  2. Potential energy - Wikipedia

    en.wikipedia.org/wiki/Potential_energy

    e. In physics, potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. [1][2] The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, [3][4][5] although it has links to the ancient ...

  3. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    equal amount of energy in transit due to a displacement in the direction of an applied force. Transfer of material. equal amount of energy carried by matter that is moving from one system to another. A turbo generator transforms the energy of pressurized steam into electrical energy.

  4. Electric potential energy - Wikipedia

    en.wikipedia.org/wiki/Electric_potential_energy

    The electric potential energy of a system of point charges is defined as the work required to assemble this system of charges by bringing them close together, as in the system from an infinite distance. Alternatively, the electric potential energy of any given charge or system of charges is termed as the total work done by an external agent in ...

  5. Potential energy surface - Wikipedia

    en.wikipedia.org/wiki/Potential_energy_surface

    Potential energy surface. A potential energy surface (PES) or energy landscape describes the energy of a system, especially a collection of atoms, in terms of certain parameters, normally the positions of the atoms. The surface might define the energy as a function of one or more coordinates; if there is only one coordinate, the surface is ...

  6. Energy–momentum relation - Wikipedia

    en.wikipedia.org/wiki/Energy–momentum_relation

    Energy–momentum relation. In physics, the energy–momentum relation, or relativistic dispersion relation, is the relativistic equation relating total energy (which is also called relativistic energy) to invariant mass (which is also called rest mass) and momentum. It is the extension of mass–energy equivalence for bodies or systems with ...

  7. Elastic energy - Wikipedia

    en.wikipedia.org/wiki/Elastic_energy

    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. Elasticity theory primarily develops formalisms for ...

  8. Mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Mechanical_energy

    General. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy (which is measured by the position of the parts of the system) and the kinetic energy (which is also called the energy of motion): [1][2] The potential energy, U, depends on the position of an object subjected to gravity or some other ...

  9. Electric potential - Wikipedia

    en.wikipedia.org/wiki/Electric_potential

    v. t. e. Electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work / energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field. More precisely, the electric potential is the energy per unit charge ...
