- HEY! Do you want to do play tennis today?
- Hi! Sure, will meet you after school.
- Ready?
- Yeah
- Did you know, Newton’s first law states that an object at rest stays at rest and an object in motion stays in motion at the same speed, with the same direction unless acted upon by an unbalanced force. Using a tennis racket to strike a tennis ball is a prime example of unbalanced force acting upon an object in motion. Once the ball is struck it flies over the net before being pulled down towards the ground by gravitational pull. If it weren’t for gravity’s existence, the tennis ball would continue to fly in a straight line forever.
- Yaa, Newton’s second law suggests that force is equal to mass times acceleration. A serve illustrates the equation that Newton was speaking about. Take the weight of a tennis player’s racket and multiply it by the speed at which a player swings their racquet and we will get the total amount of force that was exerted by the tennis racket onto the ball.
- Yes, Newton’s third law suggested that for every action there is an equal and opposite reaction. Whenever a tennis player strikes a ball the force of the racquet striking the ball and the force of the ball striking the racquet both act upon each other.
- Yes, During a serve, kinetic energy is stored in the form of motion as the ball travels through the air. The friction between the ball and the racquet’s strings is responsible for causing the ball to spin forward.
- Every olympic sport has science behind it which makes it more interesting.
- Yaa, that' s true . Lets go home. Its late my parents must be waiting.
- Yeah, I should also get going, BYE
- Yeah, BYE
