... We have seen that the potential energy U(r) corresponding to a force F(r) can be expressed as an integral of F(r). It should come as no surprise, then, that we can write F(r) as some kind of derivative of U(r), although we have to preserve the effect of the dot product in the integral, which turns t ...
