Scaling laws in the macro-, micro- and nanoworlds
... However, below say L = 1 mm, Fgr is much less than Fvdw . Gravitation may then be neglected at such small dimensions, both in the micro- and the nanoworlds. When two surfaces are sliding about each other, at the macroscopic level, the friction force is given by Ff r = µFgr = µmg, where µ is the fric ...
