Answer:
The friction force is basically due to the irregularities of surfaces. If a surface is rubbed to make it smoother, then the force of the friction provided by that surface will reduce. A perfectly smooth surface offers negligible friction.

Answer:
Rough surfaces have greater friction than smooth surfaces. Rough surfaces have grooves on them. When two rough surfaces are in contact, the grooves of one go inside the grooves of the other, thus making the movement difficult. Hence, roughness increases friction
