Question

What do you mean by Escape velocity?

Answer 1

The body when hitted with a speed of 11.2 km/sec then it is called escape velocity.
By this an object cannot come back to earth.

Answer 2

➡In physics escape velocity is the minimum speed needed for a free object to escape from the gravitational influence of a massive body.

➡The escape velocity from Earth is about 11.186 km/s (40,270 km/sec) at the surface.


↪Basically :--

➡The minimum velocity that a moving body such as a rocket must have to escape from the gravitational field of a celestial body and move outward into space.

➡Its value is G . The unit for escape velocity is meters per second (m/s)


➡The earth escape velocity is highest or more under the astroid belt's planet
