Which law explains why a rocket moves forward by expelling gas backward?
A
Law of Conservation of Energy
B
Newton's Third Law
C
Ohm's Law
D
Law of Gravitation
Correct Answer: Option B — Newton's Third Law
Explanation:
Newton's Third Law explains rocket propulsion: as the rocket expels gas backward with force, the gas exerts an equal and opposite force push...
Newton's Third Law explains rocket propulsion: as the rocket expels gas backward with force, the gas exerts an equal and opposite force pushing the rocket forward. This action-reaction pair enables rockets to accelerate even in the vacuum of space.
