Newton’s Third Law Of Motion

Newton’s Third Law of Motion.
For every action there is an equal and opposite reaction.
When we sit on a chair, our body exerts a downward force on the chair. The chair also exerts an upward force on the body.
If the chair would not have exerted a force, the chair would collapse and we would never be able to sit on a chair.
Newton’s third law of motion also helps birds to fly. Wings exert a downwoard force on the air. The air also exerts an equal and opposite force which pushes the bird upwards. This action reaction combination helps birds to fly in the air.
