Examples of high friction?
Example of high friction is a really rough surface like sandpaper.
How does sandpaper slow thing down?
All materials have a property called the coeffecient of kinetic friction. When this property is high, a higher friction force resists the motion of objects across the surface. Sandpaper has a higher coefficient of kinetic friction as compared to something like ice. This is because ice is smooth whereas the surface of sandpaper is very rough which increases the friction it causes.
How does lubricating machinery-such as the chain on your bike reduce friction?
The surface tension between the metal on your chain pieces is high. The surface tension is low on lubricants like oil or graphite so putting them between moving surfaces provides a opposing surface for both materials that has a low friction.
What materials can prevent friction and which one can increase it?
high friction materials can prevent sliding under high loads or steeps incline.insome situations,adding a libricant actually increases the friction, due to molecular effect.
Do rubber tyres show more friction or less friction?
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.

Is friction high or low a car tire on a road surface?
high
Why does rubber generate so much friction?
Rubber induces high friction because of its high coefficient of friction. The surface of rubber is rough and elastic, allowing it to deform and grip the surface it comes in contact with, resulting in increased friction. Additionally, the intermolecular forces between the rubber and the other surface further enhance the friction generated.
What are examples of high friction surfaces?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
If you go sking do you need high or low friction explain?
When skiing, you need low friction to glide smoothly over the snow. High friction would cause you to feel resistance and make it difficult to slide across the surface. A low friction surface allows you to maintain control and move efficiently.
Is a car tyre in contact with a road surface high or low friction?
A car tire in contact with a road surface provides high friction. This friction is necessary to ensure proper traction between the tire and the road, allowing the vehicle to accelerate, decelerate, and navigate turns safely.
Does wood have high friction?
Yes, wood typically has a high coefficient of friction due to its rough surface texture and ability to generate significant resistance when in contact with other surfaces. However, the friction can vary based on factors like the type of wood, its moisture content, and the smoothness of its surface.
How do mass and surface type affect friction?
Mass affects friction by increasing the normal force between the surfaces, which in turn increases the frictional force. Surface type affects friction by altering the coefficient of friction between the surfaces - rougher surfaces typically have higher coefficients of friction which results in greater frictional forces.
What are the factors which affect the coefficient of static friction?
Dry surfacesFor low surface pressures the friction is directly proportional to the pressure between the surfaces. As the pressure rises the friction factor rises slightly. At very high pressure the friction factor then quickly increases to seizingFor low surface pressures the coefficient of friction is independent of surface area.At low velocities the friction is independent of the relative surface velocity. At higher velocities the coefficent of friction decreases.Well lubricated surfacesThe friction resistance is almost independent of the specific pressure between the surfaces.At low pressures the friction varies directly as the relative surface speedAt high pressures the friction is high at low velocities falling as the velocity increases to a minimum at about 0,6m/s. The friction then rises in proportion the velocity 2.The friction is not so dependent of the surface materialsThe friction is related to the temperature which affects the viscosity of the lubricant
What material produces the most friction in a rough and dry surface?
While there is no definite answer, the substance that produces the most friction when rubbing up against another substance is almost certainly rubber. This is why it is used in tires.
When someone is clombing when do they need high friction?
When climbing, high friction is needed when the holds are small or difficult to grip. By generating more friction between your hands or feet and the surface of the holds, you can improve your grip strength and stability, making it easier to climb. Additionally, high friction can help prevent slipping and falling while climbing.
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..
