Question

A jet engine works on the principle of conservation of:

• A. Mass Velocity
• B. Angular Momentum
• C. Energy Mass
• D. Linear Momentum

Hint:

Jet engines operate by expelling high-speed gas, thus conserving linear momentum and generating thrust.

Answer 1

The Correct Option is D

A jet engine works on the principle of the conservation of linear momentum. According to Newton's third law of motion, the expulsion of gases from the jet engine results in a forward thrust, conserving the linear momentum of the system.
Thus, the correct answer is (D) Linear Momentum.
