Question

is friction force between 2 very smooth surfaces zero ?​

Answer 1

Answer:When two smooth surfaces are in contact, then the degree of friction between them is small because the interlocking between smooth surfaces is less but can't be zero because friction exists at even atomic levels too.

It can't be 0.

Explanation:

Friction‘ is a force that resists motion of sliding or rolling of one object moving relative to another. It is a result of the electromagnetic attraction between the charged particles of two touching surfaces. We find and use it everywhere and every day whenever objects come into contact with each other. Although it always acts in the always acts in the direction opposite to the way an object wants to slide.
