Examples of 3rd law of motion that states "for every action, there is an opposite and equal reaction.":
1.) When you punch a hard wall tremendously, you will soon feel pain after the opposite reaction applied on you when you exerted force on the wall.
2.) When playing seesaw, you will observe that when children play seesaw, one goes up, and one goes down. This is because when a child exerts force upward, it results to an equal force downward exerted on the other end of the seesaw.
3.) When you walk, you are actually exerting force on the ground backwards, as a result, your body moves forward.
4.) When birds fly, they are flapping their wings downward, exerting force in that direction so that their bodies will go upward as a result of the interaction.
