This quantity is subtracted from a related quantity to find the Lagrangian; those quantities are added to find the Hamiltonian. One form of this quantity is proportional to the square of the displacement of a spring; that (*) "elastic" type is given by one half k x squared, while the gravitational type is given by mgh. Denoted U, for 10 points, name this energy a physical system has because of its configuration, contrasted with kinetic energy.
