Newton’s Third Law in Action

Newton's third law states that for every action there is an equal and opposite reaction.

This means when you push against a wall, the wall pushes back with the same

force. When a rocket expels gas downward, the gas pushes the rocket upward.

When you jump, you push the Earth down and it pushes you up. This principle explains

why guns recoil when fired and why swimmers push water backward to move forward.

Understanding this law helps us predict how objects interact in every physical situation.
