What is rolling friction and sliding friction?
I assume this relates to a wheel. When the wheel is rolling, the surface of the wheel is not moving relative to the surface of the road when they are in contact. however, the wheel deforms slightly and because of this, the normal force slightly opposing the motion of the wheel rather than simply pushing it up. This is rolling friction or more commonly known as static friction. When the wheel is sliding, the wheel is sliding over the road's surface, meaning that there is relative movement between the wheel and the road. this is known as sliding friction or kinetic friction.
Does surface type affect the force of friction?
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
How does friction effect a car in motion?
Friction can have many effects on a moving car. It depends on the situation under discussion. If the tyres are brand new, more friction will be experienced as the grooves of the tyres will interlock with the surface of the road. But when the tyres are wearing away, their surface becomes relatively smooth. Friction will not have as great an effect. If the road is layered with snow, friction will be minimal and the car will move with great velocity . . . uncontrollably. This is why a car skids on an icy road. Where friction prevents a fast driver to reveal his real potential on the highway, it also helps him apply brakes. It is friction which assists the tyres to stop moving .
Is the friction between car tires and pavement greater when the car is at rest or in motion?
Interesting - static friction is greater than moving friction; but if the car is not in a skid, then the part of the tires in contact with the road is not moving ... thus static friction holds in both cases.
How does friction act on a car?
According to wikipedia friction is defined as: "the force resisting the relative motion of two surfaces in contact or a surface in contact with a fluid (e.g. air)." Thus there are would be 2 locations friction would occur on a moving vehicle: (1) air resisting the motion of the vehicle; (2) friction between the tire and the ground. Two types of friction can occur between the tire and the ground, a) static friction, and b) kinetic friction. Static friction is when the tire maintains grip or traction on the road surface, whereas kinetic friction (as the name implies) is when the tire is moving relative to the ground. To illustrate static friction, consider for a moment a dot on the tire's surface. Your vehicle is moving forward (let's say it's moving very slowly), and your tire rotates so that the dot comes into contact with the ground at a certain point. Since a car tire compresses a bit on the road's surface, there's approximately 3-4 inches of tire flat against the road at any given time. As your car moves forward, the tire rotates, and once the dot touches the ground at a given point, the tire and the ground move at the same rate relative to the car. That is, the dot on the tire and the point on the ground remain in contact until the tire reaches the end of that 3-4" strip of contact, when it is pulled upward from the ground to rotate around top and back to the ground. An example of kinetic friction from the illustration above would be that the dot on the tire reaches a point on the ground, but the dot and point move away from one another. In real life this would be if you hit the brakes and skid, or if you hit the gas and burn out or spin your tires (e.g. in the snow or mud). The problem with kinetic friction is that it is weaker than static friction. Thus, when you hit the brakes, if your tires lock up (you'll hear the squealing tires against the road) you are now in kinetic friction and your car will slow down less (actually speed up) compared to when your tires were in static friction with the ground. That is why you pump your brakes... also why anti-lock braking systems (ABS) were developed.
Is friction high or low a car tire on a road surface?
high

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.
Where is friction in cycling?
the friction is between the tyres of cycle and the road surface. Without friction movement is impossible.
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
What causes road wear?
umm the road, friction between your tires and the roads surface.
How does friction affect bicycling?
Well.. There is surface friction from the tires on the road, there is air friction from the bike itself ,, more air surface friction if your on it.. Then there is mechanical friction through the resistance of the, chain, bearing assembly grease in axle.
Cars skid more easily on rainy days?
There is less contact between the tyres of the cars and the road surface on rainy days. The rainwater filling up the grooves of the tyres and the rainwater on the surface of the road prevent the tyres from gripping more tightly to the road surface. In other words, water reduces the friction between the tyres and the road surface.(This is the exact answer! Did a lot of research to come up with this answer!)
Why do friction is high in very smooth surfsces?
i honestly didnt get ur ans but ill still try to help u out.. friction is the opposing force to a motion, when the surface is very smooth friction reduces.. i.e the smoother the surface the less the friction.. for eg.. if u spill oil on the road the car starts slipping and becomes hard to stop it i.e bcos the surface becms smoother and reduces friction..

Example of sliding friction?
Any object moving at a certain speed relative to the surface with which it is in contact. (A car moving on a road)
What forces created the screeching of tires?
Friction between the tire and the road surface
