It is very small quantity . It varies from one road to another , one vehicle to another , one speed to another also on the basis of amount of air present on the tire , the load in the vehicle etc so we say that friction varies from on situation to another

When a driver wants to stop a car -------------- between the tires and the ----------------------- help stop the car?
When a driver wants to stop a car, they apply the brakes. The friction between the tires and the road surface help stop the car. How a vehicle handles is determined by the traction between the tires and roadway.
How do you tires help save lives in car crashes?
The friction between road and tyre stops the car
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.
What is a type of friction that enables a car to move?
Friction between the tires and the road. Without that kind of friction, we'd never be able to start moving, and wouldn't be able to stop!
Explain why ears skid on curves when the road is icy?
When a car is on a curve, centrifugal force tends to force it outwards. Normally, this force is resisted by the car's tires gripping the road surface. However, ice on the road reduces the friction and therefore the tires cannot grip so well.
What causes road wear?
umm the road, friction between your tires and the roads surface.
What forces created the screeching of tires?
Friction between the tire and the road surface
Why is it more difficult to stop a boat in water than a bus on the road?
Because there is less friction between the hull and the water than there is between the road surface and the tires.
How is the relationship between the friction and surface area of tires unusual?
Throw in variances in road surfaces with friction and tire surface area and the relationship is very unusual... you might call it a 'manage-et-trois'.
Why roads are slippery when yet?
Because there's a layer of water between your tires and the road surface, and it has much less friction than the road surface would. Additionally, oils in the asphalt can be drawn out, contributing to the slipperiness of the road.
When is friction good?
When driving because if there was no friction between the tires and the road, the vehicle would just slide of the road and crash.
What things can affect braking distance?
Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires Things that affect braking distance consist of the following factors: * speed at which you're travelling * weight of the car * road conditions * braking efficiency * friction between the road surface and your tires
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.
Why do tires screech when the brakes of a car are slammed on?
The friction between the road and the tires creates and screeching sound.
When a driver wants to stop a car -------------- between the tires and the ----------------------- help stop the car?
When a driver wants to stop a car, they apply the brakes. The friction between the tires and the road surface help stop the car. How a vehicle handles is determined by the traction between the tires and roadway.
Why the tires of a car get hot when the car is driven?
The simple answer is friction. Spinning tires are coming into contact with the road. The road's surface is not perfectly smooth -- it has a certain amount of roughness so the tires can grip and propel the car forward. Any time you have friction between two surfaces, and one of those surfaces moves to overcome that friction, a certain amount of energy from the process is lost as heat.
If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
