Newton’s 3 rd Law of Motion • Whenever one object exerts a force on

Newton’s 3 rd Law of Motion • Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object. • “You can’t touch without being touched!”

Action Force, Reaction Force • Action and reaction forces are a pair. • They

Action Force, Reaction Force • Action and reaction forces are a pair. • They may be equal in size but opposite in direction. • This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

Action Force, Reaction Force • You constantly use actionreaction force pairs as you move

Action Force, Reaction Force • You constantly use actionreaction force pairs as you move about. • When you jump, you push down on the ground. • The ground then pushes up on you. It is this upward force that pushes you into the air.

Action Force, Reaction Force • When you walk forward, you push backward on the

Action Force, Reaction Force • When you walk forward, you push backward on the ground. • Your shoe pushes the Earth backwards, and the Earth pushes your shoe forward. • Earth has so much mass compared to you that it does not move noticeably when you push it. • If you step on something that has less mass than you do, like a skateboard, you can see it being pushed back.

Action Force, Reaction Force • The thrust of a race car pushing it forward

Action Force, Reaction Force • The thrust of a race car pushing it forward is the action force and the drag of a race car pulling it back is the reaction force. • The gravitational force is the action force pulling the car downward, and the reaction force is the ground pushing back up on the race car.
