Question

The ‘rocket’ is a type of fire-cracker used in Diwali.

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

Answer 1

1. Name of Launcher: A cylindrical guide tube or stick acts as the launcher for a rocket fire-cracker. It helps maintain direction and stability during the initial motion.
2. Law: It is based on Newton's third law of motion, which states, “To every action there is an equal and opposite reaction.” When a rocket firecracker burns, the hot gases are released downward, creating an opposing force that pushes the rocket upward.
