  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 ...

    en.wikipedia.org/wiki/Laws_of_thermodynamics

    If a system has a definite temperature, then its total energy has three distinguishable components, termed kinetic energy (energy due to the motion of the system as a whole), potential energy (energy resulting from an externally imposed force field), and internal energy. The establishment of the concept of internal energy distinguishes the ...

  4. Effective potential - Wikipedia

    en.wikipedia.org/wiki/Effective_potential

    The effective potential (also known as effective potential energy) combines multiple, perhaps opposing, effects into a single potential. In its basic form, it is the sum of the 'opposing' centrifugal potential energy with the potential energy of a dynamical system .

    Assuming the spacing between two ions is a, the potential in the lattice will look something like this: The mathematical representation of the potential is a periodic function with a period a. According to Bloch's theorem, [1] the wavefunction solution of the Schrödinger equation when the potential is periodic, can be written as:

  6. Newton's theorem of revolving orbits - Wikipedia

    en.wikipedia.org/wiki/Newton's_theorem_of...

    [2] [3] If the orbit rotates at an angular speed Ω, the angular speed of the second particle is faster or slower than that of the first particle by Ω; in other words, the angular speeds would satisfy the equation ω 2 = ω 1 + Ω. However, Newton's theorem of revolving orbits states that the angular speeds are related by multiplication: ω 2 ...

  7. Laplace–Runge–Lenz vector - Wikipedia

    en.wikipedia.org/wiki/Laplace–Runge–Lenz_vector

    By the inscribed angle theorem for circles, η is also the angle between any point on the circle and the two points of intersection with the p x axis, p x = ±p 0, which only depend on E, but not L. The conservation of the LRL vector A and angular momentum vector L is useful in showing that the momentum vector p moves on a circle under an ...

  8. Maxwell relations - Wikipedia

    en.wikipedia.org/wiki/Maxwell_relations

    It follows directly from the fact that the order of differentiation of an analytic function of two variables is irrelevant (Schwarz theorem). In the case of Maxwell relations the function considered is a thermodynamic potential and and are two different natural variables for that potential, we have

  9. Newtonian potential - Wikipedia

    en.wikipedia.org/wiki/Newtonian_potential

    When the measure μ is associated to a mass distribution on a sufficiently smooth hypersurface S (a Lyapunov surface of Hölder class C 1,α) that divides R d into two regions D + and D −, then the Newtonian potential of μ is referred to as a simple layer potential. Simple layer potentials are continuous and solve the Laplace equation except ...
