Forces work in pairs and act on objects to make them move. Think about a boy riding his scooter. To start moving, the boy pushes his foot on the ground. The Earth responds with an equal but opposite force on his foot. The result of the pair of forces is that the boy and his scooter move. Describe the pair of forces.
What is "The boy's push with his foot is the action force, and the pressure from the Earth is the reaction force."
