Which of the following is NOT TRUE?
Correct answer: D. Action and reaction can cancel each other
- A. Action and reaction have same nature
- B. Action and reaction have same line of action
- C. Action and reaction never act on same body
- D. Action and reaction can cancel each other
Explanation
Either force can be considered the action force or the reaction force. You might think that because action-reaction forces are equal and opposite that they cancel. However, action and reaction force pairs don't cancel because they act on different objects. Forces can cancel only if they act on the same object.

About Newton's Laws of Motion
Newton’s laws explain inertia, the relation between net force and acceleration, and action-reaction pairs. Questions involve free-body diagrams, balanced and unbalanced forces, F = ma, force as the rate of change of momentum, and identifying genuine third-law pairs, which act on different bodies.
