The third law of motion explains:
Correct answer: D. The existence of a pair of forces in nature
- A. The effect of force
- B. The existence of a force
- C. The existence of two forces
- D. The existence of a pair of forces in nature
Explanation
According to the third law all the actions have reactions that's why any force does not occur as a single it will be affected by the other force too that's why forces are present in the form of pairs. Therefore, option D is correct.

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.
