The velocity of a any object to surpass the gravity of earth commonly known as escape velocity is 11.2Km/s.
the rocket speed required to escape out of the earth's gravity is known as escape velocity which is numerically equal to 11.2 km per sec.
Escape velocity is the speed that a rocket must reach to break free from Earth's gravity and enter space. It is the minimum velocity required for an object to overcome the pull of Earth's gravity.
A rocket that doesn't reach "escape velocity" will be overcome by gravity and will be pulled back down to Earth. Also, rockets which go into orbit have not reached escape velocity. Escape velocity is what is needed to completely leave earth's gravity well.
Exactly the same way it takes off from the earth. Gravity on the moon is so relativistically low that the propulsion required to reach an escape velocity is very very low compared to the earth.
A rocket gets out of Earth's orbit by achieving escape velocity, which is the speed needed to break free from the gravitational pull of Earth. The rocket's engines provide thrust to accelerate it to this speed, allowing it to overcome Earth's gravity and travel into deep space.
It can never escape it entirely. It can, however, travel fast enough that the increasing distance outweighs the effect of the decreasing gravity. On earth, this velocity is about seven miles per second.

Escape velocity.
If a rocket reaches escape velocity, it will be able to break free from a celestial body's gravitational pull and travel into space indefinitely without falling back to the surface. This velocity ensures that the rocket's kinetic energy is greater than the potential energy at that altitude, allowing it to overcome gravity's influence.
It isn't clear what exactly you mean with "escape gravity". The effects of Earth's gravity (for example) extend all the way to infinity, while getting weaker and weaker at a greater distance. So in a way, an object moving away from Earth never "escapes gravity". If an object moves fast enough - about 11.2 km/second near Earth's surface - it is said to have reached "escape velocity", in this case, it is fast enough never to come back. A rocket will reach escape velocity in a few minutes.
A single-stage rocket gets off the Earth by igniting its engines at liftoff, generating thrust that overcomes Earth's gravity. The rocket gains speed and altitude until it reaches the required velocity to enter orbit or escape the Earth's atmosphere.
