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.

How do mass and surface type affect friction?
if the mass is more than the friction is high. and if the surface is rough then also the friction is more. thus we can say that both mass and surface type affects friction.
Is friction high or low a car tire on a road surface?
high
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.
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 are examples of low friction materials?
Some examples of relatively high friction surfaces are: sand paper, grass, and asphalt. In general, the rougher the surface, the more friction it has.
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..
What surface has the least amount of friction?
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Do different surfaces affect the bounce of a bsketball?
Yes. If the surface is soft the basketball will not bounce as high, but if the surface is like a gym floor the basketball will bounce extrememly well. Also you have into consideration the force of friction. The more friction the surface can produce the slower the ball will go.
When climbing where do you need high friction?
You need high friction on your climbing shoes when making contact with the rock surface, especially on small holds or slippery surfaces. High friction helps you to maintain grip and stability while ascending the rock face.

Why do jet streams have such a high velocity?
Because of the high altitude, these winds are not subject to much friction, hence they are faster than winds closer to earth's surface.
