PHYSICS 105; Fall 2005

§ 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.

§ 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

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

Physics Laboratory Manual (available in the campus bookstore)

Supplemental: 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://physics.njit.edu/classes/physlab 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 111 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, September 30 8:30 – 9:55 am

Common Exam 2: Friday, October 28 8:30 – 9:55 am

Common Exam 3: Friday, November 18 8:30 – 9:55 am

2) Lecture Quizzes: A short lecture quiz will be given during each lecture or recitation period. These quizzes will cover the concepts of the preceding week’s lecture and related homework problems. (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://physics.njit.edu/~phys105

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. (10%)

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

RESOURCES:

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.
