Physics 221 CE Fall 2008

 

INSTRUCTOR:  Warren Wolfe    Office: L387;    Phone: 773-481-8391;  e-mail: wwolfe@ccc.edu   

                                                 

The required materials for this course are:

 

TEXT:  Physics by Douglas Giancioli, 6th Edition (2004)

CALCULATOR:  You need a scientific calculator with trig functions.

GRAPH PAPER:  One package

 

The course consists of lectures, laboratory experiments, problem assignments, quizzes, and tests.

 

PROBLEM ASSIGNMENTS:  The assigned problems at the end of each chapter will be due on the day announced in class, which is usually the class meeting following the completion of the chapter. You receive one point of credit for each on time assignment. Late homework is not accepted. Homework is the single most important part of the course. Timely completion of the assignments will greatly improve your chances of obtaining a good grade. The quizzes and tests are derived from these problems, so be sure you understand how to do all of them. Get help with those you have trouble with.

 

LABORATORY EXPERIMENTS Do these during the assigned class period. Reports are due two classes later. Each on time lab report is worth two points.

 

QUIZZES will be given frequently, and are always announced during the preceding class. I will try to give twelve quizzes during the semester, each of value ten points. Only your ten highest quizzes will count toward your grade. Each quiz covers one chapter or less.

 

TESTS:  There will be two 100 point tests, each covering one unit. A final exam, also worth 100 points, will cover the entire course with emphasis on the third unit. You may prepare a list of formulas to consult during each test. You may not use a formula sheet during quizzes however.

 

MISSED QUIZZES AND TESTS:  You may not make up missed quizzes, so it is your responsibility to take at least ten. If you must miss a test because of emergency reasons, notify me by the day of the test. Under these conditions you may take a make up test but it likely will be more difficult than the original. Due to equipment and room availability limitations, labs cannot be made up.

 

BONUS PROBLEMS may be assigned occasionally so that you may earn extra credit. These problems are optional.

 

ATTENDANCE: If you miss the first classes you will be dropped. If you miss classes just before midterm, you will be dropped. If you wish to withdraw from the class, it is your responsibility to do so officially by April 14. If you simply quit coming to class, you will receive a grade of F and you will not receive a tuition refund.

ASSISTANCE: I am available during my office hours in room L387 to answer questions and help with your assignments.

q       My office hours are M. T. W Th. 7:50 – 9:20 am. My phone number is 773-481-8391.

q       You may e-mail me at wwolfe@ccc.edu.

q       Tutoring is also available. See the bulletin board for details.

 

ON THE WEB The publishers of the textbook maintain a very helpful web site at http://cw.prenhall.com/bookbind/pubbooks/giancoli/  It contains practice problems, interactive demonstrations, and links to interesting physics web sites. You can even search the entire web for information from this site. You will  find this site useful if you need to take the MCAT test.

 

 

GRADING POLICY:  Your final grade is determined as follows:

a) Calculate your cumulative score by adding the points you received on quizzes, tests, homework, lab reports, and bonus problems.

b) Calculate the base score by adding all the points you could have earned. Do not include bonuses in your base score.

c) Divide your cumulative score by the base score and convert to per cent.

d) Letter grades: A: 92%-100%   B: 82%-92%  C: 65%-81%   D: 50%-64%  F: 0-49%

 

Keep all papers that are returned to you. In the event of a suspected error about your grade you will need them to document your score. Also, they provide a helpful review when preparing for tests. I will keep a record of all students’ performance on the bulletin board. Be sure to check it frequently and report any discrepancies to me. An interactive copy of the grade sheet is posted on the class website. (You need Internet Explorer to access the grade sheet.)
