For my science project i have to choose a sport and list five carefully thoughtout ways that Newton's three Laws of Motion are involed in the game i selected.

The sport i have selected is tennis.
i have 3 ways already but i am missing 2 more.

Here are the 3 ways i have already gotten (please tell me if they are good or not or if they need any corrections)

1. The ball keeps going unless the other person hits the ball.

2. The force you hit the ball with.

3. When the ball hits the raquet and raquet goes back and then the raquet hits the ball it goes in the front.

Please help me with the other 2 ways!!!

Here are Newton's 3 Laws of Motion to help you with

Newton's 1st Law: the motion of an object will not change if no unbalanced forces act on it

Newton's 2nd Law: the acceleration of an object depends on its mass and on the force exerted on it

Newton's 3rd Law: whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.

PLEASE PLEASE PLEASE HELP ME!

i need all this help by tomorrow
Thank-You
