Frey Scientific Moment of Inertia Ring and Disc Set is a fun and easy way to demonstrate moment of inertia and distribution of mass in rotating bodies. Metal and special plastic disc (with 15 inch diameter) and disc is allowed to roll down an incline together, creating a difference in their acceleration characteristics and in turn, demonstrating the important concepts of inertia.
  • Ring and disc apparatus provide a fun, fast, and easy way to have students practice and demonstrate moment of inertia and distribution of mass in rotating bodies
  • Roll the plastic ring of the same mass and diameter as metal ring on an inclined plane or level surface to witness a moment of inertia
  • Difference in both rings' acceleration can be studies to understand principles of rotating bodies and inertia
  • Mode of inertia ring and disc is a fun addition to science classes or STEM discovery centers
