Hey Everyone
As we all eat good food and watch a great Monday Night Football game, shouldn't we know how physics plays a roll in football. Here is a ESPN sports science clip with one of the best QBs in the league, Drew Brees. Everyone comment and let us know who your favorite NFL team is. Some trash talking allowed!

    My favorite NFL team is the Pittsburgh Steelers, and yes they are the best.

    This question may be stupid but do wavelike Motions (sound waves) performed by the audience in a stadium have any affect on the spiral or travel of the football to its target???

    I'm not a huge NFL fan but I guess I'm a Jags fan since I live in Jacksonville. How ever in college football besides our beloved JU Dolphins, I'm a huge FSU fan! GO NOLES!!!

    We will neglect sound waves for now.......go gators Gibbs!

    Cruz, in my perspective I believe that in a dome shaped arena that the sound created by the crowd would have almost no affect on the football being thrown. The crowd would have to be creating sound simultaneously to create a wave that would even have a chance at affecting the football being thrown (like a lazier beam of sound waves pointed at the football). The air is a medium that the sound waves travel through but have you ever experienced a sound wave physically pushing you? No. Just like at a concert you can feel the pulse of the music (sound waves from the speakers) hit you especially when your standing right next to it, and vibrate in your ear, but it never physically pushes you back. It would take a great amount of sound waves if any to affect the motion of the ball through the air.

    I hope This somewhat answered you question, or gave you a better understanding of sound waves. (You will learn all about this in Ship Systems Junior Year.)

    I agree with Elamon. Sound waves are very small, on the atomic level, and should have no effect on the movement of the ball. I'm from Tampa Bay so Bucs all the way!

    I forgot to mention my favorite team... Baltimore Ravens and Indianapolis Colts! I'm from Indiana so of course the colts are one of my favorite teams. :)

    Cruz, your question reminded of the movie Hulk. There is scene where the military has engineered some futuristic weapon using sound waves to destroy or slow down the Hulk. I think it is important to realize that all sound is, is the compression and decompression of molecules in a medium. These molecules are MOVING and I believe, in theory, could have a physical affect on an object. However, the energy needed to produce object moving sound waves would be way more than 50,000 screaming fans could produce. Also, the sound waves would have to be focused and getting 50,000 drunk fans to do anything in unison is like the Dolphins going to the Super Bowl this year. It just a'int going to happen.

    I've realized that the spinning motion of a football is a lot like the spin of a bullet caused by the rifling of a barrel. How does that motion make it fly more accurate as opposed to no spin?

    I never realized that a football would need to wobble to make an accurate hit on its target, that was really cool to see. I'm not much of a football fan but if i had to choose...GO GATORS!

    Bosanko, I'm no expert at throwing a football as I play defense, but I believe that throwing the football in a spiral helps lessen the drag created on the ball as it is thrown by making it more aerodynamic. I wonder if they can use the info they got from the ball, if they can calculate the formula for the perfect pass, so that the average person could throw it.

    My team used to be the Jags, but since they fired Garrard, go Lions, my pre-season playoff pick.

    Cruz does pose an interesting question. I would say that fans at a football game would not be able to have any affect on the trajectory of a thrown football. However, could some other type of sound wave affect on the football, depending on intensity, frequency, and amplitude. For instance, you can shatter glass with a high pitched scream in the movies haha.

    I am also a Bucs fan. Cannot wait for Monday night football this week to watch them whip up on the Manningless Colts.
