Prof. Ken Ahn's Homepage for Phy105-006, Spring 2007

2. Understanding the basic principles governing elementary mechanics. Topics include scalar and vector quantities, rectilinear motion, equilibrium and Newton's laws of motion, friction, work and energy, impulse, and momentum.

3. Insight to the scientific process: experience with theory surrounding commonly observed phenomena, experimentation, and interpretation pertinent to the fundamental laws of mechanics and conservation laws.

Course material

1. Fundamentals of Physics, Seventh Edition, Volume 1, by Halliday, Resnick and Walker, (John Wiley & Sons, 2005)

2. Physics Laboratory Manual (available in the campus bookstore)

3. Supplemental(not required): Active Physics, Second Edition, by Van Heuvelen and Gautreau (Wiley Custom Svc.)

Course requisites

Laboratory course: The associated laboratory course, Physics 105A, must be taken concurrently unless you have previously taken and passed Physics 105A. The grading for the laboratory is separate from the course/recitation/workshop and the grades are assigned by the laboratory instructors. Please refer to the website http://web.njit.edu/phys_lab for the laboratory schedule and additional information concerning the labs.

Workshop: Physics-A Workshop, Physics 105W, is an integral component of the Phys 105 course/recitation offered in the current semester and it must be taken concurrently. The grade earned in Phys 105W contributes to the final grade for the Phys 105 course. Therefore, it is the student's responsibility to register for the workshop.

YOU MUST BE REGISTERED FOR ALL COMPONENTS OF THE COURSE:

LECTURE/RECITATION (Phys 105)

PHYSICS WORKSHOP (Phys 105W)

LABORATORY COURSE (Phys 105A)

WITHDRAWAL FROM ANY OF THESE WILL CAUSE A SIMULTANEOUS WITHDRAWAL FROM ALL

OTHER Phys 105 COURSES.

Attendance

Attendance at lectures, recitations and workshops is mandatory.

ANY STUDENT MISSING A TOTAL OF 3 CLASSES, WHICH CAN BE ANY COMBINATION OF LECTURE, RECITATION, OR WORKSHOP, WILL BE DROPPED FROM THE COURSE.

Attendance records are periodically reported to the Dean of Freshman Studies throughout the semester. Students with absences need to discuss the reasons for their absences with the Dean.

Grading

Commitment and preparedness are critical to success in Physics 105. Reading assigned material and completing homework assignments will positively affect your performance.

The final grade in Phys 105 will be composed of the following items:

1) Common exams: Three common exams will be given during the semester. The test schedule is given below. The problems in the Common exams will be a combination of multiple-choice and workout type problems. (15% each; 45% total)

Exam schedule:

Common Exam 1 Friday, February 9^th, 8:30 – 9:55 am

Common Exam 2: Friday, March 2nd , 8:30 – 9:55 am

Common Exam 3: Friday, April 13^th, 8:30 – 9:55 am

2) Lecture quizzes: A short lecture quiz will be given during each lecture or recitation period. (7%)

3) Homework: (8%): Homework problems will be assigned at the Homework Service at Texas University. More information is available on the course webpage: http://web.njit.edu/~opyrchaj. No late homework will be accepted.

Homeworks at University of Texas

1. Create your EID at Texas University. Click: Get a UT EID link and fill up the application form (prospective student, invent your SSN). Don't forget to write down your user name and password.

2. Once you have UT EID - login to Texas University and sign as a student to one of the following classes (make sure that you choose the right one) (there is no password to join a class - leave the box empty) (Note: The instructor’s name for the class #41132 will be Prof. Opyrchal, who selects the homework problems for all sections of Physics 105.)

	105 section # at NJIT	Professor	class # at Texas University
1	002	Fayngold M	41130
2	004	Fayngold M	41131
3	006	Ahn K	41132
4	008	Opyrchal J	41133

3. Once you are signed for a class, each time when you login to UTexas you can see the class # on your screen. Click on the class # to pick up homework and/or submit the answers (before a due date).

4) Workshop: The Workshop instructor will evaluate student performance at the Workshops and will report the attendance

and the grades to the course instructor weekly. Workshop assignments are available via http://webct.njit.edu/. (10%)

5) Final exam: A comprehensive test on the semester's work will be given during the Finals week. (30%)

Additional resource: Physics Learning Center

Students are encouraged to meet with their instructor during posted office hours. In addition, the Physics Learning Center, located in 401T, is open to all students and provides tutoring by faculty and experienced students. A schedule is posted outside of 401T.

Honor Code violations/Disruptive behavior

NJIT has a zero-tolerance policy regarding cheating of any kind and student behavior that is disruptive to a learning environment. Any incidents will be immediately reported to the Dean of Freshman Studies. In the cases the Honor Code violations are detected, the punishments range from a minimum of failure in the course plus disciplinary probation up to expulsion from NJIT with notations on students' permanent record. Avoid situations where honorable behavior could be misinterpreted.

No eating or drinking is allowed at the lectures, recitations, workshops, and laboratories.

Cellular phones must be turned off during the class hours.
