The breaks on your car require friction to make the car stop. Friction between the souls of your shoes and the ground keeps you from sliding.
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
Racing because friction slows you down but you need to go fast.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
A piece of sand paper on a piece of wood is an prime example of rubbing friction.
An example of unuseful friction is when trying to push a heavy object on a rough surface where the friction makes it difficult to move the object smoothly.

Automobile brakes and clutches require friction. We also need friction between the tyres and the road when we accelerate or when we brake or when we turn a corner.
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
An example of fluid friction is the air resistance felt by an airplane.

Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
A piece of sand paper on a piece of wood is an prime example of rubbing friction.
Ice skating is because you dont go fast and there is rarely any friction
An example of unuseful friction is when trying to push a heavy object on a rough surface where the friction makes it difficult to move the object smoothly.
Some machines need friction to operate. Brakes, grinders, traction wheels, and others all rely on friction to work. In other cases, friction is bad. electric and fuel-fired powerplants for example, are all designed so as to minimize friction. That's why the lubricant industry exists!
