    "abstract": "We investigated students\u0027 use of Newton\u0027s second law in mechanics and\nelectromagnetism contexts by interviewing students in a two-semester\ncalculus-based physics course. We observed that students\u0027 responses are\nconsistent with three mental models. These models appeard in mechanics contexts\nand were transferred to electromagnetism contexts. We developed an inventory to\nhelp instructors identify these models and direct students towards the correct\none.",
