Newton's third law is derived from:
Correct answer: D. Newton's second law
- A. Newton's first law
- B. Both of these
- C. None of these
- D. Newton's second law
Explanation
Newton's second law tells us that Fnet = 0 and Newton's third law states that to every action, there is always an equal and opposite reaction. Mathematically, FAB = -FBA. When both forces, acting opposite, will be equal then the net force will be zero as implied by the second law.The diagram below simplifies Newton's third law of motion;

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.
