Velocity-addition formula — In physics, a velocity addition formula is an equation that relates the velocities of moving objects in different reference frames. Contents 1 Galilean addition of velocities 2 Special theory of relativity 3 Derivation … Wikipedia
Velocity — In physics, velocity is defined as the rate of change of position. It is a vector physical quantity; both speed and direction are required to define it. In the SI (metric) system, it is measured in meters per second: (m/s) or ms 1. The scalar… … Wikipedia
Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… … Wikipedia

Angular velocity — Do not confuse with angular frequency The unit for angular velocity is rad/s.In physics, the angular velocity is a vector quantity (more precisely, a pseudovector) which specifies the angular speed, and axis about which an object is rotating. The … Wikipedia
E Matrix — The E Matrix is a paintball marker. In 1999 AirTech Industries, a company distributing through Diablo Direct, had developed a high end paintball gun named the Matrix. The Matrix was initially designed to be available in both a pneumatic and… … Wikipedia
Escape velocity — In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation,:U g = frac{ Gm 1m 2}{r}.It is commonly described as the speed needed to … Wikipedia
Angular velocity tensor — In physics, the angular velocity tensor is defined as a matrix T such that::oldsymbolomega(t) imes mathbf{r}(t) = T(t) mathbf{r}(t) It allows us to express the cross product:oldsymbolomega(t) imes mathbf{r}(t) as a matrix multiplication. It is … Wikipedia
Orthogonal matrix — In linear algebra, an orthogonal matrix (less commonly called orthonormal matrix[1]), is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors). Equivalently, a matrix Q is orthogonal if… … Wikipedia
Oberheim Matrix synthesizers — Oberheim Matrix 1000 Oberheim Matrix synthesizers are a historic product line of analog synthesizers from Oberheim featuring a method of synthesis which Oberheim called Matrix Modulation as a method of defining preset and user patches. While the… … Wikipedia
Foucault Pendulum vector diagrams — Several vector diagrams are often used to demonstrate the physics underlying the Foucault pendulum.Diagrams are provided to illustrate a pendulum located at the North Pole, equator, and 45 degrees N to show how the rotation of Earth in relation… … Wikipedia
