The friction is the inter molecular force between any two surfaces of contact. Though the surface of glass looks smooth, but the intermolecular force with the other surface in contact with glass has certain amount of experiencing to friction in locking through bond between the molecules. Here the coefficient friction is a constant given by the equation. It has no units. The coefficient of static friction is greater than the kinetic friction on the same surface.
