Football is such a brutal sport that incorporates every concept of physics. When someone throws a football they are using physics. Every factor such as the angle, distance, weight, velocity, can tell you different parts of physics. The force of gravity also becomes a factor when a ball travels through the air it travels in a curved motion. The path it takes is called projectile motion. Looking at each player, you can figure out their acceleration they contribute to the team. Each player starts at rest unless they run across because of the play the quarterback chooses. Starting at rest gives you the initial velocity. When the tackle is made and the play is called to a stop you can measure out the distance and the field helps by marking the yards. There is always a play clock. We could use all these givens to help us solve for the acceleration. We could calculate the final velocity using the kinematic equations but a much easier way to calculate the acceleration is by using a formula: a = v/t.
Football has so many givens that help you solve what you are looking for. Imagine a highschool football player weighing at 200 pounds with the acceleration of 3 m/s. Force causes an object to undergo a certain change. The formula for force is: f=ma. We have both the mass and acceleration to solve the force of the highschool student. Anything from the tackle, to punting, to throwing the ball, etc. uses physics.
