Moment of Inertia

  • ME14.1 Masses on a Rod (Moment of Inertia Comparison)

    (Moved from angular momentum page) Two weights are mounted on a rod, which spins about the handle in its center. A hanging weight causes the system to rotate, and the position of the weights determines the angular acceleration.

  • ME14.2 Assorted Masses Rolling on Inclined Plane     InclinedPlane

    Disks and cylinders of different material, sizes, and shapes are rolled down an inclined plane. The initial energy is the same for all materials if started from the same height, and the final energy should also be the same. However, the moment of inertia differs from object to object. Students can predict outcomes of a race between different mass distributions.
