Velocity — (dt. Geschwindigkeit) bezeichnet bei anschlagsdynamischen elektronischen Tasteninstrumenten (z. B. Synthesizer oder Keyboards) die sogenannte Anschlagsgeschwindigkeit, d. h. diejenige Geschwindigkeit, mit der eine Taste niedergedrückt… … Deutsch Wikipedia
Velocity of propagation — (VoP) or velocity factor (VF) is a parameter that characterizes the speed at which an electrical signal (e.g. radio) passes through a medium. Expressed as a number between 0 and 1 (or a percentage), it is the ratio of a signal s transmission… … Wikipedia
Four-velocity — In physics, in particular in special relativity and general relativity, the four velocity of an object is a four vector (vector in four dimensional spacetime) that replaces classical velocity (a three dimensional vector). It is chosen in such a… … Wikipedia
Mission characteristic velocity — The mission characteristic velocity (also mission velocity or characteristic velocity) is an important parameter describing space missions. It is the total velocity change needed (the sum of all maneuvers) to accomplish the mission, typically… … 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
One-parameter group — In mathematics, a one parameter group or one parameter subgroup usually means a continuous group homomorphism φ : R → G from the real line R (as an additive group) to some other topological group G. That means that it is not in fact a group … 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
Zero-velocity surface — The zero velocity surface is a concept that relates to the N body problem of gravity. The zero velocity surface is particularly significant when working with weak gravitational interactions among orbiting bodies.Galaxy clustersGiven a group of… … Wikipedia
