Chapter 6: Further Applications of Newton’s Laws

Study Plan

Automobiles rely on the friction between the road and the tires to accelerate and to stop. We will see that one of two types of contact friction, kinetic or static, is involved. To see how these friction forces affect linear and circular motion, we ask:

  • In an emergency, an automobile brakes with locked and skidding wheels. What deceleration can be achieved? (Example 1, page 176)
  • What is the steepest slope of a street on which an automobile can rest without slipping? (Example 4, page 179)
  • When braking without skidding, what maximum deceleration can be achieved? (Example 5, page 180)
  • How quickly can a racing car round a curve without skidding sideways? (Example 10, page 186)
  • How does a banked curve help to avoid skidding? (Example 11, page 186)

Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 6 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 Friction Forces and Centripetal Forces from your textbook.

Learn

  1. Re-read Chapter 6 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.
