Never let your students confuse action-reaction and balanced forces again! This problem set will get the job done.
Challenge your students to sketch and identify the action-reaction force pairs in each of the 18 scenarios included in this practice problem set. In includes an answer key with the table responses all filled out.
This is the perfect problem set to use as homework or in-class practice, and it does an excellent job of presenting the students with lots of different situations to consider. Eventually, the students see the pattern in how the action and reaction force are related due to the repetitive nature of considering "What performs it?" and "On what is it performed?" for both forces.
