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.
Do smooth surface produce friction?
Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.
Does friction only occur on earth?
Friction occurs between two surfaces in contact with each other. While friction is commonly experienced on Earth due to the presence of solid surfaces, it can also occur in other environments, such as in space where interactions between objects can create friction.
Does friction occurs only between solids?
No, friction can occur between any two surfaces in contact, regardless of whether they are both solids. Friction can also occur between a solid and a liquid, a liquid and a liquid, or a solid and a gas.
What is a way to reduce friction between 2 surfaces?
Increase the total area of direct contact between the two materials and decrease minute deviations from direct contact of the materials, also use a superconductor as a "mortar." Additionally ensure the two materials are of different conductivity. Additional mass may be used to add to the gravitational force pressing down on the surfaces once they make contact. Additional friction can be achieved by the use of force on the lower surface only, allowing the upper surface to remain static. or 1. Roughen the contact surfaces (increasing the surfaces areas), 2. Dry the contact surfaces, 3. Use softer materials, 4. Eliminate all loose materials between the contact surfaces, 5. Increase the weight of the moving body, 6. Apply a sticky substance to contact surfaces, 7. Remove all lubricating substances from the contact surfaces. 8. Adding Weight to object (sand boxes in cars for icy roads)
What is acts only between surfaces that are in contact?
Friction
Which is the only adhesive you apply to both surfaces?
You should apply contact cement to both surfaces.

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.
Work done by static friction is alway?
In the reference frame of the interface between two surfaces, static friction does Zero work, because there is never displacement between the surfaces. But it can be positive , negetive or zero with respect to choosen frame of reference.
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.
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.
