In this activity, students will learn about Newton’s Third Law force pairs. Out of class, individual students will find an image of interest with two or more interacting objects. They will prepare free-body diagrams of the objects in the images and reflect on how the phrase “for every action, there is an equal and opposite reaction” applies to their image.
In class, students will be assigned to groups and each group will select a single image to work with. The groups will prepare free-body diagrams for the objects in the images, in both zero and non-zero acceleration, and will then present their results to the class for peer review. They will then compare and contrast the forces in the free-body diagrams. Finally they will prepare a short written heuristic on identifying Third Law force pairs.
This activity scaffolds the near transfer of concepts and deepens an understanding of 3rd Law force pairs.
Students will be able to:
