Course Material

Course Material: Fundamentals of Physics, Part 3, Seventh Edition, by Halliday, Resnick, and Walker (Wiley).

Physics Laboratory Manual. The lab manual (Physics Laboratory Manual I & II) has to be purchased at the bookstore. The laboratory schedule can be found here.

The laboratory course, PHYS 121A, must be taken concurrently with PHYS 121. The student must register for both the lecture/recitation and the lab course. Withdrawal from either course will cause a simultaneous withdrawal from both courses.

Attendance: Attendance at lectures and recitation classes is mandatory. Any student missing a total of 3 classes, which can be any combination of lecture and recitation, can be dropped from the course by the office of the Dean of Freshman Studies.

Classroom Response System: We will be using a classroom response system called iClicker in sections 007 and 009. Each student will be loaned a clicker, which must be returned at the end of the semester. It is your responsibility to take care of it, and bring it to each lecture. If you lose it, you must pay for a replacement ($26.50). Your grade will be withheld at the end of the semester until you return your clicker.

Grading

Your final grade in Physics 121 will be determined by your performance on the following:

  1. Common Exams: Three common exams will be given during the semester. The schedule is:
    • Common Exam 1 : Friday, October 5, 8:30 9:45 am
    • Common Exam 2 : Friday, November 2, 8:30 9:45 am
    • Common Exam 3 : Wednesday, November 21, 8:30 9:45 am
  2. Final Exam: A comprehensive examination of the entire semester's work will be given at the end of the semester, during December 14 - 20. 2.5 hours long.
  3. Lecture Quizzes: Short quizzes covering the preceding week's work will usually be given during each lecture. The grades count toward your final course grade . There will be no make-up quizzes.
  4. Homework: Homework assignments will be posted on-line at University of Texas Homework System. All the information needed to pick-up your homework every week is listed at Richard Janow 's WWW Page.

The final grades will be based on a composite score that includes each common exam score, the final exam, short quizzes, and the term's homework score. Here are the approximate weights to be used for calculating the composite score:

Here are the approximate weights to be used for calculating the final grade and the final grade scale:

48% for all three common exams (16% each) 80% and more A
32% for the final exam 65% - 79% B
15% for the total homework grade 55% - 64% C
5% for the total lecture quiz grade 50% - 54% D
  49% and less F

Physics Learning Center

The Physics Learning Center, located in 401T, is staffed by faculty and specially trained Teaching Assistants. All Physics students are invited. The time it is open will be announced.

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 Students. 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.

Assignments:

The weekly text, practice problem, and homework assignments are listed in the schedule below . It is almost impossible to succeed in this course without working a lot of problems

  • The weekly text readings are in FOP (Halliday & Resnick). Read each assigned section before the Lecture covering the material in it. We suggest that you download instructor's lecture notes (if available) and bring them to class.
  • There is a set of practice problems posted for 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. The url is: http://web.njit.edu/~janow/Physics 121 Fall 2007/Phys 121Janow Fall 2007.html
  • Each student must download weekly 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 finish and submit it.
  • Homework scores count cumulatively about as much as one common exam toward your final course grade. Students who do not submit the homework are automatically lowering their class average by up to 15%.
  • 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 the work.

Attendance:

Attendance at lectures, recitation classes, and exams is mandatory . Instructors will take attendance regularly. A total of 3 unexcused absences from lecture, recitation, and workshop in any combination is regarded as excessive: the Dean of First Year Students may be notified and a student may be dropped from the course. Students with several excusable absences should contact 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".

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 must be turned off during class meetings and exams.

Help:

If you are having difficulty visit or email your instructor; do not simply hope for a miracle and fall further behind. The Physics Learning Center (401 Tiernan) can provide ongoing help; it is s taffed by faculty and trained Teaching Assistants. The Physics Dept. office on the 4 th floor of Tiernan has more information. Tutors may also be available through the Residence Halls organization.
