Chapter 3. Review and Practice

Review the chapter objectives so that you'll know what the teacher expects you to learn from the chapter.

Chapter 3 Objectives

  1. Know how to represent vectors both graphically and mathematically.
  2. Know the difference between scalars and vectors.
  3. Be able to determine the magnitude and direction of a vector.
  4. Be able to determine the components of a vector.
  5. Know how to add and subtract vectors both graphically and algebraically.
  6. Be able to represent position, displacement, velocity, and acceleration as two-dimensional vectors.

  E.3.1. Chapter 3 Review and Practice

About trigonometry: Since we start doing physics in 2 dimensions in Chapter 3, you'll need to start using trig functions in your work. If you need a review or feel shaky in your use of trigonometry, see this guide: Trigonometry: Math for 2-Dimensional Physics.

You should now be very familiar with these study aids, since you've used similar ones for Chapters 1 and 2.

  1. Click here to open the review pages in a new window.  Study these pages as needed to refresh your memory about the material.

  2. Click here to open the set of Practice Questions. These questions not only provide practice with vectors, but they provide review of the concepts of displacement, velocity, and acceleration and their graphical representations. Note that questions 4, 23, 24, and 25 relate to the optional section 3-6 and are not required. You may also omit questions 6, 10, 11, and 14.

  3. Click here to open the set of Practice Problems. Do problems 1 - 4. These problems provide practice in computing components and magnitudes of vectors. Copy and paste the Results Reporter window into BrainHoney as you've done in the past.
