Question

what is escape velocity​

Answer 1

Answer:

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 eventually reach an infinite distance from it. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center.

Answer 2

Explanation:

In physics, 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 eventually reach an infinite distance from it. Escape velocity rises with the body's mass and falls with the escaping object's distance from its center.

Formula

v_e= \sqrt {\frac {2GM}{r}}

v_e = escape velocity

G = universal gravitational constant

M = mass of the body to be escaped from

r = distance from the center of the mass
