प्रश्न

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.

उत्तर

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.
