121-122-123 Courses

The PHYS 121-122-123 introductory physics sequence is targeted for students in physical sciences and engineering. Upon successful completion, students should be able to develop calculus-based models to describe the physical world and apply them to other fields of science and everyday phenomena. Each course consists of three major components: lecture laboratory, and tutorial.

Refer to the course offering page to see scheduled times and course instructors.

Course Material

You need to purchase the following items:

  • The Tutorial Coursepack
    • Only available from the University Bookstore.
    • This will be used to fill in your tutorial work and tutorial homework, so you cannot use a used one.
  • Access code for MyLab and Mastering
    • See purchasing options below
  • Textbook: Principles & Practice of Physics, by Mazur
    • We are transitioning from the 1st edition to the 2nd edition with a schedule as follows:
      • Autumn 2022: the 2nd edition is used in PHYS 121. The 1st edition is used in PHYS 122 and PHYS 123.
      • Winter 2023: the 2nd edition is used in PHYS 121 and 122. The 1st edition is used in PHYS 123.
      • Spring 2023: the 2nd edition is used in PHYS 121, 122, and 123.
    • The 1st and 2nd editions are almost identical in contents. The 1st edition comes in two books (“Principles” and “Practice”), but they are combined into one book in the 2nd edition. If you have a hard copy of the 1st edition, there is no need for you to obtain the 2nd edition.

Purchasing Options

  • UNIVERSITY BOOKSTORE OPTIONS for the 1st edition

    If you purchase the textbook from the University Bookstore, the access code is included.

    You have the following four purchasing options that include both textbook and the access code from the University Bookstore. Choose the one that best fits your need and budget. The 2-year access can be used for all the courses in the series, so you will not need to purchase access again.

    Option Access Duration eText Hardcopy Text
    A (Bookstore) 1 quarter Loose leaf
    B (Bookstore) 2 years Loose leaf
    C (Bookstore) 2 years Hardcover
    D (Bookstore) 2 years No
    The options labelled A through D above, correspond to the following descriptions at the University Bookstore.

    A.    3 P/S Phys 121 Only Loose Leaf Principles & Practice Of Physics (Custom) W/ Modified Masteringphysics
    B.    3 P/S Loose Leaf Principles & Practice Of Physics W/ Modified Masteringphysics
    C.    3 P/S Principles & Practice Of Physics W/ Modified Masteringphysics
    D.    Mastering Access w/eBook for Principles & Practices of Physics - Multi Term

    Note that the order of the options shown above may be different from those shown at the University Bookstore.
  • ALTERNATIVE OPTIONS for the 1st edition

    If you do not purchase the textbook from the University Bookstore, you can purchase the access code online.

    During the steps in the access to the online homework system instructions you will be given the following three choices to purchase directly from Pearson. Choose the one that fits your need and budget. The 2-year access can be used for all the courses in the series, so you will not need to purchase access again.

    Option Access Duration eText Hardcopy Text
    E (Pearson) 2 years No
    F (Pearson) 2 years No No
    G (Pearson) 1 quarter No
    You need a textbook for this course, so if you choose option F you need to obtain a textbook elsewhere. Note that there is one hardcover textbook with a white cover titled “Principles and Practice of Physics” and another with a black cover titled “Principles and Practice of Physics”. If you do not purchase the textbook from the University Bookstore or Pearson, you might be missing the black copy, which includes the end-of chapter problems. But you have access to many of these problems through MyLab and Mastering.
