Systems and System Models
Knowledge
Students know:
- How to identify the system.
- Apply Newton's Second Law of Motion.
- What rotational inertia is and how it affects the motion of a rotating object.
Skills
Students are able to:
- Draw rigid body diagrams.
- Solve for net force.
- Extrapolate their understanding of a physical illustration of a phenomenon (e.g., spinning figure skater, merry-go-round) to an intangible example of the same phenomenon (e.g., rapidly spinning pulsar, supernova).
- Follow written and verbal instructions.
Understanding
Students understand that:
- Objects in rotational motion experience varied changes in motion depending upon their rotational inertia and the net force acting upon them.
