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.
Homework: The homework problems are taken from the textbook and are posted online. The
homework has to be submitted to : http://www.webassign.net . The homework will be graded (5% of
total score).
Labs: The Physics Department Lab manual and the lab schedule are available online at
http://www.sci.ccny.cuny.edu/physics/undergrad . There are seven labs to be completed during the
semester; see the attached schedule. 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 20800 if all seven lab
reports have not been submitted by the required dates.
Grades: The following components contribute to final score:
exams (3 midterms + final)
90%
lab reports (7)
5%
homework
5%
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.
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, recitation and lab (6 hours per week).
