Chapter 12: Rotation of a Rigid Body

Study Plan

The concepts of this chapter permit us to answer several questions about this centrifuge:

  • How are the speed and the centripetal acceleration at the end of an arm related to the rate of rotation? (Example 5, page 373)
  • How do we determine the resistance that the centrifuge offers to changes in its rotational motion? (Example 12, part (a), page 383)
  • How is the kinetic energy of the centrifuge arms related to the rate of rotation? (Example 12, part (b), page 383)
  • Organize

    1. Prepare for lecture by reading the assigned sections from Chapter 12 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
    2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
    3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.
    4. Review the Problem Solving Techniques box on Angular Momentum from your textbook.


    1. Re-read Chapter 12 and review your lecture notes.
    2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
    3. Use the FlashCards to test your memory for new key terms and equations.
    4. Work the end of chapter Problems and Review Problems assigned by your instructor. If your instructor has assigned SmartWork online homework, login from the right navigation pane.
