                Laboratory - Physics 105A: The laboratory must be taken concurrently with Physics 105 unless you took it

and passed it previously. If you drop Physics 105 you automatically drop the lab - no exceptions. Otherwise,

Physics 105A Lab is a totally separate course from Physics 105. Students receive separate lab grades.

The lab manual (Physics Laboratory Manual I) can be purchased at the bookstore

Physics 105 Course Syllabus - Summer 2006


Lectures / Recitations:


Pre- and Co-requisite Courses:


§          Calculus and vectors will be used.

§         All students must register for a lecture and recitation section, a workshop section, and a section of the laboratory course.  Withdrawal from any of these causes withdrawal from all parts of Physics 106.


Course Materials:


§         Primary text (FOP):  Fundamentals of Physics, Volume 1, Seventh Edition, Halliday, Resnick and Walker (Wiley, New York, 2004).  Physics 106 uses Chapters 10 - 14, and 15.    (Abbreviation: FOP)

§         University of Texas Homework System:  Each student must register by obtaining a guest UT ID and password ( ) and by also signing up for the course using the course number provided by his/her instructor. Students who have a UT ID and password already can reuse it   Homework assignments will be posted on-line.  Students login at, download assignments, solve the problems, and submit answers to the automated grading system.  Specific information will be provided by the instructors and also below. 

§         Web Sites:  Instructors will use the course web site and their own web sites for posting lecture notes, problems, exam results, study materials, etc.  So go there often.


Assignments:  The weekly text, practice problem, and homework assignments are listed in the schedule below.


§         The weekly text readings are in FOP (Halliday & Resnick).  Read each assigned section before the Lecture covering the material in it.  Download instructor’s lecture notes if available and bring them to class.

§         It is almost impossible to succeed in this course without working a lot of problems.  There is a set of “practice problems” posted for you on-line, with solutions.  These will not be graded, but they are a good way to get up to speed before doing the online homework and they are a favorite source of exam questions.

§         Each student must download the homework problem assignments from the University of Texas homework system and submit the solutions online before each assignment is due.  Late work will not be accepted. In general, you will have about a week after homework is assigned to submit it.

§         Homework scores count for 8% of your final grade in the course.  Students who do not turn in the homework are automatically lowering their class average by up to 8%.

§         Homework due dates will be announced by each instructor.  They depend on the class schedule but will generally allow you at least one week-end to complete to complete. 

Short Quizzes:  Short quizzes covering the preceding week’s work will usually be given during each lecture and/or recitation.  The grades count toward your final course grade.  There will be no make-up quizzes.

Examinations:   There will be three Common Exams and a comprehensive Final Exam during the term.   You will be allowed to use formula sheets and calculators. 

The schedule is:

Common QZ 1                       Monday, June 5                   9:00 am – 11:30 am                TIER 106

Common QZ 2                       Monday, June 12                 9:00 am – 11:30 am                TIER 106

Common QZ 3                       Monday, June 19                                 9:00 am – 11:30 am                TIER 106

Final Exam                             Monday, June 26                 9:00 am – 11:30 am                TIER 106

Grading: The final grade will be based on a composite score that includes each common exam, the final exam, the lecture quizzes, homework, and your workshop score.  The weights we expect to use in calculating the composite score are:

§         45%  for all three common exams (15% for each)

§         30%  for the final exam

§         15%  for the total homework grade

§         10%  for the total lecture quiz grade


Grade                     %

A:                            80+

B+:                          75 - 80

B:                            70 - 75

C+:                          65 - 70

C:                            50 - 65

D:                            45 - 50

F:                             below 45


Attendance:   Attendance at lectures, recitation classes, and workshops is mandatory.  A total of 3 unexcused absences from lecture, recitation, and workshop in any combination can result in a student being dropped from the course.    Instructors will take attendance regularly.  The Dean of Students will be notified of excessive absences. Students with several excusable absences should contact the Dean of Freshman Studies.  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 an "F" grade for the course.

Study Groups:  Students find it helpful to form small, informal groups that study work on homework together.  Talking about the concepts, logic, problem-solving methods, etc. with others makes it much easier to learn.  Collaborative learning works and produces better grades.  Socialization is a bonus but should not be the main activity.

Honor Code Violations or Disruptive Behavior:  NJIT policy is zero-tolerance for cheating of any kind and for student behavior that disrupts learning by others.  Incidents will be immediately reported to the Dean of Studies.  The penalties for violations range from a minimum of failure in the course plus disciplinary probation up to expulsion from NJIT with notations on a students' permanent record.  Avoid situations where your own honorable behavior could be misinterpreted.  Students will be required to agree to the NJIT Honor Code on each exam.

Courtesy:  Please do not eat, drink, or create noise that interferes with the work of students or instructors.  Cellular phones, wireless devices, notebook computers, and messaging devices of all kinds are useless during class meetings and exams and must be turned off.
