There is not a sport in which friction is not useful. In hockey, for example, there seems to be no need for friction. However, in order to get moving or stand at all, the players rely of the friction between their skates and the ice. The friction between their skates and the ice also creates a thin layer of water while they skate, allowing them to glide over the ice. even chess relies on friction so the pieces do not move off the board.
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).

Friction is a force that opposes motion. Maximum friction is the?æ force that must be overcome in order for a body to start moving.?æ Maximum friction is equal to the?æ product of normal force and coefficient of the friction.
More friction, you need friction in order to get out. Place something in front or behind the tire in order to get out, even a cloth towel will help.

going by something that is moving in order to get in front of it
friction is when two objects or air rubs together and creates heat which the slows the two objects down. its like carpet burn your trousers rub against the carpet it slows you down and hurts!
Sliding friction is the friction between the body and the surface on which the body is sliding. Static friction however, is the friction when the body isn't moving when you aply force to it. The force of static friction is the same as the force you are pushing the body UNTIL it moves!..It's a fact that the static friction coefficient is a bit bigger than the sliding friction coefficient.
oil does not make your car move, it reduces friction in the moving parts in order to keep your car from tearing itself apart
Frictional force resists movement. In order to set an object into motion (or accelerate an already moving object), the force of friction must be overcome.
