Does a pulley use friction?
no
Why is friction a nuiscance in a pulley?
It wastes energy. However, SOME friction is also needed, or the pulley would just slip.
What type of friction does a pulley overcome?
sliding
Does static friction or rolling friction causes a car tire to turn on the road?
static friction
What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
When a car's tire are stuck in the snow or mud is it better to have more or less 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.

Does tire friction increase gas milege?
All types of friction increase fuel consumption. Wind resistance. Tire resistance. (The bigger the tire, the bigger the contact patch, the more resistance.) Engine parts, etc.
Which wheel of vehicle will have more friction one having wider tire and one having sleek tire?
Friction or grip if it's friction i think the tyre with the most contact with the road surface. If it's grip then the one with the tread
Why is a tire rolling on the ground rolling friction?
Friction is the resistance to sliding and as a tire rolls it does resist friction, otherwise it would slide.
What type of friction does a pulley overcome?
sliding
What is prusik minding pulley?
friction hitch
How is friction good?
Friction is good for two reasons, both are related. 1) Friction allows your car to stay on the road. Bigger tire surface translates to more friction=better handling. Also 2) friction stops your car (brakes). The bigger the contact surface from the tire (the tire touching the road) and the better the braking system (drum brakes or disk brakes), the quicker your car will stop.
Rosa has designed a pulley system for a school science project She has determined that as the coefficient of friction increases the efficiency of the pulley decreases With a coefficient of friction?

How does tire tread increase friction between tire and road?
tires are made of rubber and rubber can cause friction
What creates the forces that causes a wheel and tire to bounce?
It is called friction Out of balance. More weight on one part of the tire than another.
