Rocket engines operate on the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. By expelling high-speed exhaust gases in one direction, the rocket experiences a reactive force in the opposite direction, propelling it forward.

Why only rocket engine propelled to space?
Rocket engines are primarily used for space propulsion because they operate on the principle of Newton's third law of motion: for every action, there is an equal and opposite reaction. They expel mass at high speed, generating thrust that can overcome Earth's gravity. Unlike jet engines, which rely on atmospheric oxygen, rocket engines carry both fuel and an oxidizer, allowing them to function in the vacuum of space. This capability makes them essential for launching payloads beyond Earth’s atmosphere.
How can a rocket in space shut off its engines and still keep moving?
A rocket in space can shut off its engines and still keep moving due to the principle of inertia. Once the engines are turned off, the rocket will continue to move forward at a constant velocity unless acted upon by another force, such as gravity or a change in trajectory.
How many rocket engines did the Saturn V have?
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
How rocket ship take off?
A rocket ship takes off by igniting its rocket engines, which produce thrust that propels the ship upward. The force generated by the rocket engines pushes the ship off the ground and into the air, overcoming Earth's gravity. As the rocket ascends, its engines continue to provide thrust to propel it further into space.
What controls the thrust of a rocket?
Liquid rocket engines would act much like a car engine. More fuel, more thrust. Solid rocket engines are either on or off. No throttle control.
What type of engine powers a rocket?
Rockets are powered by rocket engines, which operate on the principle of propulsion through the expulsion of high-speed exhaust gases. There are two main types of rocket engines: liquid rocket engines, which burn liquid propellants, and solid rocket engines, which use solid propellants. These engines generate thrust based on Newton's third law of motion, where the expulsion of gas in one direction propels the rocket in the opposite direction. Additionally, some rockets may employ hybrid engines that combine both liquid and solid propellants.
Are vehicle made on principle of thermodynamics?
That's how engines operate.
What are two main types of rocket engines?
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
What is the difference between jet engines and spaceships?
Jet engines operate by drawing in air, compressing it, mixing it with fuel, and igniting the mixture to produce thrust, relying on atmospheric oxygen for combustion. In contrast, spaceships use rocket engines, which carry both fuel and an oxidizer, allowing them to operate in the vacuum of space where there is no air. This fundamental difference allows jet engines to function within Earth's atmosphere, while rocket engines are designed for the challenges of space travel. Additionally, rocket engines typically generate much higher thrust to escape Earth's gravitational pull.

How do the principles of a water bottle rocket relate to real rockets?
Thy operate on the same principle. The water going backwards has momentum that is balanced by the rocket going forward.
How can a rocket in space shut off its engines and still keep moving?
A rocket in space can shut off its engines and still keep moving due to the principle of inertia. Once the engines are turned off, the rocket will continue to move forward at a constant velocity unless acted upon by another force, such as gravity or a change in trajectory.
How does a rocket use lift and thrust?
Rockets use thrust generated by their engines to push them forward and overcome gravity. They do not rely on lift as traditional airplanes do, as they operate in the vacuum of space. The propulsion from the engines creates the necessary force to lift the rocket off the ground and into space.
Why only rocket engines can be propelled to space?
Rocket engines are not air breathing engines and hence they can be propelled into space.
What is rocket cryogenic engines?

Working principle of rocket engine?
A rocket engine, or simply "rocket," is a jet engine[1] that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.Rocket engines as a group, have the highest exhaust velocities, are by far the lightest, and are the most energy efficient (at least at very high speed) of all types of jet engines. However, for the thrust they give, due to the high exhaust velocity and relatively low specific energy of rocket propellant, they consume propellant very rapidly.
How many rocket engines did the Saturn V have?
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
