Super Bowl Sunday



I KNEW THE SAINTS WOULD WIN! Ahhh I knew I shouldve bet some people for lunch because everyone thought that the colts would win. Anyway, I never wrote a blog about physics concepts in football yet so i will now. First, there's the obvious concept of projectile motion. The quarterback releases the ball with some initial velocity and it travels to the receiver as the football is under the effect of gravity. Another concept is momentum. When a linebacker comes and sacks a quarterback, momentum is conserved before and after the collision. However, this is an inelastic collision since the linebacker and the quarterback together with the same velocity. Finally, if there was some wind in the stadium, there could have been hints of air resistance, a non-conservative force going against the direction that the football is traveling. All right, hope everyones had a good weekend.
