## Chapter 5: Newton's Laws of Motion

### Study Plan

The concepts presented in Chapter 5 describe forces and predict accelerations. Consider these questions as you begin your studies:

• What force must the floor of an elevator apply to your feet to accelerate you upward? (Checkup 5.4, question 6, page 143; and Example 6, page 147)
• How do an elevator and its counterweight accelerate if the cable connecting them is permitted to run freely? (Example 10, page 154)
• What devices are installed on elevators to ensure their safety? (Physics in Practice: Elevators, page 157)

#### Organize

1. Prepare for lecture by reading the assigned sections from Chapter 5 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 “Free-Body” Diagrams 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.
