How does Newton's third law apply to rocket engines?

Understand the Problem

The question is asking how Newton's third law of motion applies to rocket engines and provides four options to choose from that describe different scenarios related to this principle.

Answer

Newton's third law applies by producing thrust through action-reaction forces.

Newton's third law applies to rocket engines by stating that the action of expelling exhaust gases from the engine produces an equal and opposite reaction force, propelling the rocket forward.

Answer for screen readers

Newton's third law applies to rocket engines by stating that the action of expelling exhaust gases from the engine produces an equal and opposite reaction force, propelling the rocket forward.

More Information

This principle allows rockets to operate in the vacuum of space where they have no other means to push off from.

Tips

A common mistake is to think that rockets push against the air or ground to move. They rely solely on the reaction forces from expelling gases.
