This will be the last semester in which Phys 106 is offered at NJIT. If you don’t pass with C or better
grade, you would have to take Phys 111 in future. – One more reason to pass Phys 106 this semester.
Pre- and Co-requisite Courses:
•
Prerequisite: Phys 105 and Math 108, 109, or 110 with grade “C” or better. Co-requisite: Math
111 or an equivalent calculus course. Physics 106 will use vector operations including cross product,
some differential calculus, and some elements of integral calculus.
ƒ All students must register for Physics 106 and a section of the laboratory course Physics 106A. If
you drop either Physics 106 or 106A, you automatically drop both courses.
Laboratory - Physics 106A:
The laboratory must be taken along with Physics 106 unless you took it and passed it previously. If you
drop Physics 106 you automatically drop the lab - no exceptions. The Lab is otherwise a totally
separate course from Physics 106 but with related experiments. Students receive separate lab grades and
the lab instructors set the requirements and policy. The lab manual can be purchased at the bookstore; you
can check the lab schedule at http://physics.njit.edu/students/lab-handbook.php
Course Materials:
•
Primary text (abbreviation SJ): “Physics for Scientists and Engineers”, 8th Edition, authors
Serway and Jewett, (Thomson 2010). We use chapters 10 - 15. There are custom NJIT versions of this
book titled “NJIT Physics 105/106” that is sold in the NJIT bookstore, as well as hardbound and
paperback versions. Any 8th edition book with “Scientists and Engineers” in its title that includes the
chapters listed is OK. You do not need to use the publisher’s on-line study and homework systems,
although it might be useful.
•
University of Texas “Quest” Homework System. Students can re-use existing UT EIDs and
passwords or get new ones. Students must also “enroll” in this course using the 5 digit UT course number
provided below. Homework assignments will be posted on-line in Quest. Students login, download
assignments, solve the problems, and submit their answers to the automated grading system. More
specific information is below and will also be provided by the instructor.
•
Classroom Response System: We will be using a system called “iClickers”. Each student must
have an iClicker (about $40 new at the NJIT bookstore, less if bought used) which can be sold back or
used for other courses like Physics 121. Students must bring them to each class. The iClicker quizzes
must be answered with iClickers only.
•
Email is routinely used for announcements and to distribute material: Emails will be sent to your
NJIT email address. If you prefer to receive emails at non-NJIT email address, please email the instructor
from that address with a requst.
Exams:
There will be three Common Exams and a comprehensive Final Exam that tests for knowledge equivalent
to that expected of Physics 111 students. The exam schedule is:

Common Exam 1: Monday, September 26
Common Exam 2: Monday, October 31
Common Exam 3: Monday, November 21
Comprehensive Final Exam: during December 14 to 20
4:00 – 5:45 pm
4:00 – 5:45 pm
4:00 – 5:45 pm
2.5 hours
Grading:
Final grades will be based on a composite score for the term’s work that includes common exams, the
final exam, homework score, iClicker quizzes, and class participation. The approximate weights we plan
to use in calculating the composite score are:
ƒ 45% for all three common exams (15% for each)
ƒ 30% for the final exam
ƒ 5% for total homework grade
ƒ 20% for iClicker quiz + Written Lecture Quiz + class participation
Extra credit may be given for active class participation, etc. Negative credit may be applied for lateness,
creating noise, or otherwise interfering with class work.
C or better grade is required to take further physics courses. If you get D in Physics 106, you
cannot take the next level physics course and you would have to take Phys 111, since Phys 106 will
not be offered any longer.
Reading Assignments: The text readings are listed below. You should read the assigned sections of the
text (Serway & Jewett) before the lecture covering that material.
Homework: It is almost impossible to succeed in this course without working a lot of problems: do the
homework. Each student must download the weekly homework assignments from the University of Texas
homework system, work the problems, and submit the solutions online before each assignment is due.
Late homework will not be accepted.
“Practice Problem” sets with solutions (distinct from the homework problems): These practice
problems are posted for you on-line. They will not be graded but are a good way to get up to speed before
doing the online homework. The url is:
http://web.njit.edu/~janow/Physics 106 Spring 2011/Phys 106Janow Spring 2011.html.
Attendance: Attendance will be taken at all classes and exams. More than 3 unexcused absences from
lecture is excessive and may result in a notification to the Dean. If you have excusable absences contact
your instructor or the Dean of First year Students. If you withdraw from the course, do it officially
through the Registrar; do not simply stop attending and taking exams. Students who withdraw unofficially
force the instructor to assign a course grade of "F".
Honor Code Violations or Disruptive Behavior: NJIT has a zero-tolerance policy for cheating of any
kind and for student behavior that disrupts learning by others. Incidents will be immediately reported to
the Dean of Students. The penalties for violations range from a minimum of failure in the course with
disciplinary probation and grade “FX” up to expulsion from NJIT. Avoid situations where your own
behavior could be misinterpreted, even if it is honorable. Students are required to agree to the NJIT Honor
Code on each exam. Turn off all cellular phones, wireless devices, computers, and messaging devices of
all kinds during exams. Please do not create noise in class that interferes with the work of students or
instructors.
Study Groups: Many students find it helpful to form small groups that study & work on homework
together. Talking about the concepts, logic, problem-solving methods, etc. with others makes it much
easier to learn.
Help:
Students are encouraged to meet with their instructor by arranging office visit. In addition, the
Center for Academic and Professional Enrichment (CAPE) [http://www.njit.edu/cape/] located in
200 Kupfrian Hall, is open to all students and provides tutoring by experienced students. The
Physics Learning Center (401 Tiernan) can also provide ongoing help; it is staffed by faculty and teaching
assistants. The Physics Dept. office on the 4th floor of Tiernan has more specific schedule information.
Specific information for the UT QUEST homework system:
Homework problems will be assigned and graded at the Homework Service at Texas University.
Getting UT EID
If you already have a University of Texas (UT) Guest login ID and password, you can continue to use it.
If not, you need to get UT EID (not UCID) by following instruction at
http://cns.utexas.edu/quest/support/student/. Fill out the following for your own future reference, and keep
it someplace where you can find it:
• Your Login ID on the UT system (generated when you register with UT; case sensitive!):
______________
• Your own password (selected upon registration with UT; confidential!): ______________
Signing up for the course
Follow “Off Campus Student Enrollment” (Unique # for the course is 10699)
Wait a couple of days until the instructor approves your enrollment.

After the instructor approves your enrollment, you can download, do the HW, and submit your answers:
1. Visit https://quest.cns.utexas.edu/student
2. Click “Get Started” and log in with your UT EID.
3. Under “My Course Tab”, click “Phys 106 ”
4. Click the assignment
