The friction force is notĪligned with the ball’s center of mass, thus it creates rotation in theĬounter-clockwise direction, relative to this view. (green) that is angled upward, and a friction force (red) that is angledĭownward, parallel with the face of the racquet. Upon impact, the racquet transfers two forces to the ball: a rebound force The racquet face (blue) moves downward and is angled upward. Figure 1 Diagram showing ball being struck with backspin (left) and topspin (right). This concept is further explained in Figureġ. This action helps aim the ball in the intended direction, and also generates Strings “grab” the ball with the help of the rough fuzz on the ball’s exterior. Racquet is not square with the intended direction of travel. The player swings the racquet in such a way that the face of the Tennis, friction occurs between the ball and the highly tensioned strings of But how is spin generated? ToĪnswer that question, we need to discuss the concept of friction.īetween two objects, and opposes the direction of travel. Spin wins matches and frustrates opponents. Trajectory, only to aggressively dive during the final third of its flight Scrambling across the opposite baseline it can send the ball on an outward The spin they generate can cause the ball to float in theĪir, seemingly defying gravity it can curve the ball sideways, away from the opponent Of tennis, spin allows players to control the flight path of the ball with theįlick of a wrist. Rather than focusing on finesse and precision-two aspects of tennis that are losing importance due to the evolution of the sport-players are now trying to maximize the generation of spin and power. Because racquets are now capable of such feats, tennis players are making adjustments to their game and coaches are teaching different, newer techniques. These materials are capable of producing much more spin and power than their wooden counterparts. Now, all players are equipped with racquets made of newer materials, including graphite, carbon fiber, and fiberglass. In the 1980s, many players still used wooden racquets. Recently, tennis has evolved tremendously, becoming a faster sport with tennis shots increasing in velocity and spin, mainly due to the advancements made in racquet technology. For a player interested inīettering their tennis game by implementing such concepts, an understanding of Limits, it is becoming increasingly important for players to take advantage ofĪspects of the sport like spin and velocity. In racquet technology allowing the tennis ball to be literally stretched to its Like every other sport, tennis is governed by the laws of physics. Tennis, players often appear to hit shots that defy physics, whether it’sĪ groundstroke that resists gravity-floating through the air withīackspin-or a serve that leaves the racquet at an incredible speed. Only for it to curve back toward the pins for a strike? How does OlympicĬhampion figure skater Kristi Yamaguchi increase the speed of her spin just byĪdjusting her posture? The answers to these questions, and many more, lie in This article focuses on the generation of spin on a tennis ball, how to maximize the power of a shot, and finding the “sweet spot” on the racquet.Īthlete and wonder how they are able to perform such an astonishing feat? Howĭoes bowling legend Pete Weber throw the ball dangerously close to the gutter, But it all becomes much simpler when you understand the physics behind tennis. The shots of a professional tennis player may look like magic, seemingly defying the laws of science before your eyes.
