a rocket launching is an example of newtons _ law
The Correct Answer and Explanation is:
A rocket launching is an example of Newton’s Third Law of Motion.
Explanation
Sir Isaac Newton’s Third Law of Motion states: “For every action, there is an equal and opposite reaction.” This law is clearly demonstrated during a rocket launch.
When a rocket is set to launch, its engines burn fuel and expel exhaust gases downwards at high speed through the nozzle. This expulsion of gases is the action. According to Newton’s Third Law, an equal and opposite reaction occurs — the rocket is pushed upwards with a force equal in magnitude but opposite in direction to the downward thrust of the gases.
The rocket engine works on the principle of thrust. In the combustion chamber, fuel and oxidizer mix and ignite, producing hot gases. These gases rapidly expand and are forced out through the narrow nozzle at the base of the rocket. As the gases shoot downwards, they push the rocket body upwards. This upward push is what overcomes Earth’s gravity and causes the rocket to lift off.
It’s important to note that a rocket can launch in space as well, where there is no atmosphere. This is because Newton’s Third Law doesn’t depend on air or any external surface — it’s about forces between the rocket and the gases it expels. The law applies in a vacuum just as well as on Earth.
Rocket launches are among the most powerful and visually clear demonstrations of Newton’s Third Law. Without this principle, space exploration would not be possible. Engineers carefully calculate the amount of fuel needed to generate enough action (thrust) to produce the necessary reaction (lift-off and acceleration) to escape Earth’s gravitational pull.
In conclusion, every rocket launch showcases Newton’s Third Law of Motion in action, as it uses the principle of equal and opposite forces to propel itself skyward.
