  2. Potential energy - Wikipedia

    en.wikipedia.org/wiki/Potential_energy

    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 ...

  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 & direction of gravitational force experienced by a point mass m {\displaystyle m} , due to the presence of another point mass M {\displaystyle M} at a distance r {\displaystyle r} , is given by Newton's law of ...

  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. Mass–energy equivalence - Wikipedia

    en.wikipedia.org/wiki/Massenergy_equivalence

    Mass near the M87* black hole is converted into a very energetic astrophysical jet, stretching five thousand light years.. In physics, massenergy equivalence is the relationship between mass and energy in a system's rest frame, where the two quantities differ only by a multiplicative constant and the units of measurement.

  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. Negative energy - Wikipedia

    en.wikipedia.org/wiki/Negative_energy

    The negative-energy particle then crosses the event horizon into the black hole, with the law of conservation of energy requiring that an equal amount of positive energy should escape. In the Penrose process , a body divides in two, with one half gaining negative energy and falling in, while the other half gains an equal amount of positive ...

  8. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    For example, the sum of translational and rotational kinetic and potential energy within a system is referred to as mechanical energy, whereas nuclear energy refers to the combined potentials within an atomic nucleus from either the nuclear force or the weak force, among other examples.

  9. Scalar field - Wikipedia

    en.wikipedia.org/wiki/Scalar_field

    The force is a vector field, which can be obtained as a factor of the gradient of the potential energy scalar field. Examples include: Examples include: Potential fields, such as the Newtonian gravitational potential , or the electric potential in electrostatics , are scalar fields which describe the more familiar forces.
