  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 profile (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Energy_profile_(chemistry)

    Energy profile (chemistry) In theoretical chemistry, an energy profile is a theoretical representation of a chemical reaction or process as a single energetic pathway as the reactants are transformed into products. This pathway runs along the reaction coordinate, which is a parametric curve that follows the pathway of the reaction and indicates ...

  4. 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 ...

  5. Morse potential - Wikipedia

    en.wikipedia.org/wiki/Morse_potential

    The Morse potential, named after physicist Philip M. Morse, is a convenient interatomic interaction model for the potential energy of a diatomic molecule.It is a better approximation for the vibrational structure of the molecule than the quantum harmonic oscillator because it explicitly includes the effects of bond breaking, such as the existence of unbound states.

  6. Interatomic potential - Wikipedia

    en.wikipedia.org/wiki/Interatomic_potential

    Interatomic potential. Typical shape of an interatomic pair potential. Interatomic potentials are mathematical functions to calculate the potential energy of a system of atoms with given positions in space. [1][2][3][4] Interatomic potentials are widely used as the physical basis of molecular mechanics and molecular dynamics simulations in ...

  7. Feynman diagram - Wikipedia

    en.wikipedia.org/wiki/Feynman_diagram

    Feynman diagrams are often confused with spacetime diagrams and bubble chamber images because they all describe particle scattering. Feynman diagrams are graphs that represent the interaction of particles rather than the physical position of the particle during a scattering process. Unlike a bubble chamber picture, only the sum of all the ...

  8. Lennard-Jones potential - Wikipedia

    en.wikipedia.org/wiki/Lennard-Jones_potential

    Overview. The Lennard-Jones potential is a simplified model that yet describes the essential features of interactions between simple atoms and molecules: Two interacting particles repel each other at very close distance, attract each other at moderate distance, and eventually stop interacting at infinite distance, as shown in the Figure.

  9. 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 ...
