when cricket players make the ball swing 1 side is shined if the left side is shined then it swings in to the right handed bats and the rough hits the floor more friction makes the ball swing as the rough side will grip the pitch therefore keeping the seam straight

The role of friction in soccer is the same as the role of friction in any other sport with a ball. Friction between the ball and grass or artificial turf slows the ball, sometimes considerably. Both offensive and defensive players can use that to their advantage...an offensive player may kick the ball down the field knowing the grass will stop it before it gets to the end line and goes out of bounds, while a defensive player may attempt to the shield the offensive player from getting to the ball so that it *does* go out.
There are two important factors when it comes to the field and friction, 1) whether it's grass or artificial turf (which directly translates to "how long is the grass"), and 2) if it's wet or dry.
1) grass v artificial turf: most times turf is much shorter than grass, so the ball "runs" (doesn't stop rolling) when playing on turf. Players need to take care to not kick the ball too hard or it may go out of bounds before he (or the receiver) can get to it. Also, the longer the grass, the slower the ball will roll and the quicker it will stop. As stated above, an astute player will test the speed of the pitch in pre-game warmups and figure out how hard he can kick it and use that to his advantage during the game.
2) wet v dry: there's a dichotomy here.... a ball will generally roll further on dry grass than it will on wet grass of the same length, *BUT* an airborne ball will "skip" on wet grass.
Get this...if the ground is dry and a ball is kicked so it's rolling it will go X distance (rolling). If the same ground becomes wet and the ball is kicked with the same power it will go *less* than X distance (rolling).
The dichotomy is in that same scenario, the reverse may be true if the ball leaves the ground. If the ball leaves the ground it will mostly likely "skip" on wet grass/turf and go further than if the ground was dry.
The friction between the shoes of the player and the court.
The fluid friction between the shuttlecock (bird or birdie) and air present in the atmosphere will help us to play the game.
As the force applied will be equal to the force effected, the body is controlled by the friction and also pushed forward by this friction. It also works by the pressure of our cells.
