equation of motion hamugeš-e jonbeš Fr.: équation de mouvement 1) Any equation that describes the motion of objects, i.e., variation of
velocity, distance covered, acceleration, etc., as a function of time;
e.g., S = Vt + (1/2)at. ^{2}2) For a fluid, a relation, in its most fundamental form, equating the rate of change of momentum of a selected portion of fluid and the sum of all forces acting on that portion of fluid. 3) In quantum mechanics, an equation that governs the time variation of the → state of the
system. → Schrodinger equation. However, in the Heisenberg
formulation of quantum mechanics the equation of motion does not
involve the states, which in this case is time independent, but rather
the → observables of the system. |
