Audio: Isaac Newton developed several laws that aim to explain how the world works, specifically motion. This presentation looks at Newton's third law.

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

Audio: lets use the example of a rocket launching into space. The action is the gases being expelled from the rocket.

Audio: The reaction is the gas pushing back on the rocket, which launches the rocket up and into space.

Audio: Another example would be a baseball player hitting a baseball. Action- bat applies a force to the ball, reaction ball applies an equal force to the bat.

Audio: look at the motion in your life and try to identify the action/reaction forces.
