Since friction means a contact force, the nature of contact will influence friction force. Smoothness of objects affect the friction force. However, as contact pressure rises, the friction does not rise.

Does the nature of surface in contact influence friction force?
Yes. Roughly speaking, smooth surfaces tend to have less frictional force.
What is the relationship between contact force and friction?
Generally, the higher the contact force, the higher the friction.
The ratio of the resistance force to the effort force is called?
The ratio of resistance force to effort force is a mechanical advantage.
Is friction acontact or non contact force?
It is a contact force.
Does friction depend on the area in contact?
The force of friction does, but the coefficient of friction does not.

Is friction contact or non-contact force?
non contact
What is the force when two materials rub together?
The force when two materials rub together is called friction. Friction is a resistive force that opposes the relative motion or tendency of motion between two surfaces in contact. The magnitude of the frictional force depends on factors such as the nature of the surfaces and the force pressing them together.
Is friction a contact or non conact force?
contact
A curling rock slides to a stop due to the force of friction Is this force of frictiion a contact force or a force at a distance?
The force of friction is a contact force. An example of a force at a distance would be gravity.
What kind of force is an example of friction?
Contact force
Is friction independent of the area of contact?
Generally no. The friction force is typically assumed independent of surface area, and proportional to the force between the two objects. By changing the contact area, you are changing how that force is concentrated. i.e. a small surface area means that your force is distributed across a small region, creating a high pressure (force/area) at the contact. By increasing the surface area, you distrubte that force and lower the pressure. This is, however, an idealization and can break down in some instances.
