... If Fdr is independent of path (and this will be true if F = 0), then we can define a potential energy: V(r) = - rsr Fdr (where rs is some standard position). If all the forces in the problem can be put in terms of potential energies, then we can use the Conservation of Energy to relate the vel ...
