>>11051128>Amontons' Second Law: The force of friction is independent of the apparent area of contact.But this is only an approximate law. So the question is, in what direction does it deviate? It seems perfectly possible to me that there are interfaces that violate the friction equation in both directions:
1) as surface area increases, the area of surface interaction increases
2) as surface area decreases, pressure increases, and so does the interaction per unit area of the two surfaces
But it also seems reasonable that in the case of a rigid, chemically inert surface, 1) would dominate
