Newton’s Third Law: Every Action Has a Reaction

The Famous Rule – Newton’s third law says every action has an equal and opposite reaction.
Push and Push Back – When you push on a wall, the wall pushes back on you with equal force.
Walking Made Possible – Your foot pushes the ground backward, and the ground pushes you forward.
Flight in Action – Birds flap wings down, and the air pushes them up—reaction makes flight possible.
Rocket Power – Rockets blast gas downward, and the equal reaction pushes the rocket upward into space.
Swimming Strokes – Swimmers push water back, and the water pushes them forward across the pool.
Jumping Off the Ground – Your legs push Earth down, and Earth pushes you up into the air.
Sports Examples – In basketball, the ball pushes your hand back as much as you push the ball forward.
Invisible Balance – Reactions happen instantly, making forces always paired, even if motion isn’t obvious.
A Universal Dance – From tiny atoms colliding to planets orbiting, action–reaction pairs shape the cosmos.
