Physics+of+Football

You are taking your team to football camp. In order to build a winning team, not only do they need to be in optimum physical condition, but they need to understand the physics of the game, specifically the concepts of velocity, acceleration, and force. You are going to have them view some video tapes and analyze these tapes in order to understand the physics of football, and apply these concepts on the field. Brains as well as brawn are important if you want a winning team, and you plan to take yours all the way to the State Championships! First, watch the introductory videos Introductory Video 1media type="file" key=" Pressure Point.flv" width="360" height="270" Introductory Video 2 media type="file" key=" Carnegie Melons.flv" width="360" height="270"

1. How would you describe the meaning of the words ‘speed’ and ‘velocity’? (Write your answer in your lab book) 2. What are typical speeds of football players on the field? (Write your answer in your lab book) By clicking on //Clip 1, Clip 2//, and //Clip 3// below, you can actually calculate the speed of a player by collecting the time as he travels across the football field using the yard lines as the measurement for the distance.

Make a table like the one below and record your data.

3. How fast are they running? (Write your answer in your lab book) Clip 1media type="file" key="Speed clip 1.mov" width="300" height="300" Clip 2 media type="file" key="Speed clip 2.mov" width="300" height="300" Clip 3 media type="file" key="Speed clip 3.mov" width="300" height="300"

5. What do we call a changing velocity? 6. Acceleration can be a. b. c. You can find these on page 321 in the book.




 * The fastest time officially recorded by the NFL was 4.29 seconds by Deion Sanders in 1989, although the NFL did not begin electronic timing until 1990.** In the electronic timing era, the fastest recorded time at the NFL combine was 4.30 seconds by cornerback Tye Hill in 2006.

7. What is force? Force is a push or a pull.

8. Can a player exert a force on himself? Why or why not? Explain. 9. What is Newton's Third Law and how does it apply to football and forces? 10. So, why do some players fall over and others do not? 11. If ___ forces cause acceleration, what kind of force results in an object staying at rest? 12. Using the previous 3 videos, explain balanced and unbalanced forces. 13. Which will keep an object that is moving at a constant velocity, a balanced or unbalanced force? Explain why.
