The minimum total potential energy principle is a fundamental concept used in physics and engineering.It dictates that at low temperatures a structure or body shall deform or displace to a position that (locally) minimizes the total potential energy, with the lost potential energy being converted into kinetic energy (specifically heat).
The principle of minimum energy is essentially a restatement of the second law of thermodynamics. It states that for a closed system, with constant external parameters and entropy, the internal energy will decrease and approach a minimum value at equilibrium. External parameters generally means the volume, but may include other parameters which ...

In particular: (see principle of minimum energy for a derivation) [8] When the entropy S and "external parameters" (e.g. volume) of a closed system are held constant, the internal energy U decreases and reaches a minimum value at equilibrium. This follows from the first and second laws of thermodynamics and is called the principle of minimum ...
For many systems, L = T − V, where T and V are the kinetic and potential energy of the system, respectively. [3] The stationary action principle requires that the action functional of the system derived from L must remain at a stationary point (a maximum, minimum, or saddle) throughout the time evolution of the system. This constraint allows ...
In the early morning hours of Dec. 26, 1996, Patsy Ramsey called 911 to report her 6-year-old daughter JonBenét missing, and found a rambling ransom note left inside their Boulder, Colorado, home.
Therefore, the abbreviated action can be written = = since the kinetic energy = equals the (constant) total energy minus the potential energy (). In particular, if the potential energy is a constant, then Jacobi's principle reduces to minimizing the path length s = ∫ d s {\textstyle s=\int ds} in the space of the generalized coordinates ...
