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.
ill say air friction because of the ball
Ice skating is because you dont go fast and there is rarely any friction
An Ice skater skating on ice.
ice skating on ice ,is one friction occurring
In engines - during ice skating.
Ice skating uses friction to make you move smoothly across the ice rink.Friction is in just about all movements.
Ice skating does not require any friction because the skater needs to glide on the ice and if there was any friction on ice the skater would have trouble to skate smoothly on the ice. That is why ice skating does not require any friction at all from my perspective.
for slowing down, stopping etc
Let us go for an answer that you may not have thought of shall we? If you were skating on ice and you built up speed then stopped skating, eventually you would stop. Why? because ice has friction though very little. This friction works on the friction on the blades of your skates bringing you to a stop.
If you were roller-skating you don't need friction because it slows you down. Well you want friction between the wheels and the floor (so you do not slip sideways) but not between the wheel and the axel (thats why you have ball bearings there to reduce rolling friction). If you are ice skating you do not want friction between the blade of your skates and the ice.
Because friction is a force acting against the forward motion of the puck, friction is going to play a role in slowing down the puck as it glides across the ice. The friction is not going to be great enough to stop it instantly, but if not touched by another stick for some time it will come to a stop.
Friction is basically everywhere, but if there is a object in front of that it will automatically slow you down. Ex.when you are on an ice skating rink nothing can stop you because there is no friction at all. But when you are on a football field the object (grass) is in front of the friction it would slow you down more than it would when you are on an ice skating rink.
