4.3.8

Explain how Newton’s three laws of motion apply to sporting activities.

1^st: a soccer ball with stay at rest unless acted on by an outside force (like a player kicking the ball).

2^nd: if you play football and you are a 70kg lineman and you run into a 130kg lineman, you both experience the same amount of force but the smaller lineman will have a greater acceleration out of the collision because of his smaller mass.

3^rd: in tennis, the racket applies a certain amount of force to the tennis ball and the tennis ball applies the same amount of force back to the tennis racket.
