Frictionless surface?

  1. Oct 10, 2004 #1
    Is there anything such as a frictionless surface? Why?

    No. Because friction (both static and kinetic) is caused by instantaneous electric attractions between the particles of two surfaces. Only a vacuum could be frictionless, but of course then there is no surface.
