Question

A jet engine works on the principle of newton's.

• A. First law of motion
• B. Second law of motion
• C. Third law of motion
• D. None of these

Answer 1

The correct option is C

Third law of motion

Explanation:

1. A jet engine works on the principle of newton's third law of motion.
2. Newton's third law of motion states that for every action there is an equal and opposite reaction.
3. Newton’s third law of motion is the fundamental principle in a Jet plane. As a jet engine’s exhaust gas ignites back, the plane itself needs to move forward.
4. In simpler words, the action, the force of the exhaust gas shooting backward is equal and opposite to the reaction that is the force of the plane tending to move forward. The action moves the exhaust gas, while the reaction occurred moves the plane.

Hence, The correct answer is option C.
