The effects of friction can be found in several areas of football (I assume you're speaking of the American brand of Football, not the European/Southern Hemisphere brand). 1) When the quarterback throws a pass, there's friction between his fingertips and the ball, helping to impart spin to the football in the air. 2) Runners need a good grip between their shoes and the surface of the playing field, and other than gravity, friction provides the good footing they need. 3) There is a small amount of friction between opposing players during blocking and such. Attempts to diminish the friction by liberally applying, say, vaseline, to your jersey would be viewed with disfavor by the local officials. .
what is the effect of friction force on plant
If there is more friction with a machine, efficiency is less.
more friction = less speed
yes
less friction
first you ejaculate onto the football, rub it around in your hands a bit and slide it across a smooth floor and WA LA you have sliding friction on a football XD

Friction is essential for Walking and other movement. So obviously it is of paramount importance in football. Without friction, A player can't grip the ball, the ground pr other players. Running, which is the base of football, doesnt exist without friction. Hence, no friction = no football.
it rubs the steel because its friction!
No
No effect

first they are called cleats not boots and they dont have friction.
yes
less friction
Friction inhibits the motion of objects.
