Physics of Rolling

This video discusses the physics of rolling objects that roll without slipping. The video will also discuss the differences in motion between a rolling disk and a rolling hoop based on the difference in rotational inertia.

The linked video covers the definition of rotational inertia, how to find it experimentally, how to calculate it from different equations, and include 2 example problems. Below are also three videos that allow you to investigate the relationship between the torque exerted on a system and the system’s angular acceleration. This is the experiment I use to introduce my students to the concept of rotational inertia. The linked conclusion discussion explains how the concept of rotational inertia is related to the collected data.
