Is the force in coefficient of friction experiment only due to the surface of contact between block and board?

Yes - even though there is an extremely small amount due to the block and air. In the experiment that is usually not taken into account even though strictly speaking it should be

What happened to the coefficients of friction as the surface area of the contact increased?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.
What are the two factors that affect the friction force between two surfaces?
The strength of the force of friction depends on the types of surfaces involved and on how hard the surfaces push together.
What is coefficient of friction..?
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.
What is friction coefficient?
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.
How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- 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.
The coefficient of friction is a blank number that represents the resistance to sliding between two blank in contact with one another?
Unitless, surfaces
Why sliding friction greater than rolling friction and if the area of contact is same?
The FORCE of Friction is INDEPENDENT of Surface Area. Only the 'Coefficient of Friction', and the Force between the two Surfaces. Sliding Friction is greater than Rolling Friction ONLY if the Coefficient of Friction is GREATER for the Sliding Surfaces.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
The is a number that represents the resistance to sliding between two surfaces in contact with one another?
The friction is a number that represents the resistance to sliding between two surfaces in contact with one another. It is measured in Newtons (N).
Will frictional force depends on mass and density?
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.
