What is a rocket?
1) A rocket is an engine or a vehicle that uses some form of energy to carry the payload to the destination
whether it is a space or the surface of the earth.
2) Rocket itself is a engine that works with the help of another engine.
How does a rocket work?
1) A rocket works on the principle of Newton’s third law of motion.
2) That is the rocket burns the fuel and produces the gas which is pushed backward. This gas pushes the
rocket forward. i.e., the law of action and reaction.
3) Rocket working similar to jet engine has a difference where a jet cannot travel in space and it can travel
only where the air is present. But a rocket can travel in space where there is no atmosphere.
4) Rockets use different types of fuels like solid rocket boosters, liquid fuel etc., and these fuels are filled
in the chambers which are burnt in the presence of an oxidized agent that produces hot gas.
Uses of Rockets:
1) Military – The rockets were first used in military to carry warheads to the destination and in wars.
2) Science and Research – Rockets are used as space probes, missiles etc., in this field
3) Space Flights
4) Technology
