Question

Name the launcher.
Name the law on which its working is based.

Hint:

Newton’s Third Law is not only essential in rocketry but also explains many everyday phenomena, such as the recoil of a gun or the pushback when you jump off a boat.

Answer 1

Launcher: A rocket firecracker is typically launched using a simple guiding mechanism. This is often a bottle or a straight tube into which the rocket is placed, or simply the long stick attached to the rocket itself, which provides stability during its initial ascent. The purpose of the launcher is to ensure the rocket starts its flight in a vertical direction. Law: The working of a rocket is based on Newton’s Third Law of Motion. This law states that "for every action, there is an equal and opposite reaction." When the rocket’s fuel (gunpowder) burns rapidly, it produces a large amount of hot gas. These gases are expelled downwards at high velocity through a nozzle. This downward expulsion of gas (the "action") creates an equal and opposite upward force (the "reaction"), known as thrust, which propels the rocket into the air.
