Teaching Resources
Main Topics
- Rotation
- Torque
- Moment of Inertia
- Angular Momentum
Sample Learning Goals
- Determine the relationship between the applied force, frictional force (of the brake) and the torque
- Write an equation that relates the torque required to the radius at which the force is applied
- Describe in your own words the relationship between torque and the moment of inertia
- Write an equation that relates the moment of inertia to the angular velocity
- Show that Angular momentum is conserved with examples of a bug traveling on a rotating platform.
