Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
Every conservative force has a potential energy. By following two principles one can consistently assign a non-relative value to U: Wherever the force is zero, its potential energy is defined to be zero as well. Whenever the force does work, potential energy is lost.
There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is ...
Chemical energy is the kind of potential energy "stored" in chemical bonds and is studied in chemistry. [24] Nuclear energy is energy stored in interactions between the particles in the atomic nucleus and is studied in nuclear physics. [25] Electromagnetic energy is in the form of electric charges, magnetic fields, and photons.
Energy principles in structural mechanics express the relationships between stresses, strains or deformations, displacements, material properties, and external effects in the form of energy or work done by internal and external forces.
Another class of machine-learned interatomic potential is the Gaussian approximation potential (GAP), [87] [88] [89] which combines compact descriptors of local atomic environments [90] with Gaussian process regression [91] to machine learn the potential energy surface of a given system.

In classical physics, a spring can be seen as a device that stores potential energy, specifically elastic potential energy, by straining the bonds between the atoms of an elastic material. Hooke's law of elasticity states that the extension of an elastic rod (its distended length minus its relaxed length) is linearly proportional to its tension ...
