2. Introduction to Science of Football
I choose this topic because I love Football.
I love when you tackle people and run to the touch down.

3. Potential Energy
When the player is standing with a ball in his hand about to throw the ball.

4. Kinetic Energy
When the players run to there touch down with the ball in there hands.

5. Digestive System
The Digestive system digest food to give our body energy.
Everybody needs to use energy to eat. The stomach and liver work together to give our body nutrients. The digestive system helps Football players to get the energy they need to play hard and conseract.

6. Respiratory System
The Respiratory system use the energy to clean the incoming air. And gets oxygen into our body
The body uses oxygen to release the energy and gets rid of carbon dioxide that can be dangerous.
The digestive system helps soccer athletes get the energy they need to play hard!

7. Circulatory System
The circulatory system consists of the heart, blood, and blood vessels. It needs energy to pump the blood throughout the body.
Football players need a strong heart so they can exercise and play good.

8. Excretory System
The excretory system releases water and salt from the body as well as releasing excess heat. Energy is needed to keep this system working. Football players need the excretory system to sweat and cool off their bodies when they play.

9. Muscular System
Muscular system used energy to make our body move around.
Foot ball players need strong muscles to move their legs to run fast.

10. Electric Energy
Electric Energy is continuous flow of electrics charge in closed circuits with good condition such as metal.
The electric energy goes into another form of energy such as light, heat, and sound. Electric energy has made it possible for millions of people to watch professional football on TV.

11. Energy Transformation
There are many kinds of energy transformations that are related to football. For example, a football player can transform the chemical energy in a banana into the mechanical energy needed for running. Running then can produce heat energy causing the football player to get hotter.

12. Conserving Energy
football players can rest up before a game starts so they have more energy for later. On an environmental level, conserving energy lowers pollution. Less pollution allows athletes to breathe in healthier air allowing them to run faster.

13. Newton’s 1st Law of Motion
Newton’s 1st Law says that an object in motion will want to stay in motion and object at rest will want to stay at rest unless acted upon an outside force. Football players and the ball are constantly moving and they will continue to move unless an outside force stops it. one Football player may run into another and therefore stop.

14. Newton’s 2nd Law of Motion
Newton’s 2nd Law says that the greater the force acting on an object, the greater the acceleration, or change in the object’s motion. Therefore, the greater force behind a player the faster he or she will run. Also, the greater force behind a throw higher the ball will go.

15. Newton’s 3rd Law of Motion
Newton’s 3rd Law says that For every action there is an equal and opposite reaction. For example, a football player throwing the ball up will make the ball come down the same amount. Also, the ground is pushing up the same amount the player is pushing down allowing athletes to stand on the field.

16. Machines
One machine that helps the football player is Pro-Lat Machine Lat and a machine bicycle.
Football players also use pulleys when they pull down to lift weights up.

17. Conclusion
Football players would not play right without science. Our body needs energy to play and move. The ball moves and stops a certain way due to Newton’s Laws of Motion. The greater the force,the farther the ball will go. Electrical energy has allowed us to watch football on television.Machines have helped athletes continue to work-out.
