Using tennis describe your sport using all of newton's three laws?

Can you name his laws and what the laws mean? That should help you discuss this further.

I'll start with the first one for you.

Newton's first law is the law of Inertia, that an object in motion will stay in motion and an object at rest will stay at rest unless a net force acts upon it. This merely means that an object in motion will travel in that motion until some force stops it, and an object whose speed is 0 will remain 0 until some force causes it to accelerate.

Using tennis describe your sport useing all of newton's three laws?

First law definition: Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.

Example using tennis: The tennis ball will keep moving in the direction it was hit, until the opponent hits the ball back.

Second law definition: The force applied to a body produces a proportional acceleration. The equation F=ma (where F is Net Force, m is mass, and a is acceleration) shows this proportion.

Example using tennis: When lightly hitting the ball with the racket, the ball moves very slowly. If the force used to hit the ball with the racket is increased, the acceleration will increase proportionally.

Third law definition: For every action there is an equal and opposite reaction.

Example using tennis: When hitting a tennis ball, there is a recoil upon contact.
