4) On which Newton's law of motion the working of the rocket depends? Write the
principle of rocket launching in your words.
Answers
Answer:
The propulsion of all rockets is explained by the same physical principle: Newton's third law of motion. A rocket's acceleration depends on three major factors: the exhaust velocity, the rate the exhaust is ejected, and the mass of the rocket

Answer:
The working of a rocket depends on Newton's third law of motion .
The burring fuel inside the rocket creates a forward push on the rocket .This forward push creates an equal and opposite push on the exhaust gases. Thus, the working of a rocket depends on Newton's third law of motion.
Explanation:
A rocket can lift off from a launch pad only when it expels gas out of its engine. The rocket pushes on the gas, and the gas in turn pushes on the rocket. The whole process is very similar to riding a skateboard. Imagine that a skateboard and rider are in a state of rest (not moving). The rider jumps off the skateboard. In the third law, the jumping is called an action. The skateboard responds to that action by traveling some distance in the opposite direction. The skateboard's opposite motion is called a reaction. When the distance traveled by the rider and the skateboard are compared, it would appear that the skateboard has had a much greater reaction than the action of the rider. This is not the case. The reason the skateboard has traveled farther is that it has less mass than the rider.
