Tennis
Tennis is an Olympic sport with an interesting background. It originated in England in 1870. The equipment they need is a tennis racket and a big tennis net. Also there are rules, the athletes hit the ball back and forth but if they miss the ball, their opponent gets a point. Olympic Tennis also shows Newton’ Laws.
Newton's first law is very interesting and important for tennis. It says that an object in motion stays in motion and an object at rest stays at rest unless there is an unbalanced force. Balanced and unbalanced forces are seen. A balanced force is when an object is up-right. Unbalanced, for example, is if someone was playing tennis they don't want to have the ball to go flying all over the place. Things that are in tennis that are in motion are the ball when it gets hit by the tennis racket. Things that are at rest are standing still when waiting for the game of tennis. These are all the details of Newton's first law of motion.
Newton's 2nd law is seen a lot in tennis. Newton’s second law says that the greater the mass of an object, the more force is needed to accelerate. Acceleration is seen when the tennis racket moves faster and the tennis ball accelerates to the other tennis racket. Force in tennis is when the player pushes the ball with the tennis racket. When the tennis players hit the tennis ball with more force, the tennis ball will accelerate more and go faster and farther. An example of mass is that the tennis racket has more mass than the ball. There is newton's 3d law also in tennis.
Newton’s 3rd Law is seen in tennis in several ways. Every action has an equal and opposite reaction. An action is a motion or an act. A reaction is something after an action. When someone puts their foot backwards, Newton's 3rd Law comes in and their body goes forward. When the ball is coming towards the athlete, the tennis racket hits it and the tennis ball goes in the opposite direction. These are Newton's 3 Laws in Olympic tennis.
