Important Information for Physics 20700 GH and CH2 students:
Course Objectives: Students are expected to understand the basic physics involved in mechanics (the study
of motion and its causes) and in thermodynamics (the study of heat and work) which is needed for science
and engineering. The emphasis will be on analytical reasoning and problem-solving skills. Note: additional
information on the course objectives for Physics 20700 can be found on the Physics Department web site at
http://mail.sci.ccny.cuny.edu/~physdept/Syllabi/index.htm
in the file labeled 20700 General Syllabus.
Reading Assignment: The text material that will be covered in class each day is listed on the Lecture
schedule. You should read the indicated sections in the textbook before coming to class. Solutions of some
illustrative examples will be presented in lecture. You can try them before coming to class!
Homework: The homework problems are taken from the textbook . In addition, students will be
able to use WebAssign to practice solving homework problems online. WebAssign will evaluate
your homework. You will need the Passcard that comes with your textbook. If you have
purchased a used text, you will be able to purchase access to WebAssign online.
Grades: Grade will be based on the highest score obtained in a) and b):
a)
exams (3 midterms + final)
85%
homework (WebAssign)
5%
lab reports and workshops (7)
10%
b)
exams (3 midterms + final)
lab reports and workshops (7)
90%
10%
Exams: There will be three midterm exams (80 min.) and a final exam (140 min.). No exam grades will be
dropped and no make-ups will be given except in the case of documented illness.
Labs: The Physics Department Lab manual is available on line at
www.sci.ccny.cuny.edu/physics/undergrad. There are seven labs to be completed during the semester.
See lab schedule at
http://www1.ccny.cuny.edu/prospective/science/physics/undergraduate_current.cfm
Lab reports must be submitted at the beginning of the following lab period. Note that the grade of
incomplete (I) will be assigned for Physics 20700 if all seven lab reports have not been submitted by the
required dates.
Workshops: There will be several problem-solving workshops held during the semester during the lab
hours, typically on alternate weeks; see the attached schedule. These periods will be used to help you
develop your skills in solving problems, understanding important concepts, etc. Attendance is required.
Extra help: Students can obtain extra help in this course by meeting with me either during my office hours
in MR324A or at other mutually agreeable times. A tutoring lab will be available in MR418S. You are
encouraged and expected to take advantage of all of these opportunities.
Effort required: Don’t underestimate the amount of effort required for you to succeed in this course. Many
students, in particular those who have not taken a previous course in physics, will need to spend 5-10 hours
per week, every week, studying physics and doing the assigned homework problems, in addition to the time
spent in lecture and lab (7 hours per week).
