equation of motion
51Fokker–Planck equation — [ thumb|A solution to the one dimensional Fokker–Planck equation, with both the drift and the diffusion term. The initial condition is a Dirac delta function in x = 1, and the distribution drifts towards x = 0.] The Fokker–Planck equation… …
52Orbit equation — In astrodynamics an orbit equation defines the path of orbiting body around central body relative to , without specifying position as a function of time. Under standard assumptions, a body moving under the influence of a force, directed to a… …
53Tanaka equation — In mathematics, Tanaka s equation is an example of a stochastic differential equation which admits a weak solution but has no strong solution. It is named after the Japanese mathematician Tanaka Hiroshi.Tanaka s equation is the one dimensional… …
54Tsiolkovsky rocket equation — Tsiolkovsky s rocket equation, or ideal rocket equation is named after Konstantin Tsiolkovsky, who independently derived it and published in his 1903 work [К. Э. Циолковский, Исследование мировых пространств реактивными приборами, 1903. It is… …
55Hagen-Poiseuille equation — The Hagen Poiseuille equation is a physical law that describes slow viscous incompressible flow through a constant circular cross section. It is also known as the Hagen Poiseuille law, Poiseuille law and Poiseuille equation.Equationtandard fluid… …
56Simple harmonic motion — is the motion of a simple harmonic oscillator, a motion that is neither driven nor damped. The motion is periodic, as it repeats itself at standard intervals in a specific manner described as being sinusoidal, with constant amplitude. It is… …
57Dirac equation — Quantum field theory (Feynman diagram) …
58Ordinary differential equation — In mathematics, an ordinary differential equation (or ODE) is a relation that contains functions of only one independent variable, and one or more of their derivatives with respect to that variable. A simple example is Newton s second law of… …
59Rational motion — In kinematics, the motion of a rigid body is defined as a continuous set of displacements. One parameter motions can be definedas a continuous displacement of moving object with respect to a fixed frame in Euclidean three space ( E 3), where the… …
60Debye–Hückel equation — The Debye–Hückel equation and Debye–Hückel limiting law, were derived by Peter Debye and Erich Hückel, who developed a theory with which to calculate activity coefficients of electrolyte solutions.[1] Activities, rather than concentrations, are… …
