Force Of Friction


We can find he effect of friction during a football throw with the quarterbacks figertips and the football. Friction helps the quarterback hold on to the ball and be ready to throw ball.The football has special laces to help the quarterback girp the ball. Once the quarterback throws the football, the friction between quarterbacks figertips and the football help spins the football which makes a spiral. Force of friction can be find when someone is trying to catch the football as well. Friction helps the catcher catch the ball and stop the football from accelerating anymore.

Force of Friction

Denver Broncos Quarterback Peyton Manning
Therefore the force of normal is 3.9N
Force Of Normal
We found the coefficient of friction between skin and leather, so we can then calculate the force of friction on the football, but first we have to find the normal force using the Fnet equation.
Therefore the force of kinetic friction is 2.4N
Therefore the force of static friction is 2.8N
