To
combat cheating, the provost has stipulated :
While
students are taking their exams
1)
students must
show their ID upon entering the classroom,
2)
there is no cell
phone use,
3)
if a student leaves the room during test time, e.g. Men¡¯s/Ladies¡¯ room,
he/she forfeits finishing the exam.

How to put in numbers at the HW
website
a)
Significant digits and precision
The
computer carries out all calculations to at least six significant digits. Do
not use "significant figures" algorithms to round off your answer. Do
not round off 'intermediate' calculations. Six digits are shown in solutions.
To be scored as correct, an answer must be within 1% of the computer's answer
(except for an answer of zero, which must be exact). You will be informed of
any exceptions to this tolerance.
b)
Scientific/Engineering notation ("times 10 to the power")
Very
large or very small numbers may be input with "scientific notation,"
e.g., +3.56e-10, which is 3.56 times ten to the negative tenth power. However,
468 (or 468.0) is just as good as +4.68e+02 or +4.68E+02.

COURSE OBJECTIVES
Welcome
to Physics 105! Active
learning is the most important objective of this course. Here are some critical outcomes that are
intended:
¡× Improvement of physical
intuition, analytical reasoning and problem-solving skills.
¡× Understanding the basic
principles governing elementary mechanics. Topics include scalar and vector
quantities, rectilinear motion, equilibrium and
¡× 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
¡°NJIT
Physics for Scientists and Engineers Enhanced College Physics¡± by Serway/Faughn/Jewett/Vuille
(From
Serway / Faughn/Vuille, College Physics, 7e, Volume 1-abbreviation B1)
(From
Serway / Jewett, Physics for Scientists and Engineers with Modern Physics, 7e-
abbreviation B2)
Physics
Laboratory Manual (available
in the campus bookstore)
iClicker:
Everyone is required to bring his or her own iClicker for every class, which
can be purchased from NJIT Bookstore.
Each lecture and recitation, there will be quiz problems that should be
answered only with iClickers.
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 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.
HOMEWORK:
Homework
problems will be assigned and graded at the
Homework Service at
Procedure to enroll for the HW service is
posted above (How to enroll for homework.).
GRADING:
Commitment
and preparedness are critical to success in Physics 105.
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 13
Common Exam 2: Friday, March 6
Common Exam 3: Friday, April 17
2) Lecture and iClicker Quizzes (7 %): A
short quiz will be given at the beginning of each Friday lecture. Quiz using
iClicker will be also given during each class.
3) Homework: (8%).
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%)
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
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.
