## Chapter 1: Space, Time, and Mass

### Study Plan

With the definitions of the units of distance and time given in Chapter 1, we can consider the following questions:

• How far does light travel in a small fraction of a second? (Example 1, page 10)
• How is the precision of the distance determination limited by the precision of the time measurement? (Example 3, page 15)

#### Organize

1. Prepare for lecture by reading the assigned sections from Chapter 1 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 Units and Significant Figures from your textbook.
5. Review the Math Help box on Trigonometry of the Right Triangle from your textbook.

#### Learn

2. Access the Online Concept Tutorials given for this chapter. Tutorials use animation and interactive exercises to help develop your understanding of fundamental topics.
