Problem - Newton's Third Law
Newton's Third Law of Motion states that if two objects interact, the force F12 exerted by object 1 on object 2 is equal in magnitude and opposite in direction to the force F21 exerted by object 2 on object 1. Mathematically, F12 = - F21. In other words, all forces occur in an action/reaction pair ("for every action, there is an equal and opposite reaction").
Fill in the blanks in the table below. The first row is filled out as an example.
