Newton's Third Law

                    NEWTONS THIRD LAW OF MOTION is if there is an action then there would be an equal reaction force. In other words if something moves there will always be at least one more thing moving. An example of his third law would be a bird flapping its wings.                                                                           

The bird is flapping its wings down while the air molecules are pushing back up and that is why when the bird flaps its wings it goes up.
