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 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.
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.
Substances used to reduce friction?
Lubricants are used to reduce friction, as well as grinding the surfaces in contact until they are very smooth.
What is the coefficient of friction between a perfectly smooth body and a very rough body?
The coefficient of friction depends on the type of materials. Different pairs of materials have different cofficients of friction.
Why is tough to write on a very smooth paper?
It has to do with friction. The smooth paper allows the pen or pencil to slide while rougher paper doesn't.
What surface doesn't cause a lot of friction?
A very smooth surface or a smooth surface coated with a liquid, oil or a Teflon like substance.
Why do lithospheric plates move very slowly?
Very high friction.
What does smooth surface mean in friction?
It then presume the friction is very small and presume no friction. In fluid and piping, it mean any pressure drop term is due to fluid motion and dispersion alone.
What are two examples of two surfaces that have a low coefficient of friction?
Ice and glass both have very low coefficients of friction because they are very smooth, so it is easier for a substance to glide over them.
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.
Is sliding got high or low friction?
Low friction is made when you rub smooth surfaces together, and they slide easily. For example, a melting ice cube would easily slide across a glass table because there is low friction. In contrast, high friction is when there is high resisting force. For example, if you rub velcro across a rug, there would be high friction, and it would be more difficult than sliding the ice across the glass table.
When is decreased friction helpful?
Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
