General Information

Physics 54L is taught using lectures, recitation sessions, labs and the internet.

The lectures and recitations are conducted by Dr. Evans. There is a morning session for the whole class in Rm. 128, Monday through Friday, from 11:00 until 12:15. These sessions include lectures and some recitations.


The whole class also has a regular two hour afternoon recitation twice a week, on Tuesdays and Thursdays from 1:15 to 3:15, in Rm. 154.


There are labs once or twice a week in Rm. 141, in the afternoons. These are conducted by the assistants. The section schedule is as shown below.

Labs

1

Monday 1:15-3:15
Wednesday 3:30-5:30

Monday 3:30-5:30
Wednesday 1:15-3:15

Students must have a copy of Physics for Scientists & Engineers (Vol. II) , by Giancoli, 4th ed., Prentice Hall. This book is referred to as G.

Course Structure

The web site contains complete notes on the material covered in the course, in Adobe pdf format. Links to them by subject are at the top of this page. These notes are the primary source of material coverage in the course. The book (G) provides alternate presentations, applications, worked examples, and sets of questions and problems used in recitations and for homework. There are topics covered in the notes but not covered (or not adequately) in G; these topics are part of the course. Topics (mostly special applications) covered in G but not mentioned in the notes are not part of the course.

Lectures
summarize the main topics, but are not expository lectures presenting in detail all the material of the course. They are organized on the assumption that the students have already studied the material in the notes and G, so the sessions are devoted largely to illustration and reinforcement, using demonstrations and sample problems.

Recitation sessions
are devoted mainly to discussion of assigned problems and questions listed in the weekly schedules at the top of this page. It is assumed that the student has attempted to answer the questions and solve the problems before the recitation session in which they will be addressed.
 
Each recitation class is divided into small working groups of three or four students. At the beginning of the session members of each group discuss the questions and problems among themselves, to arrive at their group's solutions. During this time, the instructor and assistant are available for coaching and suggestions. At the end of the working time, the instructor calls on groups in sequence to present to the rest of the class their solution to a specific problem or question. One student from each group makes the presentation for that group. The instructor provides suggestions, correction or amplification of the student's presentation as appropriate. No grade is recorded on these presentations.
 
At the end of each afternoon recitation session there is a brief (about 20 minutes) graded quiz on the material just discussed. There are no quizzes in the morning recitation sessions.

Lab exercises are carried out once or twice per week. A total of six labs will be done.

Exams and Grades

There are three in-class exams, given during the morning period, with a maximum of 100 points each. The comprehensive final exam has a maximum of 200 points. This 500 points constitutes the total exam score for the course.

Calculators are not to be used for in-class exams or the final exam, but may be used for quizzes. The formula sheet linked at the top of this page may be used on quizzes and exams.

If a student misses an in-class exam for an excused reason, the score on that exam is replaced by the percentage score on the final exam.

A few homework problems (denoted in the assignments by *) are to be written out and handed in at the beginning of the corresponding recitation session. These will be checked for completeness, but not graded. A score will be assigned, based on the number turned in. Problems not turned in will count against this score. Discussion among students in preparing the homework assignments is encouraged, but direct copying  of any graded material is a violation of the Honor Code.
 
The recitation quizzes will cover the material discussed in that recitation session. They are intended to reinforce what was just learned and to give practice in the kinds of questions that might be on the exams. Absences from quizzes are recorded as zeroes.

At the end of the course, the lowest homework grade and lowest two quiz grades will be dropped for each student. This is done mainly so that an occasional absence will cause no penalty.

For a student whose final exam percent score is higher than the average score on the in-class exams, the final exam is given extra weight so that the total exam score is calculated as 50% in-class exams and 50% final exam.  

The various graded material contributes to the final score as follows:
      
•    Exams: 75%
•    Quizzes: 10%
•    Labs: 10%
•    Homework: 5%

Exam and quiz keys, as well as sample exams from previous versions of this course, are posted on the course web site. A link to the relevant page is at the top of this page.

Answers (from the published instructor's manual) for the even-numbered assigned problems from G are reached by a link at the top of this page.
