LaoA rocket launch demonstrates Newton's third law of motion when the rocket propels itself upward by expelling exhaust gases downward. As the rocket fires its engines, it pushes the exhaust gases downward with a force. Simultaneously, the gases pushing downward create an equal and opposite force that propels the rocket upward, following Newton's third law that every action has an equal and opposite reaction.

Rocket works on the principal of conservation of?
newtons law of motion
Which of newtons laws explains the achievement of lifting a rocket off the ground and into space?
Newton's Third Law. Equivalent to Conservation of Momentum. By Newton's Third Law, if the gas is pushed out of the rocket, the gas pushes the rocket back, in the opposite direction.
Which one of newtons laws allows a rocket to function in space?
A rocket launching into space is a classic example of Newton's Third Law. The other two apply, but it is because of Newton's Third law that a rocket can launch into space. When the rocket engines fire, large amounts of gas escapes from the nozzle at high speed. This requires signifigant force to launch these gasses. Since Newton's Third Law states that for every action, there is an equal and opposite reaction, we know that the gas pushes back up on the rocket with just as much force as the rocket pushes down on the gas. This force launches the rocket into space.It's also shows Newtons law number 1."An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force."If you don't ignite the rocket motor (The unbalanced force), nothing happens.The rocket pushes into the ground at -9.81 metres per second and the Earth Pushes up at +9.81 metres per second. When you ignite the rocket this stable force becomes unbalanced by the thrust produced by the rocket motor and if the motor thrust exceeds the mass of the rocket the rocket will rise.And number 2..."Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object)."Fuel, mass and thrust falls into this category. The heavier the rocket is the more thust you need the bigger or more efficient the engine needs to be and the more fuel you will need to provide the thrust.And number three you already know about but for completeness."For every action there is an equal and opposite re-action."The rocket ejects high speed gases down, therefore the rocket goes up.

As newtons first law is the part of newtons second law then why you study newtons first law?
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
