Covers everything
learned in this semester
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.

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)

in the campus bookstore)
iClicker:
The course requires everyone in Section 011 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
Procedures to enroll for the HW service
will be explained later.
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, October 3th
Common Exam 2: Friday, October 31st
Common Exam 3: Friday, November 21st
2) Lecture and iClicker Quizzes (7 %): A
short quiz will be given at the beginning of each Tuesday lecture. Quiz using
iClicker will be also given during classes on Tuesdays and Fridays.
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.

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.
