A rocket works on basis of:
Correct answer: C. Newton's 3rd law
- A. Newton's 1st law
- B. Newton's 2nd law
- C. Newton's 3rd law
- D. Newton's gravitational law
Explanation
The following is the solution: A rocket works on Newton's third law. Newton's third law states that for every action, there is an equal and opposite reaction. In the case of a rocket, the action is the force of the exhaust gases being expelled out of the back of the rocket. The reaction is the force that propels the rocket forward.

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.
