comment What is it called when a fluid will “jump” to grab onto an object that comes very close?
Adhesion? There's probably a more technical term for it, that's just what I know from basic chem.

comment When is the principle of virtual work valid?
I appreciate the response. I understand your answer regarding how sliding frictional forces are not 'unduly hampering'. But I still don't see why the principle of virtual work is not true when sliding friction forces are present? To me, I am thinking that if the friction force is not a constraint force, then the principle of virtual work should say nothing about it.
