Today's rockets use chemical fuel for this. That is, they burn something.
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.
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.
If a rocket rises from Earth but never attains escape velocity, it will eventually fall back to Earth due to gravity. The rocket's upward thrust will not be enough to overcome Earth's gravitational pull, causing it to return to the planet's surface.
It takes around 8 minutes for a rocket to reach space and escape Earth's atmosphere. This can vary slightly depending on the specific rocket and its speed.
If the rocket has a certain speed, it will escape from gravity due to its own momentum. To speed the rocket up, currently chemical combustion is used. The burning gas goes out in one direction, thus pushing the rocket in the opposite direction.If the rocket has a certain speed, it will escape from gravity due to its own momentum.

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.

they have to pass some forces in the earths atmosphere They have to overcome the force of gravity, lifting the rocket and all of the fuel to an escape orbit.
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.
no. They are carried in a rocket of some description, then released
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.
