Question

what happens to the force of friction if the surface of contact is polished?

Answer 1

When the two surfaces in contact are made extremely smooth. They come in intimate contact with each other. So force of adhesion comes into play. Due to this force, the motion of one surface over the another surface becomes retarding and hence causes an increase in the friction

Answer 2

Answer:

When two surfaces in contact are polished beyond a certain limit and made extremely smooth, they come in intimate contact with each other. Now, the force of adhesion comes into play. Due to this force, the motion of one surface over another surface becomes retarding and hence causes an increase in the friction.
