Question

the motion of rocket is based on Newtons
law of motion
option & a) 1st law b) and law c) 3rd law
d none of above​

Answer 1

Answer:

Third law - A rocket works by expelling gases from one end at a very high velocity. The escaping gases have a very high speed and this with their mass translates to a very large momentum. Due to the principle of conservation of momentum the body of the rocket is pushed forward. If both the momentum of the gases as well as that of the rocket are added the sum is zero.

Answer 2

Answer:

• (c) 3rd law of motion

Correct Option:

• (c)

3rd law of Motion:

• Every action has an equal and opposite reaction

Explanation:

• Rocket motion is based on Newton's third law, which states that “for every action there is an equal and opposite reaction”.
• Hot gases are exhausted through a nozzle of the rocket and produce the action force.
• The propulsion of a rocket includes all the parts which make up the rocket engine; the tanks pumps, propellants, powerhead, and rocket nozzle.
• The function of the propulsion system is to produce thrust.
• The reaction force acting in the opposite direction is called the thrust force.
• Thrust is the force which moves a rocket through the air and through space.
• The thrust force just causes the rocket acceleration.
