Re: [Phys-l] Work done by Static Friction



No time to look this up (64 papers to grade), but I seem to recall that one can preserve the Work/Energy theorem in this case if one looks at what is happening microscopically? Maybe akin to the fact that any horizontal surface must deform slightly to hold up a mass placed on that surface? Just wondering.

Some physicists proposed that 'static friction' to be
named "shear adhesion" instead. You may consider transfer of "Coulomb energy" from the microscopic view?
