It sure would be nice to have ways of finding the locations of minima efficiently… • Between any two minima (valley bottoms) the lowest energy path will pass through a maximum at a saddle point. In chemistry, we call that saddle point a transition-state structure. They’d be nice to find too…

      POTENTIAL ENERGY Potential energy is a measure of the amount of work a conservative force will do when it changes position. In general, for any conservative force system, we can define the potential function (V) as a function of position. The work done by conservative forces as the particle moves equals the

      The Potential energy (PE) of a structural system is defined as the sum of the strain energy (SE) and the work potential (WP). PE =SE +WP (1) The strain energy is the elastic energy stored in deformed structure. It is computed by integrating the strain energy density (i.e., strain energy per unit volume) over the entire volume of the structure ...

Potential energy also appears in several forms. Gravitational energy comes from the potential power gravity can have on the object.
