Add another layer to your investigation of rotational motion by integrating this activity designed for advanced high school and college physics.

The Centripetal Force Apparatus Moment of Inertia Accessory Kit is an excellent tool to expand the range of experiments and investigations with the Centripetal Force Apparatus or the Go Direct® Centripetal Force Apparatus. This accessory kit includes objects that can attach in different configurations to explore how the distribution of mass affects angular acceleration. It includes a ring and two disks, in addition to the beam that is included with our centripetal force apparatus.

We have created an activity for students to determine the moment of inertia of the various mass configurations.

Moment of Inertia Student Instructor
The initial slope of the angular velocity is used to determine angular acceleration.

The Moment of Inertia experiment provides instructions for setting up the equipment and then collecting and analyzing data. Students are guided through pre-lab activities designed to develop conceptual understanding that students use to make predictions. After conducting their investigations, the students compare the theoretical moments of inertia to their experimental values.
