Physics of footballSteven Barron

FOOTBALL!!!!Football is a sport almost made for physicists.

Newton's 3 laws of motion are at work during every play and little things like the unpredictable bounce of the “prolate spheroid" - the football - can throw kinks into a game no physicist, player or fan ever saw coming

The action that happens on a football field involves mass, velocity, acceleration, torque, and many other concepts...

MassPlayers weight ,  A player's center of mass -

the point where gravity acts on an object

velocityFrom big and bulldozing, to small and speedy,

NFL running backs come in many shapes and sizes. But to succeed at football, all running backs must excel at kinematics, the branch of classical mechanics that defines how objects move.

accelerationBetter shoes for maximum traction. Lose

weight and/or gain leg strength for acceleration.

torqueWhen a player crouches down, keeping low,

his center of mass is closer to the ground. Therefore, the potential torque is small.
