Does friction act on a table resting on the floor?

yes,it does act on the table because both the table legs and floor have irregularities due to which they get attached to each other and that is why we have to apply force on table to move it

sorry i repied in hurry and didn't thought the question through
the right answer is no
since no force is applied on the table then frictional force will not act on the table

Answer:
Explanation:
Friction acts on objects at rest too . The definition meant that if there is relative motion between two objects then friction will act as a resistance between them . If you find two objects at rest even when an external force is applied on it then it means friction is acting on them . Had there been no friction there would have been relative motion and the definition means that this motion will be opposed by friction ( if it happens to exist ) .
In the static case, the frictional force is exactly what it must be in order to prevent motion between the surfaces; it balances the net force tending to cause such motion.
