Overview

Did you know that at a certain point on a moving wheel there's no motion? It's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Dr. Shini delves into the world of rotational motion!

    SC15.PHYS.4

    Identify and analyze forces responsible for changes in rotational motion and develop an understanding of the effect of rotational inertia on the motion of a rotating object (e.g., merry-go-round, spinning toy, spinning figure skater, stellar collapse [supernova], rapidly spinning pulsar).

    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.
