Question

People often say “For every action, there is an equivalent opposite reaction”. Here they meant ‘action of a human’. Is it correct to apply Newton’s third law to human actions? What is mean by ‘action’ in Newton's third law? Give your arguments based on Newton’s laws.

Short/Brief Note

Solution

Newton’s third law is applicable to only human’s physical actions which involve physical force. The third law is not applicable to a human’s psychological actions or thoughts.
