The students should understand that the moment of inertia I depends on the distribution of mass of an extended body about an axis of rotation

Experiments

Here are experiments our science specialists have selected to support this IB* topic.

Conservation of Angular Momentum

Experiment #14 from Advanced Physics with Vernier — Mechanics

In this experiment, you will

  • Collect angle vs. time and angular velocity vs. time data for rotating systems.
  • Analyze the θ-t and ω-t graphs both before and after changes in the moment of inertia.
  • Determine the effect of changes in the moment of inertia on the angular momentum of the system.
