Question

Explain how friction can be increased in between two surfaces placed in contact with each other


Plz help me​

Answer 1

Explanation:

Frictional force always acts parallel to two planes in contact with each other and in a direction opposite to that of relative motion of the two bodies. ... Frictional force always decreases the relative motion between two bodies or surface. 4. Frictional force is more for rough surface and less for smooth surfaces.

Hope it helps you
