Its Football Time

As we all know, its two weeks into the NFL season (how bout the 2-0 (soon to be 2-1) Bills?) and watching two games of football has been fun. But it got me thinking about some of the physics of football.

As we all know, defense is based on being able to tackle the offensive player before the move the ball down the field (there you go non-football fans i just explained the game to you), and the harder you hit, the better. But the NFL has been recently cracking down on certain hits, and for a good reason. Last year, Bloody Sunday produced 4 or 5 hits the resulted in injuries. One of them was Atlanta's Dunta Robinson decking Phily's DeSean Jackson and both ending up injured. Normally however, only the offensive player gets hurt. But that doesnt mean that the defensive player doesnt get any force from the hit.

Newton's 2nd law states that every force produces an equal and oppisite force. For example, if a defender hits an offensive player with a force of 200 newtons (just an example), the defender feels a force of 200 newtons. Thats the equal part. The oppisite part is refering to the direction of the force, because forve is a vector, so direction matters. So next time Shanwe Marrimen (just kidding), I mean Nick Barnett really lays out a guy, watch and see how fast he gets up. It wont be that fast cause he just got the punishment he just dished out to Tom Brady (thats a funny joke), I mean Chad Henne.

Random Sports Fact: RB Emmitt Smith had the same number of rushing yards in his last season (937) as he did his rookie season.
