English term or phrase: escape speed
Definition from physics.fortlewis.edu:
The speed necessary for an object to escape the gravitational pull of an object. Anything that moves away from the object with more than the escape speed will never return.

Example sentence(s):
  • When an object is traveling exactly at escape speed, it is in a parabolic orbit with the body at the focus of the parabola. A parabolic path is open; hence an object following such a path will never return to the body. Conservapedia
  • Black holes, having infinite density, have an infinitely large escape speed. But it turns out that the escape speed value depends on how far an object is from a body of mass. So there is a certain distance from a black hole where the escape speed just equals the speed of light. Are black holes real?
  • One somewhat counterintuitive feature of escape velocity is that it is independent of direction, so that "velocity" is a misnomer; it is a scalar quantity and would more accurately be called "escape speed". Space Wiki

flykthastighet


Definition from Wikipedia:
Flykthastigheten är den hastighet som ett föremål som befinner sig på ett visst avstånd från en himlakropp måste ges för att det ska kunna färdas oändligt långt från himlakroppen utan att dras tillbaka av himlakroppens gravitation.

Example sentence(s):
  • Flykthastigheten är den hastighet som ett föremål som befinner sig på ett visst avstånd från en himlakropp måste ges för att det ska kunna färdas oändligt långt från himlakroppen utan att dras tillbaka av himlakroppens gravitation. - Wikipedia  
  • ■Den minsta hastighet en kropp måste tilldelas nära en himlakropps yta för att den sedan utan ytterligare drivkraft och utan hänsyn till atmosfärmotstånd skall oavbrutet avlägsna sig från himlakroppen, varvid alla andra himlakroppars gravitation, även solens, tänks utelämnade Vid jordytan är flykthastigheten ca 11,2 km/s - Ny Teknik
