I had contacted Greg Drake Defensive Coordinator/ Recruiting Coordinator and Asked him a few questions about physics in football here is his response
In what ways do forces and friction help a player
-"Force and friction helps a player make tackles on defense by delivering force to a ball carrier. the call carrier can also use force to break a tackle by delivering it to a defender. Force plays a big roll in the trenches of the football field the offense and defensive line as well this is where force and friction is applied the most through blocking"
In what ways do forces and friction make it harder for a player
-" This question pertains to both sides of the ball. The player making the tackle has more force then the offensive player he will make the tackle. If the offensive player has more force he will break the tackle."
Why does friction matter when throwing a football
-" Friction helps in throwing the ball by the qb applying the proper friction and force to throw accurately and for the perfect spiral. The proper friction and force must be applied to the ball to make accurate throws ."
