6. Newton’s Third Law A Case Study

7. Newton’s Third Law Research “Force Concept Inventory,” D. Hestenes, M. Wells and G. Swackhamer, Phys. Teach. 30, 141-158 (1992). This paper contains the Force Concept Inventory (FCI) and a detailed discussion of the Newtonian concepts it is constructed to probe. Results from administration of the FCI before and after instruction are given for some high school and university classes.
