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 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.
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.
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.
What example a stop moving force?
An example of a force that can stop an object's motion is friction. When two surfaces come into contact, they experience a frictional force that opposes the object's motion, eventually bringing it to a stop. This force is proportional to the normal force pushing the surfaces together and the coefficient of friction between them.

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!

What is an example of harmful friction and describe how it can be reduced?
An example of harmful friction is when two metal surfaces rub together, causing wear and tear. This can be reduced by using lubricants like oil or grease to create a barrier between the surfaces, reducing the direct contact and minimizing friction.
The friction between the bristles of your toothbrush and the surfaces of your teeth is an example of?
Helpful Friction.
What is the relationship between surface type and the amount of friction?
The magnitude of the force of friction is a function of the normal (perpendicular) force of the object and the surface properties of the two materials. It's a linear relationship; for example, if an object is sliding along a horizontal table with a weight of 2 lbs, then friction will double if an additional 2 lbs of force is added to the object.
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.
Why does Sandpaper have high coefficients of friction.?
It is very rough. But please note that "coefficient of friction" isn't specified for a single substance. Rather, it is specified for the COMBINATION of two different surfaces. It must also be specified if some lubricant is used. For example sandpaper on sandpaper, sandpaper on glass, glass on glass (dry), glass on glass (wet), etc.
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.
