Pre- and Co-requisite Courses:

Prerequisite: Phys 105 or the equivalent. Co-requisite: Math 104, 111 or an equivalent calculus course. Vector operations including cross product, differential calculus, and some elements of integral calculus will be used.

All students must register for Physics 106 and the laboratory course Physics 106A. Withdrawal from any of these causes withdrawal from both parts of Physics 106.
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”, 7th Edition, authors
Serway and Jewett , (Thomson 2008). We use chapters 10 - 15. There are custom NJIT versions of this book titled “NJIT Physics 105/106” and “NJIT Physics 111” sold in the NJIT bookstore, as well as hardbound and paperback versions. Any 7th 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 sign up for this course itself using the 5 digit 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 take care of their clickers and bring them to each class. The iClicker quizzes must be answered with iClickers only.

Email is routinely used for announcements and to distribute material: be sure the instructor has your NJIT or another working email address.
Exams :

There will be two Common Exams and a comprehensive Final Exam during the term. The exam schedule is:
Common Exam 1: Thursday, June 3, 9 – 11 am
Common Exam 2: Tuesday, June 15, 9 – 11 am
Comprehensive Final Exam: Monday, June 28, 9 to noon
There will be no makeup exams.
Grading:
Final grades will be based on a composite score for the term’s work that includes two common exams, the final exam, homework score, iClicker quizzes, and class participation. The approximate weights we expect to use in calculating the composite score are:

40 % for two common exams (20% for each)



40 % for the final exam
10 % for the total homework grade
10 % for iClicker quiz + 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.
The following grade scale will be used to assign percentage of points earned to a letter grade for the course: Note grades less than 50% are failing.
A 80+
B+ 75-79
B 70-74
C+ 65-69
C 55-64
D 50-54
F < 50
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 work will not be accepted.
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 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: If you are having academic or other difficulty, visit or email your instructor: do not simply hope for a “miracle” and fall further behind. Tutoring may be available through NJIT. 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 10611 )
Wait a couple of days until the instructor approves your enrollment.
Doing HW
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
(For some browsers, a bar appears at the top saying “To help protect security, ….”. Then, right click the bar and “download file”.)
5. Save or open your homework (pdf file format).
6. You get your homework!
7. You can print, or retrieve the same HW later. Check out the due date.
8. On the right side of this web page, you can submit your answers. (For some browsers, you may need to scroll to the right to see this.)
9. You can log out and submit your answers later till the due date.
Check “Help” tab for useful info on the HW system.
