Physics of Sport - Football

Force of Friction applies to football in 3 different ways. Static Friction will apply when the ball is lying on the ground, and the Static Friction will prevent the football from moving, although a very small amount of force is needed to move the football. Kinetic Friction will apply when a player is moving on the field, and the field creates a force that acts against the moving player, or when the football is rolling on the field, friction from the field will resist the football from movement. Applied Force is the force that players act on the football by throwing it, as well as on each other when they tackle or bump into each other. It is what makes the ball move and allows for passing, hitting and kicking.
