
