Topspin is nothing else but the type of rotation given to the ball when it is hit. Using the promotion rotation we will make it rotate clockwise (viewed from the side).
Using topspin in the game
By using topspin in the game we will cause the ball to fall faster onto the court, thus reducing the likelihood of playing too long a strike coming out of the car. In addition, thanks to this, you can place the ball higher above the net, and this in turn will reduce lost points as a result of hitting it.
How does topspin cause such ball behavior?
To better understand the operating principle behind balls played with topspin, it's worth knowing about the Magnus effect . A rotating ball around its own axis creates a thin layer of air around it. The rotating layer of air "revolves" according to the movement of the ball.
Encountering air mass on your way as you move to your opponent's side, it comes to a situation where the air flowing from the bottom of the ball becomes faster and the air that passes the ball from the upper side is slightly slowed down due to the action of opposite forces.
Due to these additional forces, the pressure over the ball will be higher than the lower pressure, which will cause the ball to move according to the rules of physics from higher to lower pressure. Thanks to the use of topspin, the game can be more aggressive and at the same time be quite regular. Most often used by Spanish players on clay courts.
