## Chapter 15: Oscillations

**Study Plan **

While learning about oscillating systems, we will consider such questions as:

- When the spring pushes and pulls the astronaut, what is the position of the astronaut as a function of time? The velocity of the astronaut? (Example 4, page 478)

- What is the total mechanical energy of the astronaut-spring system? What are the kinetic and potential energies as the spring begins to push? At later times? (Example 5, page 482)

- Good oscillators have low friction. How do we measure the quality of an oscillator? (Example 10, page 490)

#### Organize

- Prepare for lecture by reading the assigned sections from Chapter 15 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.

- 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.

- Review the
**Examples**from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.

- Review the
**Math Help**boxes on Derivatives of Trigonometric Functions and on Small-Angle Approximations for Sine, Cosine, and Tangent from your textbook.

#### Learn

- Re-read Chapter 15 and review your lecture notes.
- Access the
**Online Concept Tutorials**given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.Oscillations and Simple Harmonic Motion

Sections: 15.1Simple Pendulum

Sections: 15.4 - Use the FlashCards to test your memory for new key terms and equations.
- 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.

#### Connect

- Throughout the text
**Physics in Practice**boxes explore real-world applications of core concepts in specific detail. In Chapter 15 see:Physics in Practice: Chaos - Physics in the News offers additional real-world physics applications, and a daily dose of science-based news.
