Question

Explain the mechanism of firing of rocket with help of Newton's third law of motion . Quality answer required .​

Answer 1

Answer:

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 thrust force just causes the rocket acceleration.

Answer 2

Newton's Third Law of Motion clearly states that for every action there is an equal and opposite reaction.

Consider two bodies A and B colliding. A exerts a force on B and this is called action. According to Newton's third law, B exerts an equal force on A but in the opposite direction. This is known as reaction.

Mechanism of firing of rocket :

When the fuel of a rocket is ignited, huge amounts of gases escape with high velocity through the opening N at the rare end. The force on the gases forms action. The burnt gases in turn exert a force, equal in magnitude but opposite in direction, on the rocket. This is the reaction force (Acceleration of the rocket keeps on increasing as the mass is constantly reduced due to the burning of the fuel).
