Rocket Power

The action of gases coming out of the nozzles of a rocket at high speed produces
A reaction of equal force against the internal walls of the rocket, and this is
Force that propels it. That's why the rocket is the only one suitable.
The space travel device is completely autonomous and independent of any
External force by its power.

A plane should have air to stay in flight and provide the necessary oxygen
To make your fuel burn. But the rocket doesn't need anything. It doesn't need air to withstand.
And it carries its own oxidizer on board.

The force of reaction or thrust produced by a rocket engine is called thrust, and this
Power is expressed in terms of pounds. The thrust power of a rocket indicates how
A lot of weight is able to move on or near the surface of the Earth. If a
The particular rocket engine has a thrust of 100.000 pounds, this means that it can lift
Or propel so much weight.

Our missiles propelled by today's rockets operate like a bullet or an artillery.
Shell. The engines that "fire" burn only a few seconds, after that it's
Impulse that carries the rocket forward. For example in a minute forty
A 4.000-mile flight, an intercontinental ballistic missile is under the power of
Only about 200 seconds. The speed he's earned while his engines burned down.
Takes him in course until he finally loses momentum and, like an artillery
Shell, arches and falls to Earth. The course followed by a
Artillery or by a missile propelled by rocket while in flight is called
Its  "trajectory ".
