no friction applies to all contacting stuffs; air, water, glass, buttcracks.
No, friction can be found when two objects of mass touch. Friction can occur between two solid objects, two liquids, and even two gases. It can occur on an global scale, as well as a molecular one. Friction is simply defined as "the resistance that one surface or object encounters when moving over another."

What acts only between surfaces that are in contact?
Friction
What things can increase friction?
If you are running on the carpet there is more friction because it is a rough surface .when you are skating on ice there is less friction because it is a slippery surface. PLEASE GIVE VOTES AND COMMENTS
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.
How does frictional force vary with change in roughness of the surfaces?
More friction is produced on a hard surface than on a smooth surface it takes more force and brute strength to push something heavy on a rough surface, because it falls in the cracks. On a smooth surface you are just sliding across a surface.
Does friction only act on two solid surfaces?
Friction exists in all states of matter, whether solid, liquid, or gas. Of course, there is generally less friction when liquids or gas is involved, than there would be when two solid surfaces are involved.

What are the three properties of drag?
There are four main properties of friction. These include it being an electrostatic force between two surfaces, it acts parallel to the surfaces that are moving against each other, it is independent of the area of the surfaces in contact with one another, and it never initiates motion - it only responds to it.

Is coefficient of friction dependent on the size of the perpendicular force?
No. The coefficient depends only on the two surfaces which are in contact.
What kind of friction is wheels rolling on a car?
kinetic friction, and this motion creates thermal energy from this friction. However the wheels moving on a car is directly created from the work of a combustion engine which creates multiple types of friction, chemical and thermal are the two major types.
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.
