There isn't one, it's a myth! God created everything in his image. God is frictionless and therefore so are we
quality of the Surface is affected to the Coefficient of friction
You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
With what material? Coefficient of friction is for two materials.
The coefficient of friction is the same in this case.
The force of friction does, but the coefficient of friction does not.
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).

No. Coefficient of friction is not measured in units.
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.

The coefficient of friction is dimensionless; it has no units.
With what material? Coefficient of friction is for two materials.
The coefficient of friction is a scalar quantity which has no direction which does not have an angle.
A higher coefficient of friction indicates that two surfaces in contact have a greater resistence. A lower coefficient of friction indicates that the two surfaces in contact have less resistence. Soccer cleats on grass have a greater coefficient of friction than skates on ice.
