Question

what is escape velocity​

Answer 1

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. 

Answer 2

Answer:

The minimum velocity required by a satellite launcher, space shuttle, any launch vehicle or any other object to escape the constant gravitational downward pull by the Earth and never fall back again on Earth is known/called as the 'ESCAPE VELOCITY'.

Explanation:

The Escape Velocity for Earth is 11.2 km/s. It means that if an object wants to escape the gravitational force of Earth forever , then it must have a minimum velocity of 11.2 km/s.
