the The Physics Classroom
This website, from the Physics Classroom, offers a detailed physics tutorial for high school students explaining Newton's Third Law of Motion. The page gives a thorough description of action-reaction force pairs with illustrations and example exercises. Links are provided to tutorials on Newton's other laws of motion.
9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.

For any pair of interacting objects, the force exerted by the first object on the second object is equal in strength to the force that the second object exerts on the first, but in the opposite direction (Newton's third law). (6-8)
