Space Technology & Education Educator Interview Questions and Answers

The principle of a rocket is based on Newton's third law of motion.

• A rocket works by expelling high-speed exhaust gases in one direction, which generates a reactive force in the opposite direction.

• This reactive force propels the rocket forward.

• The principle is described by Newton's third law of motion: for every action, there is an equal and opposite reaction.

• The exhaust gases are expelled through a nozzle at the rear ...read more

Newton's three laws describe the fundamental principles of motion.

• First law (Law of Inertia): An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.

• Second law (Law of Acceleration): The acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its ...read more
