A player must have control of his/her racket when he/she hits the ball. That means, a player can’t drop or throw a racket to hit the ball, and the player loses the point if the ball touches a dropped or thrown racket.
Correspondingly, how do you catch a tennis ball with a racket?
When a tennis player serves a tennis ball, the serve can reach speeds over 124 mph (200 km/h).
Also, is a double hit in tennis legal?
f is that a player must “deliberately” touch the ball with the racquet more than once a shot. As USTA Comment 24.5 states, “Only when there is a deliberate ‘second push’ does the shot become illegal.” The rule continues to clarify that: “Two hits occurring during a single continuous swing are not deemed a double hit.”
Can you hit the ball with your hand in tennis?
Yes, you can use your hand to hit the ball, but only if it is your racket hand and below the wrist. A quote of the rules state: It is considered legal to hit the ball with your fingers, or with your racket hand below the wrist, or even any part of the bat.
How long is a tennis ball in contact with the racket?
6 milliseconds
Why does a tennis ball not slow down very quickly when hit?
Why does a tennis ball not slow down very quickly when hit? The under-inflated ball encounters somewhat less air resistance (air drag). It would therefore not slow down as quickly and would be able to travel further.
What is kinetic energy generally lost as when real life cue balls collide?
An extremely small amount of kinetic energy is lost in this collision. An example of an elastic collision that’s common in everyday life is the collision of pool balls. When the balls collide, they bounce off of each other, but they lose some kinetic energy to sound energy and heat energy.
What is the average contact force between ball and racket?
The huge force exerted by the bat on the ball causes severe distortion of the ball as it is hit. So, during the bat-ball collision, an average force of roughly two tons acts during the 0.7 millisecond contact time, with a peak force of about four tons.
