Football Physics

I have found that physics is prevalent in football in many different ways, from the projectile motion of the throws and kicks to the forces of momentum in the tackles. When the quarterback throws the ball, if follows an arch where the ball is going up, comes to a stop in the vertical direction, and then starts coming back down, and hopefully falls into the hands of another player. For this to happen the quarterback must take into account the angle at which he releases the football because the higher he releases, the higher the ball will go but not as far, and to throw the maximum distance he should throw about 45 degrees. Also, he must throw with a certain initial velocity to get the ball to a certain place faster or slower, and to get it the proper distance. Also, the momentum of football is something that we can easily consider. When on football player tackles another, they generally stay together, making this an inelastic collision. For the momentum to be conserved, the mass and velocity of the first football player must be the same as the second, or else the tackle will be broken, or the tackler will knock the ball carrier back.
