Which two surfaces would have the highest cofficient of friction?
Two rough surfaces with high friction coefficients would have the highest coefficient of friction. For example, rubber on concrete or sandpaper on wood would typically result in a high coefficient of friction due to the roughness of the surfaces.
What is an Example of low coefficient of friction?
One example of a material with a low coefficient of friction is polytetrafluoroethylene (PTFE), commonly known by the brand name Teflon. PTFE is a synthetic fluoropolymer that exhibits excellent non-stick properties and is widely used in applications where reduced friction is desirable, such as in cookware and as a lubricant.
What is the value of coefficient of friction of emery cloth?
Depends on the other surface. Coefficients of friction are generally tabulated for pairs of materials. Emery cloth on Teflon, for example, will have a lower coefficient of friction than emery cloth on rubber.
What is the coefficient of friction for marble?
The coefficient of friction is not defined for a single substance, but for two substances that have contact with each other - for example, marble with marble, marble with wood, etc.; it may also vary a lot depending on lubrication. That is, on a wet wet marble floor you'll slip easier - there is less friction - than on a dry one.
Give an example of two surfaces that would have a low coefficient of friction?
Friction is the static electricity of two things that are rubbed against each other. Ice would have a low coefficient of friction, as things could easily slide across it. This would also make sense for something like marble, which is very smooth.
An example of two surfaces that have a low coefficient of friction?
human joints are an excellent example. they have a static friction coefficient of .01 μs and a kinectic friction coefficient of .003 μkanother good example would be waxed wood on dry snow (as in a snowboard on a ski slope) this has a static friction coefficient of .04 μsHope this helped!

Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).

What does the coefficient of kinetic friction depend on?
The coefficient of friction is a scalar value with no dimension. It is simply a ratio of the force of friction between two objects, to the force pressing those objects together (often the normal force). Slippery surfaces have lower coefficient of friction than rough surfaces.
Why the coefficient of friction cannot be zero?
The coefficient of friction is an empirical measurement and has to be measured experimentally, and cannot be found through calculations. Rougher surfaces tend to have higher effective values. Most dry materials in combination have friction coefficient values between 0.3 and 0.6. Values outside this range are rarer, but Teflon, for example, can have a coefficient as low as 0.04. Therefore, a value of zero would mean no friction at all, an ELUSIVE property even magnetic levitation vehicles have drag.

Example of low co efficient of friction?
Ice on ice has a low coefficient of friction, making it easier for objects to slide across its surface with minimal resistance.
