College Physics: Do All Potential Correspond to Conservatism?
The fact that the work done by the conservative force has nothing to do with the path, in other words, the divergence of the conservative force is all zero, it can be concluded that the conservative force can be expressed as a gradient of a vector, and the only vector is the potential energy of this conservative force.

In other words, because the potential energy is related to the position, if it is a non-conservative force, the work done from A to B will change with different paths, so if the potential energy at point A is known, the potential energy at point B still has different answers. (In fact, a non-conservative force can also be expressed as the curl of a vector, so that non-unique vector is often regarded as the potential energy of that non-conservative force, such as magnetic potential. )
