The flight of a rocket in space is an example of
Correct answer: B. Third law of motion
- A. Second law of motion
- B. Third law of motion
- C. First law of motion
- D. Law of Gravitation
Explanation
The third law of motion, stating that for every action, there is an equal and opposite reaction, is directly applicable to a rocket's operation in space. The expulsion of gases downward creates an equal and opposite reaction, propelling the rocket upward.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
