the minimum velocity that a moving body (such as a rocket) must have to escape from the gravitational field of a celestial body (such as the earth) and move outward into space
The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 36,700 ft/s; 25,020 mph; 21,744 kn) at the surface.

The speed required by an spacecraft to leave the earth's gravitational pull is called escape velocity. It is about 11.2 km/s for the earth
