Question
Explain : Newton’s third law of motion.

Answer

‘Every action force has an equal and opposite reaction force which acts simultaneously’.
  • Action and reaction are terms that express force.
  • These forces act in pairs. One force cannot exist by itself.
  • Action and reaction forces act simultaneously.
  • Action and reaction forces act on different objects. They do not act on the same object and hence cannot cancel each other’s effect.
