Tennis Rackets One World Essay

Many people know what a tennis racket is, it is used as a extended arm for hitting the tennis ball to the other side of the court (opponents side) to score. During the old days of tennis, about 900 years ago, people have been using their hand as a tennis racket, but it is evolved to pallas then wooden rackets, but the pallas and wooden rackets are really hard to control since it only have a really small racket head size so that it will be harder to hit the sweet spot (center) to have more accuracy on the ball. But after the new/ modern tennis “Graphite racket” was invented, we can now have more control, more accuracy, more spin, more speed for the shots. (GGN. (2011).

A tennis racket is like a extension of your arm, and it is a third class lever, because your shoulder is the pivot point, the arm muscles that you use (biceps and flexor digitorum) are the force, and the contact point between the ball and the racket (most of the time is the sweet spot of the racket because players will try to hit the ball on the sweet spot be make the best quality shot.) is the load. And you can tell that it is a third class lever because the force (muscles) are between the load and the pivot point. Not only how strong your muscles are effect the shots, also the racket and racket...
