Physics in Football
By Mike Jacobson

​ ​The Esential Question:
How do Newton's Laws of Motion affect Football?


In my research, i will talk about the Physics of Football, it is not a in depth explanation of the Physics of Football. But it is a quick over view. Hope you enjoy.

The Research:
When you play football you are using physics. When you throw the football you make adjustments for all factors, for instance, distance, height, wind, and weight of the ball. The farther away your friend is the harder you through the football. Or the steeper the angle you through the higher the ball will go. Newton’s Laws of Motion, apply to football in many ways, like kicking a football, tackling the other players, and throwing a football. Here is my explanation of each law affecting football.

Newton's First Law of Motion says that when something is motion, it will stay in motion until acted apon by a force, and when something is at rest it will stay at rest till a force acts apon it. To apply that law to Football, if someone is runing they will stay in motion unless a force acts apon it, like the other player tackling them. when the player hits the other player he would then be the unbalanced force, and he would stop. But in the absence of a player then the ground would be the unbalanced force, and you would stop.

Newtons's Second Law of Motion says that when you throw the football it will accelerate in that direction and if you throw the football twice as hard it will go twice as fast, and the bigger the ball the more mass the football has, so the slower acceleration the football will have. So when you throw a Football to another player, you have to acount all factors to get the complete pass. You have to know how fast your player is and how far to throw the football, and if you get this just right you might get a touchdown.

Last but not least, Newtons's Third Law of Motion says that when an object hits the ground it bounces because for when an object hits the ground it has a equal and oppisite reaction to make the object go up, like when you push against the ground the ground will push against you. so when the football hits the it would bounce due to the ground having a equal and opposite reaction. But this law didn't apply when the Miami Dolphins punted to the Pittsburg Steelers and it stuck in the mud when it landed. Follow the link to see the video. http://ballhype.com/video/asdfa_1/

Now when you combine all of the Laws of Motion together you get a great thing called Football. When a player throws a football it will accelerate and the player would catch it, and cause a equal and opposite reaction, then after catching the football he would run the ball. If another player tackled him he would have a force acting on him so that he will come to rest and not stay in motion. That is how the Laws of Motion affect Football.
