Definition of escape velocity in English: escape velocitynoun The lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object. Example sentencesExamples - The work presented in these two papers formed the basis for a later study of black holes, showing that bodies of sufficiently large mass would have an escape velocity exceeding the speed of light and so could not be seen.
- If the object slows down below a minimum orbital velocity, it will hit the planet; if it speeds up beyond a maximum escape velocity, it will move away from the planet permanently.
- Both NASA and the Russian Space Agency were still playing around with chemical rockets, trying to beat the seventeen-thousand mile an hour escape velocity.
- The underlying concept is simple: the launcher accelerates the capsule to escape velocity.
- What would happen if the escape velocity of a planet were greater than the speed of light?
