Velocity overshoot — (auf deutsch ungefähr ‚Geschwindigkeitsüberhöhung‘) ist ein englischsprachiger Begriff aus der Festkörperphysik. Es beschreibt das Verhalten von Ladungsträgern in einem Halbleiter, wenn dieser einem äußeren elektrischen Feld ausgesetzt wird.… … Deutsch 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
Minimum mass — In astronomy, minimum mass is the lower bound calculated mass of observed objects such as planets, stars and binary systems, nebulae, and black holes. Minimum mass is a widely cited statistic for extrasolar planets. Because most extrasolar… … Wikipedia

Constant-velocity joint — Rzeppa six ball CV joint Constant velocity joints (aka homokinetic or CV joints) allow a drive shaft to transmit power through a variable angle, at constant rotational speed, without an appreciable increase in friction or play. They are mainly… … 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
Maunder Minimum — The Maunder minimum in a 400 year history of sunspot numbers The Maunder Minimum (also known as the prolonged sunspot minimum) is the name used for the period roughly spanning 1645 to 1715 when sunspots became exceedingly rare, as noted by solar… … Wikipedia
Escape Velocity (disambiguation) — Escape velocity is the minimum speed an object without propulsion needs to have to move away indefinitely from the source of the gravity field.Escape velocity may also refer to:* Escape Velocity (band) * Escape Velocity (Doctor Who), a Doctor Who … Wikipedia
escape velocity — Physics, Rocketry. the minimum speed that an object at a given distance from a gravitating body must have so that it will continue to move away from the body instead of orbiting about it. [1950 55] * * * Speed sufficient for a body to escape from … Universalium
