Question

Frictional force depends an das ​

Answer 1

Explanation:

The amount of friction generated depends on numerous factors, including the minute intermolecular forces acting between the two surfaces in contact – so-called van der Waals forces. ... They have discovered that frictional force is affected by the composition of the materials beneath the surface.

Answer 2

It depends on the surface.

For example, if anyone is moving on a rough surface we will find that is difficult to move and while we are walking on a floor which is slippery we'll find it that we are not able to move in the way we move on a road.

Here the simple logic is that friction force is a contact force and while moving in a rough surface it gets interlocked.
