Newton’s Third Law A Case Study
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.
Newton’s Third Law Assessment Heavy student pushes light one Truck and car in head on collision Small car pushes Truck w/ dead engine
Two Force Probe Observations Add extra mass to one of the carts and allow them to collide in lots of ways. When does one cart exert more force on the other?
