• Resumen

  • Rotational inertia is one of the most challenging topics in the first-year physics course. In the calculus-based AP Physics C course, rotational inertia comprises up to 20% of the AP mechanics exam1 and often comprises the most challenging Free Reponse Question on the AP exam. Specifically, rotational inertia’s heavy reliance on integral calculus makes it a standout unit in the introductory physics course since students often learn the required calculus concurrently or even after learning rotational inertia. The combination of challenging conceptual physics content and a reliance on more advanced math skills makes rotation an essential topic to focus on in order to build intuitive understanding. Consequently, the need exists for a high-quality and user-friendly rotational inertia lab that reinforces and strengthens students’ conceptual understanding of the topic.
