yes it does but only under extreme and special conditions...
The force of friction does, but the coefficient of friction does not.
The ratio of resistance force to effort force is a mechanical advantage.
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
Yes. Different substances have a different coefficient of friction.
Frictional force depends on the contact force and on the coefficient of friction. The coefficient of friction depends on the types of materials in contact; the contact force may depend on mass, if it is caused by gravity.

No. Coefficient of friction is not measured in units.
quality of the Surface is affected to the Coefficient of friction
No, It does not depends on weight of block because this weight of block is being balanced by normal force. So by increasing weight of block, there is no effect on coefficient of friction.
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.
You need two different materials to determine the coefficient of friction. Without another material you cannot know what the coefficient of friction is.
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.
