What is rocket propulsion and how does it work?

What is rocket propulsion and how does it work?

Rocket propulsion is a method of moving a rocket by expelling mass at high speed. It works on Newton's third law of motion: for every action, there is an equal and opposite reaction.

What are the main types of rocket propulsion?

The main types of rocket propulsion include chemical propulsion, electric propulsion, and nuclear thermal propulsion.

Can you explain how chemical propulsion works?

Chemical propulsion works by burning fuel and oxidizer to produce hot gases that are expelled through a nozzle, generating thrust.

What are the advantages of electric propulsion?

Electric propulsion is more efficient than chemical propulsion, allowing spacecraft to travel longer distances with less fuel.

What are some real-world applications of rocket propulsion?

Rocket propulsion is used in space exploration, satellite launches, and even in some military applications.
