FC: Physics Behind Soccer Samaantha, Austin and Stefan

1: Many kids around the world love to play sports. The sport we're going to talk about today is soccer.

2: Soccer is a fun sport played with your feet, a ball, and two teams | The goal is for your team to get the ball into the other teams goal. Children around the world play soccer, but not many of them know the physics behind soccer. Some even think soccer isn't very scientific at all.

3: In truth soccer is as scientific as baseball or football. Forces must be applied to play the game right. There also must be certain feet-eye coodination so you can aim the ball toward the goal or a teammate. As you turn the page, we get more and more in depth with the physics behind soccer.

4: First we'll start with the actual mechanics behind kicking the ball. When you kick the ball the force behind your foot will propell the ball forward. Since you put force behind your foot, the force will transfer to the ball and move it forward depending on the strength behind it.

6: Now that we know the physics behind the ball, we start learning how to kick it and how each way affects it. We discovered that 'toe' kicks were the best. That is when you kick with the sides of your toes. When this happens, the force applied creates both an air resistance force as the ball travels in the air and an applied force when you use the force behind your leg to propell the ball forward.

8: Some of the ways we used that didn't work so well were kicking it from the side and on the top of your foot. Half the time the ball wouldn't go the way we wanted it. We believed this happened because the sides of the toes is were the most force is released from, and since it is near the center of the foot, it keeps a straight alignment and the ball would roll were we wanted it to go.

10: The harder we kicked the ball, the farther it traveled. Sometimes, however, object would get in the balls way, hindering it's movement. (See diagram) Here is the information for the three trials we ran. 1. 133 ft in 14.32 seconds (Red) 2. 184ft in 15.23 seconds (Blue) 3. 161ft in 15.13 seconds (Purple) In conclusion, the less objects in the way of the ball the farther it traveled and the more time it took to travel.

12: Back to the Basics Many other things also contribute to the game play. The field, the players, but mostly the ball. If the ball is not aired up right then it wont have aenough spring force when kicked to be propelled forward. So players must make sure the ball is aired up right before playing.

14: In the end, soccer really is all about how you hit the ball, how hard, and were. Each force must be carefully applied in a split second, so when playing soccer you must be on youir toes. We hope you have learned something from our presentation. Have fun playing a game soon.
