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

druga kosmička brzina


Definition from Wikipedia:
Друга космичка брзина (параболичка брзина, брзина oслобађања) је најмања брзина коју је потребно дати објекту (чија маса је занемарљива у односу на масу планете од које одлази) да би објект напустио гравитационо поље планете.

Example sentence(s):
  • Ako se materija i dalje kontrahuje, gravitacija raste i dolazi do nivoa kada se druga kosmicka brzina povecava na brzinu svetlosti (c). Kada se to dogodi vrednost precnika tela je jednaka Svarcsildovom radijusu, odnosno formira se crna rupa. - Astronomija  
  • Za svako nebesko telo postoji tzv. druga kosmička brzina, a koja zavisi od mase odredjenog tela. Za Zemlju iznosi oko 8 km/s, a za Sunce oko 250 km/s. Ako neki objekat kao početnu brzinu ima drugu kosmičku brzinu moći će da napusti dato nebesko telo i da se oslobodi njegove gravitacije. - Svemir, život i još nešto  
  • Иако је основна замисао која их описује стара више од два века (енглески научник Џон Мичел је 1783. у својој расправи звезде масивније од Сунца, код којих је друга космичка брзина већа од светлосне, па њихова гравитација враћа светлост, назвао тамним звездама), назив је први употребио амерички физичар Џон Вилер 1969. - Politika online
