Escape velocity on the surface of the Earth (about 11 km/sec) is the velocity required for escaping Earth if no additional thrust is generated after the moment it leaves the surface. If you would throw a ball straight up, it would need to go that fast in order to never come back, if you can’t manage to throw it up that fast, it may get very high, but it will always fall back. (I am not taking air-resistance into account, in order to keep it simple). A rocket doesn’t need 1) to escape Earth, just get in orbit, which you can think of to be a balance between gravity and centrifugal force (which doesn’t really exist, but again: we’re keeping it simple), and b) to have escape velocity, since it will keep burning it’s engine, and this way will keep accelerating…


You should see Escape Velocity as a characteristic of your situation, not something you actually need to achieve…

The rocket will not be able to escape very far from earth's gravitational pull
