Policy on Missed Exams and Assignments


Primary textbook: “University Physics”, 13th Edition, authors Young & Freedman (Pearson 2012).  The E-text bundled together with access to the right (13th edition) homework assignments is sold under ISBN code 9780321741257 at the NJIT bookstore or on Pearson's web site.

We are not using the 14th or 15th editions of the text and homework system at this time.  Used hard copies of the text are available at the NJIT bookstore or online sources for those who want hard text.   

We use only Chapters 21 to 31 in this course; any version of the 13th edition containing Chapters 21 - 31 is OK. 

On-line Homework: Unaffected by COVID-19 Measures
Each student must acquire an access code and then enroll in the "Mastering Physics" course section that his/her instructor identifies via a course identifier code.  Homework assignments will be posted on-line in Mastering Physics. Students login, download and solve the assigned problems, and submit answers to the automated grading system.  

There is a newly released version of the homework system called "Modified Mastering Physics".  We are not using it, yet; We are using the original Mastering Physics platform reached using the following login url:


The Mastering Physics Course Identifier Codes for  Prof. Janow's sections of Physics 121 are:

          MPRHJ121002SP20   for section 002
          MPRHJ121004SP20   for section 004
          MPRHJ121010SP20   for Section 010                              
          MPRHJ121012SP20   for Section 012

Be sure to enroll in the correct section.

We will be using a classroom response system called “iClickers”.  Each student must have an iClicker remote unit which can later be sold or possibly used for other courses.  Students must take care of their clickers and bring them to each class.  iClickers are sold at the NJIT book store.
