Rotational Inertia

The Rotational Inertia Concept Builder is all about comparing the rotational inertia of two situations. A short description and a diagram of each situation is provided and the learner must pay attention to details in order to determine which situation is characterized by the greatest rotational inertia. The Concept Builder consists of 24 total questions organized into 12 different Question Groups and spread across three Activities. In the first activity, Location, Location, Location, learners are presented two objects with the same mass but a different arrangement of the mass relative to the axis of rotation. In the second activity, A Change of Axis, learners are presented two identical objects with a different axis of rotation. In the third activity, Contraption Analysis, learners are presented a complex object with several identical-mass, connected parts that are arranged differently. Question-specific help is provided for each of the 12 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
