Question

define the escape velocity in brief​

Answer 1

Answer:

In physics (specifically, celestial mechanics), escape velocity is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to achieve an infinite distance from it. Speeds higher than escape velocity have a positive speed at infinity.
