The Physics of Football

Posted by Soulskill on Sun Feb 03, 2008 11:23 AM
from the mass-times-acceleration-equals-pain dept.
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.

theodp writes "For 200 members of the Immanuel Bible Church and their friends, the annual Super Bowl party is over thanks to the NFL, which explained that airing NFL games at churches on large-screen TV sets violates the NFL copyright. Federal copyright law includes an exemption for sports bars, according to NFL spokesman Brian McCarthy, but churches are out of luck. Churchgoers who aren't averse to a little drinking-and-driving still have the opportunity to see the game together in public on a screen bigger than 55 inches."

      I'd like to point out that this blog is written in American (yes, American, not USian) English. A dialect distinct from the English you may be used to. And in this language football is, in fact, the name of the current subject. Complaining that we use the "wrong" words for things is as silly as complaining that the Spaniards say "juegos" instead of "games". It's a different language. Get over it.

Regarding Slashdot, if your target audience is national, "football" is ok..on the other hand if your target audience is international use "American Football", unless you want to communicate you're ignorant of the biggest sport on earth named with the same sequence of letters, and serve your percentage of international viewers a title which means something different to them.

      Slashdot seems to be very U.S.-centric. Do you have any plans to be more international in your scope?

      Slashdot is U.S.-centric. We readily admit this, and really don't see it as a problem. Slashdot is run by Americans, after all, and the vast majority of our readership is in the U.S. We're certainly not opposed to doing more international stories, but we don't have any formal plans for making that happen. All we can really tell you is that if you're outside the U.S. and you have news, submit it, and if it looks interesting, we'll post it.

        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 [wikipedia.org], 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.
