A rocket is propelled into the air by the exhaust from burning fuel. As the exhaust leaves the back of the rocket, the rocket experiences an equal and opposite reaction, being pushed forward (upward). There does not have to be anything for the gases to push against, so rocket engines (with their own oxygen supply) can work in outer space as well as on Earth.
The only way for a rocket to reach an orbit around the Earth is by achieving a very high speed (escape velocity), so that its momentum carries it around the planet instead of falling back as missiles do.
The most advanced rockets work like their larger counterparts: solid fuel is burned inside a tube, and the exhaust gases rush out (down), pushing the rocket in the opposite direction (up).
Other rockets use pressurized water or carbon dioxide as propellants, again being released in the downward direction so that the opposite force is applied to lift the rocket.
Rockets propel themselves by expelling something opposite to the desired direction of travel. Expanding gas is the most common way to achieve this, but recently charged ions have been growing in popularity as a low thrust, high efficiency means of propulsion once in space.
a rocket goes into space really fast because gravity will pull it down otherwise so it has to get rid of the gravitational pull by travelling really fast. If the question is about propulsion, then Newton's third law comes into effect. By "throwing" gases out the back really fast, the rocket is pushed in the other direction. The more gas we throw and the faster we throw it, the faster we go.
This is quite a complicated subject.
You can try the Wikipedia page called "Rocket propellant". That's about the different types of rocket fuels.
There may be too much detail, but it gives a good idea of what is involved.
Rocket's work accordiing to Newton's third law That law is:A force is a push or a pull upon an object which results from its interaction with another object.
A solid or liquid propellant is typically oxidized, or burned inside a nozzle. The expansion of the fuel into the gaseous state provides thrust against the nozzle surface.
Rockets are powered by oxydation of liquid hydrogen fuel.
action - reaction principle.
by a chemical and a engine
The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets.
It is possible that it came from the russian italian or german
They use big fuel powered rockets that generate a huge amount of thrust to propel them.
rockets can go anywhere.space is where rockets can go
Rockets take off to carry things (called payloads) into space. Do you mean 'how' do rockets take off, or how do rockets work?
they were powered by gunpowder
Here's a rephrasing: How are rockets powered, by fuel? Yes, that's pretty much correct.
The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets.
By nuclear fuel

The first gunpowder-powered rockets were developed in Song China, by the 13th century.
Italy did not use rocket missile or rocket-powered aircraft in World War II. They may well have fired off mortar shells which were and are essentially rockets- but so did most of the combatants. Italy had some neat submarines, but not rockets.
Soyuz spacecraft are powered by Semyorka rockets.
