Newton's 3rd Law and Interaction Diagrams

Learning Goal 4.2- I can analyze motion within the framework of Newton's 3 Laws.

Prior to this week, I knew Newton's 3rd Law as "for every reaction there is an equal and opposite reaction". In class, I learned it more precisely as "all forces come in mutual interaction pairs". I also learned that the two forces in a 3rd Law pair cat on the different objects, are of the same type, and are equal and opposite. I was then able to apply this to interaction diagrams, which detail the forces acting between objects, as well as free body diagrams.
