equation of motion
81Parametric equation — butterfly curve. In mathematics, parametric equations are a method of defining a curve. A simple kinematical example is when one uses a time parameter to determine the position, velocity, and other information about a body in motion.Abstractly, a …

83Constant of motion — In mechanics, a constant of motion is a quantity that is conserved throughout the motion, imposing in effect a constraint on the motion. However, it is a mathematical constraint, the natural consequence of the equations of motion, rather than a… …
84Brownian motion — Any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for Robert Brown, who was investigating the fertilization process of flowers in 1827 when he noticed a rapid oscillatory… …
85Differential algebraic equation — In mathematics, differential algebraic equations (DAEs) are a general form of (systems of) differential equations for vector–valued functions x in one independent variable t, where is a vector of dependent variables and the system has as many… …
86quadratic equation — Math. an equation containing a single variable of degree 2. Its general form is ax2 + bx + c = 0, where x is the variable and a, b, and c are constants (a non zero). [1680 90] * * * Algebraic equation of particular importance in optimization. A… …
87Laplace's equation — In mathematics, a partial differential equation whose solutions (harmonic functions) are useful in investigating physical problems in three dimensions involving gravitational, electrical, and magnetic fields, and certain types of fluid motion.… …
88Retrograde motion — This article is about retrograde motions of celestial bodies relative to a gravitationally central object. For the apparent motion as seen from a particular vantage point, see Apparent retrograde motion. Retrograde orbit: the satellite (red)… …
