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.

Introduce your students to combining force vectors to determine the net force acting on an object. Here are 10 essential practice problems with a key! Adaptable to virtually any grade level where this skill needs developed!

Interpreting free body diagrams to determine which forces are balanced and which are not. Students are tasked with determining and drawing the net force and acceleration vectors. 9 Practice problems in total. Answer key included! This activity is flexible in that the teacher may provide object masses and write force quantities on the vectors and require the students to calculate the acceleration of the object.
