Question

the motion of rocket is based on newton's law of motion

Answer 1

Sir Isaac Newton first presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" in 1686. His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.

In aerospace engineering, the principal of action and reaction is very important. Newton's third law explains the generation of thrust by a rocket engine. In a rocket engine, hot exhaust gas is produced through thecombustion of a fuel with an oxidizer. The hot exhaust gas flows through the rocket nozzle and is accelerated to the rear of the rocket. In re-action, a thrusting force is produced on the engine mount. The thrust accelerates the rocket as described by Newton's second law of motion.

Answer 2

Yes, the motion of rocket is based on newton's law of motion.

Explanation:

In a rocket, gases are produced by burning any flammable material which comes out in the form of a jet with very high velocity downwards.

These gases exert upward force on the rocket, causing the rocket to rise. The higher the velocity of the gas jet, the higher the rocket also rises with higher velocity.

Jet Airplane: In this too, the gas is released backwards in the form of jet by explosion. The gas moves the airplane by applying a reaction force, which makes the airplane move faster.

Note: The main difference between rocket and jet aircraft is that the rocket has oxygen supply inside to burn the fuel, while the jet plane contains fuel kerosene (paraffin), which gets oxygen from the atmosphere to burn. is. Therefore, the jet plane cannot be carried to the same height as a rocket, because there will not be oxygen due to lack of atmosphere.

This is how Newton's law helps understand the concept of Rocket example.
