Question

When the two surface in contact are smooth the friction between then will be small?why?give reason?

Answer 1

Answer:

The friction will be small due to reduced surface irregularities.

Explanation:

Friction is an opposing force that resists the relative motion of the surfaces in contact with each other. This opposing force is developed due to the surface irregularities. Increased irregularities indicate that the frictional force is higher. For smooth surfaces, irregularities will be much lesser. This is the reason why smooth surfaces have a less frictional force acting on them.
