Physics of the Tennis Kick Serve

The spin values shown in Fig. 11 refer to the amount of spin generated as the ball comes off the racquet, not the spin after the ball bounces off the court. Despite the fact that the server swings up at the ball in a kick serve, the ball must be projected downward below the horizontal for a good serve.

Get More Spin on Your Table Tennis or Ping Pong Serves

 · The more you brush the ball instead of hitting it solidly, the more of your bat speed will be turned into spin on the ball. So you will generate the most spin when you have a fast moving bat that is skimming the ball, and you will get the least spin when you have a slow moving bat that is hitting through the ball.

Ball mill

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

If you are a low spin player like I am, you need ball speed to keep the ball in the air. When I lose 11 mph of speed coming off the driver’s face, the ball struggles to climb in the air as much (think of it like a rocket running out of fuel), and the total distance is affected quite a bit.

How To Hit Topspin In Tennis by Rolling the Ball | Feel Tennis

How vertical is it depends on the incoming ball (speed, height, falling or rising, spin or slice, etc.) and on what they want with their ball (fast, high, lots of spin or not, short or long, etc.). So there are many variables that determine how vertical the racquet face is and at what angle we swing at the ball.

Golf ball cover: The cover of the golf ball can comprise either Surlyn to produce higher spin than the 2-piece construction, or Urethane to provide maximum spin performance. Surlyn cover: A Surlyn cover for a 3-piece construction needs to be lower modulus than the cover of the 2-piece construction to increase the ball spin but still be stiff enough to provide ball velocity.

How Far Should I Hit My 7 Iron?

Spin rate has nothing to do with the effort that the person is providing – the ball cannot see that. It is has everything to do with what the club and ball are doing through impact. So, to answer your question – no, the fact I am swinging below my full speed has nothing to do with it (unless it changes a parameter at impact) – which I kept constant for this test.
