Smooth vs. Rough surfaces.
Rough surfaces have more surface area than smooth surfaces. This means that there are increased incidences of molecular reactions between the surface and object

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.
What surface uses the least amount of friction?
wet surfaces like tiles have the least amount oof friction
How can harmful friction be reduced?
Separate the surfaces undergoing friction; this is what hovercrafts and hydrofoils do.Put some lubricating substance between the surfaces undergoing friction; this is the fuction of oils and greases.Coat at least one of the surfaces with a substance that presents less friction; the plastic known as Teflon is sometimes used for this purpose.
What is physical difference between surfaces with high and low coefficients of friction?
A high coefficient of friction may be caused by a rough surface. It may also be the result of surfaces sticking together, as in the case of rubber which tends to stick to certain surfaces, at least when it is dry. Lubrication - such as a thin layer of oil - tends to reduce the coefficient of friction.
Why do smooth and wet surfaces have the least friction?
This is because the surface is more even and equal. For example if you have a wooden surface and a glass surface, the wooden surface would have more friction than the glass, because it is more un-even than the glass surface

What is an experiment that uses a Tech Deck?
Well, you could roll it on different surfaces to see how fast it goes on each surface, and determine which one has the least and most friction.
Is friction increased with inflated tires?
No, when your tire is at the optimum recommended pressure friction is least.- You will notice this most on bicycle tires, when pressure is low, it's harder to pedal. I pump my bicycle tires to 45 psi and have a smooth, fast ride.
What kind of friction does a fish experience when it swims through water?
When you try to hold a fish it reduces the friction a fish experiences by at least 65%. It experiences sliding friction while swimming through water.
Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
What are the advantages of fluid friction?
It keeps you from falling down whenever you try to walk. In general, it keeps things still.
Which surface gives the least friction?
Plane surface with negligible friction.
What is the least frictional force?
That is a poorly phrased question. Friction is a force resulting from molecular interactions between substances. It is numerically calculated using the formula F=μmg, where F is the force from friction, μ is the coefficient of friction, m is the mass of the object friction is affecting, and g is acceleration due to gravity. Thus the least frictional force possible approaches zero as either the coefficient approaches zero (think very smooth surface-like ice) or as the mass approaches zero.
