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 sentences:
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)

Antrasis kosminis greitis arba Pabėgimo greitis
Definition from
Vikipedija:
Antrasis kosminis greitis arba Pabėgimo greitis – greitis, kurį turi pasiekti mažos masės kūnas, kad jo kinetinė energija būtų lygi gravitacinei potencinei energijai, ir, kad įveikęs didesnės masės kūno gravitacijos lauką, iš jo ištrūktų.
Example sentences:
Kad erdvėlaivis patektų i tarpplanetinę erdvę, jam reikia suteikti parabolinį greitį $ v_p = v_a sqrt 2 $ arba dar didesnį. Ties Žemės paviršiumi parabolinis greitis $ v_p = v_{2k} = v_{1k} sqrt 2 = 11,19 $ km/s. Toks greitis ($ v_{2k} $) vadinamas antruoju kosminiu (arba pabėgimo) greičiu Žemės atžvilgiu. (Mokslasplius)
Pasiekęs antrąjį kosminį greitį, mažos masės kūnas įveikia didesnės masės kūno gravitacijos lauką ir iš jo ištrūksta (pabėgimo greitis) (astronomija.lt)
