  1. Physics of football Steven Barron

  2. 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 “prolatespheroid" - the football - can throw kinks into a game no physicist, player or fan ever saw coming

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

  4. Mass • Players weight ,  A player's center of mass - the point where gravity acts on an object

  5. velocity • From 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.

  6. acceleration • Better shoes for maximum traction. Lose weight and/or gain leg strength for acceleration.

  7. torque • When a player crouches down, keeping low, his center of mass is closer to the ground. Therefore, the potential torque is small.
