I was wondering if there is an actual definition given by a recognised organisation over what is meant by the word "rocket". In case there is not, I wanted to reflect upon what do we really mean when we say rockets.
Why does it have to be oxidation? Why does it have to be a chemical reaction?Bandit127 said:I think we need to add the oxidiser to the fuel if we are to say it is a rocket.

I'm not sure it fits the definition, but maybe that's where the word "Rocket" came from. I understand that Neanderthals did hunt birds by throwing rocks, and they were in the process of developing a primitive language and grammar. It became a common battle cry when they attacked a flock of birds, "Rock It!"Hoophy said:I suppose a cannon could also act as a rocket.

This is a good question.jtbell said:Why do you think it might matter?
When I was younger we used a thing called a dictionary to answer such questions. Some dictionaries are produced by "recognised organisations". These days you make a few mouse clicks...Matt-STIPA said:I was wondering if there is an actual definition given by a recognised organisation over what is meant by the word "rocket".

A rocket is a vehicle or device that uses stored propellant to produce thrust and propel itself through the atmosphere or outer space.
The primary purpose of a rocket is to transport objects or humans to space. Rockets are also used for launching satellites, conducting scientific research, and exploring other planets.
There are several types of rockets, including solid fuel rockets, liquid fuel rockets, and hybrid rockets. Solid fuel rockets use a solid propellant, while liquid fuel rockets use a liquid propellant. Hybrid rockets combine elements of both solid and liquid propellants.
The main components of a rocket include the propulsion system, which produces thrust; the payload, which is the object or cargo being carried; the guidance system, which controls the direction and trajectory of the rocket; and the structure, which holds all the components together.
Rockets work based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The rocket's propulsion system produces thrust by expelling hot gases at high speeds, pushing the rocket in the opposite direction. This thrust propels the rocket through the atmosphere and into space.
