The Physics of Football
Ponca City, We Love You writes "There will be a program on applied physics and real time strategy that you might want to watch on television today. Conservation of momentum during elastic and inelastic collisions is one aspect on which to focus as players tackle their opponents. It is of critical importance that the Patriots bring down New York's huge and powerful running back, 6-foot-4, 265-pound Brandon Jacobs. An average-size NFL defensive back's mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of tackling force. A tackle with half a ton of force may sound like a crippling blow, but the body can handle twice that amount because the player's equipment spreads out the incoming energy, lessening its severity."
Nanotech specialists from Cornell have developed their own take on the "physics" of the Super Bowl by creating the world's smallest trophy, which will be awarded today to a contestant who best explains an aspect of football physics. Just some food for thought while you watch the game on your brand new HD television, though you'd better not be watching it in a church.

You're using her as bait, Master!
If this is what your foot looks like, sir, then I suggest you seek the help of a professional foot doctor. Your egg-feet will scare the children.

I will be conducting a careful study of wave propagation through viscous silicone mediums subject to oscillating vertical acceleration.
Have gnu, will travel.
I'm happy to call it American football if you're okay to call soccer European or world football.
Feel free. Though I should point out that Soccer is a contraction of Association Football, there's a good article here http://en.wikipedia.org/wiki/Football_(soccer)#History_and_development, and predates American Football by some time - the first rules being codified in the 1850s. The less charitable among us followers of more robust codes tend to call it Wendyball or poofball, mainly because of all the falling over, rolling about and crying that goes on.
Then there's Rugby Union (football), which dates from around the same time, and the bastard child Rugby League, aka the thickhead crashball game. Not to mention a whole host of other games including a number of forms played in Ireland (Gaelic) which have been played for close to 700 years.
Compared to all of these games, American Football can be considered something of a johny-come-lately.
So call it Football if you want, but the rest of the world differentiates different styles of football even if you're not aware of their existence.
