Which objects are interacting and in what direction do the respective forces point? Discuss both their directions and magnitudes! 1. A coffee cup sitting still on a table. the cup the table 2. Two boxes sitting on top of each other. the bottom box the top box 3.

Newton's Third Law of Motion states that "For every action, there is an equal and opposite reaction." This means that when two objects interact, they exert equal and opposite forces on each other. To identify Newton’s 3rd Law force pairs, it's essential to identify the objects that are interacting and in what direction the forces point. The first scenario, a coffee cup sitting still on a table, is an excellent example of Newton's Third Law. The coffee cup and the table are the two objects that are interacting. The coffee cup exerts a force downward on the table, and the table exerts an equal and opposite force upward on the coffee cup. This force keeps the coffee cup from falling through the table and supports the cup.
