Tennis Speed: Forehand Speed and Spin Rates of the ATP Stars. For those of you arrived here after clicking the link from our YouTube channel to find out what the exact spin rates are for the 4 forehands and 1 backhand shown on the Federer video clip… Here are Fed’s spin rates to the nearest 100 RPMs without further ado: Forehand #1: 700 RPM Forehand #2: 2,500 RPM Forehand #3: 800 RPM Forehand #4: 3,100 RPM Backhand #1: 1,800 RPM The wide variation in the amount of topspin that Federer can generate on his forehand - a 2,400 RPM variation among the 4 forehands shown on the video - is but one of his many remarkable abilities that he has tapped on the way to 16 Grand Slam singles titles. How he does this, we will discuss in future posts...
Now, if you are curious about BOTH the ball speed AND spin rates for the top ATP players on the forehand, that information – obtained using our own high-speed video footage and custom video analysis software—is listed in the table below. So, how do top player ball speed and spin values compare to players at other levels? Teaching tennis - tennis players - first serve - second serves, forehands. This section is about the physics of tennis and anticipation In consideration of the realities; time and space, movement and distance, force and inertia, and clarity and confusion the superior player must take stock of the whole viewpoint.
The tennis court is 78' x 27' with a net that is 3 1/2' on the sides and 3' at the center. The ball travels between 50 and 110 mph on groundstroke rallies. This allows from the time you hit the ball from the baseline until it is returned by your opponent anywhere from roughly 3.5 seconds to 1.0 seconds. This is all the time you have from the moment you hit the ball until it returns to your racquet. The optimum place to be is in the center of the court at all times in a groundstroke rally. From the center point there is 13.5 ft to each sideline. Anticipation is the ability to speculate and make a judgement on where the ball is to be hit in order to get a jump on it. There is in every trajectory optimum positions to hit the ball. 2.50 seconds 317.75 lf.
Angular velocity - Tennis serving machine--- How does a spinning ball bounce. If want to describe the dynamics of the ball, you need to use the SO(3) matrix which describes the ball's orientation. This is a 3 by 3 matrix whose transpose is its inverse. These may be parametrized by Euler angles, and most of the literature on rigid rotating bodies uses this convention, but I think it is best just to use the matrix entries themselves because Euler angles are hard to work with. The orientation matrix itself has a velocity vector which is described by an antisymmetric matrix. The center of mass motion of the ball, ignoring air, will be a straight parabolic arc in the direction of the original motion, and the spin has no effect.
There is asymmetric air drag on the ball when it is rotating, which will lead the ball to arc its trajectory a little bit, this is a small effect. Given your current spin design, you will make inhuman and unanswerable serves. Reflection of spinning tennis balls Since you keep asking for this, I worked it out. For a shell, like a tennis ball, . Air Cannon Velocity v. Pressure. An Exploration in the Relation Between Pressure and Initial Velocity at a Constant Volume, in Regards to a Compressed Air Gun Made Entirely from Products Purchased at Home Depot Brian Grambow Justin Recore Amelia Sires Period 3A Statement of Problem The purpose of this experiment is to find the relationship between the pressures of the tank to the distance the projectile is shot out of the cannon. Table of Contents Hypothesis Review of Literature Materials Procedure Cannon Construction Procedure ResultsError Research Log Bibliography Return to Research Page Hypothesis TOC If we launch a tennis ball out of an air cannon, then the initial velocity of the tennis ball will increase as we increase the air pressure inside the reservoir.
Review of Literature TOC There are many variables concerning the operation and construction of air cannon. Materials TOC 1. 3 in diameter ABS pipe, measuring 8 ft and 3 ft as two separate pieces 2. Procedure- When Cannon is built for Data Collection TOC 1. 1. 3. The Physics of Ball Spin in Tennis, Topspin and Backspin. The Physics of Ball Spin in Tennis, Topspin and Backspin - A topspin shot is hit by sliding the racquet up and over the ball as it is struck. By dragging the racquet over the ball, the friction between the racquet’s strings and the ball is used to make the ball spin forward, towards the opponent.
The shot dips down after impact and also bounces at an angle lower to the ground than a shot hit with no topspin. As a ball travels towards a player after bouncing, it has natural topspin that is caused by the friction of the tennis court. When hitting a topspin shot, the player is reversing the spin of the ball, which requires more energy. - A backspin shot is hit in the opposite manner, by sliding the racquet underneath the ball as it is struck. . - Sergi Bruguera, is know as a player who utilizes a lot of topspin. . - Examine the 3 different clips of the tennis balls in a wind tunnel at a simulated 120 mph. . - Think of a tennis ball being struck.
