  2. Potential energy - Wikipedia

    en.wikipedia.org/wiki/Potential_energy

    Potential energy is the energy by virtue of an object's position relative to other objects. [6] Potential energy is often associated with restoring forces such as a spring or the force of gravity. The action of stretching a spring or lifting a mass is performed by an external force that works against the force field of the potential.

  3. Gravitational energy - Wikipedia

    en.wikipedia.org/wiki/Gravitational_energy

    The gravitational potential energy is the potential energy an object has because it is within a gravitational field. The magnitude of the force between a point mass, M {\displaystyle M} , and another point mass, m {\displaystyle m} , is given by Newton's law of gravitation : [ 3 ] F = G M m r 2 {\displaystyle F={\frac {GMm}{r^{2}}}}

  4. Gravitational potential - Wikipedia

    en.wikipedia.org/wiki/Gravitational_potential

    The gravitational potential (V) at a location is the gravitational potential energy (U) at that location per unit mass: =, where m is the mass of the object. Potential energy is equal (in magnitude, but negative) to the work done by the gravitational field moving a body to its given position in space from infinity.

  5. Negative energy - Wikipedia

    en.wikipedia.org/wiki/Negative_energy

    Gravitational energy, or gravitational potential energy, is the potential energy a massive object has because it is within a gravitational field. In classical mechanics , two or more masses always have a gravitational potential .

  6. Mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Mechanical_energy

    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.

  7. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a ...

  8. Potential well - Wikipedia

    en.wikipedia.org/wiki/Potential_well

    A potential well is the region surrounding a local minimum of potential energy. Energy captured in a potential well is unable to convert to another type of energy (kinetic energy in the case of a gravitational potential well) because it is captured in the local minimum of a potential well. Therefore, a body may not proceed to the global minimum ...

  9. Thermodynamic potential - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_potential

    A thermodynamic potential (or more accurately, a thermodynamic potential energy) [1] [2] is a scalar quantity used to represent the thermodynamic state of a system.Just as in mechanics, where potential energy is defined as capacity to do work, similarly different potentials have different meanings.
