What determines your grade:
  • three exams (16% each)
  • laboratory reports (25%)
  • final exam (27%)
  • homework is not graded



What it is:

  • WebCT is a website with password-protected login.
  • For this course it will be used for the limited purposes of allowing you to:
    • view your grades during the semester
    • view homework solutions
    • vote for which HW problems you wish to see reviewed in class

How to use it:

  • Log on using My WebCT
  • The login ID for each new account will be the student's HawkID. If you don't know your HawkID you can find out what it is by calling the Customer Information Desk (384-0800), looking it up in WebISIS ( or calling the ITS Help Desk (384-4357). The initial password for any new WebCT accounts will be the student's University ID number. Students who already have a WebCT v3 account should use their existing user ID. Note that the student's WebCT v2 ID's won't work in WebCT v3.
  • If you have problems using WebCT, call the ITS Help Desk (384-4357).


How many:

  • three one-hour exams
  • a final exam

What they're like:

  • All exams are multiple choice and closed book.
  • The one-hour exams will each have approximately 15 multiple choice questions; some questions will be conceptual (or reasoning) and others will require calculation.
  • Each exam includes one question based on the labs. Example: "In the Coulomb's Law experiment, after adjusting the zero for the torsion-wire balance, you apply a charge to both spheres and you find that the balance turns by 20 degrees; by how many degrees would you expect it to turn if you doubled the separation between the spheres?"
  • A seating chart, showing which seats in the room you may use, will be displayed on the projector screen before the exam begins.

What to bring:

  • Bring a pencil, an eraser, and a calculator. See Policy on calculators.
  • With the exam paper, you will be provided a standard page of formulas.
  • No other notes, materials, or electronic devices are permitted.

The most effective way to study:

  • Before you do homework problems:
    • read the book before the lecture
    • attend the lecture
    • review your lecture notes the same day as the lecture
    • work through example problems
  • Then do the homework
  • After you do the homework, review:
    • your completed homework
    • notes
    • text
    • lab manual

Make up exams:

  • Makeup exams will only be given for verifiable medical reasons or for absence due to official University activities.
  • It is up to you to inform me by email as soon as possible if you will be missing an exam.


  • Efforts are made to prevent and detect cheating on exams.
  • In case of cheating, the instructor will assign a zero for the exam grade and recommend to the Associate Dean that the offender should be placed on academic probation, if it is their first offense.


The role of homework:

  • Homework is the central part of your learning experience, outside the lab.
  • The lecture helps prepare you to do the homework, and the exams test what you learned while doing the homework.
  • Homework is neither collected nor graded; nevertheless, if you wish to perform well in the course, you must do it.


  • You may see the solutions to the homework on WebCT, after the date shown on the schedule.

Help with homework:

  • You may seek help in doing the homework from anybody you wish, including:
    • Your TA, during office hours or after lab
    • TA's in the Tutorial Room
    • Prof. Goree during office hours or by appointment


The role of the lab:

  • Because physics is an experimental science, the laboratory is a critical part of your learning experience in this course.

Who teaches the lab:

  • Lab sessions are conducted by a teaching assistant under the supervision of Prof. Goree and the department's Lab Coordinator.

All students must take the lab:

  • Students who have already taken the course from another instructor, like all other students, must take the lab. This is because Prof. Goree is beginning a new practice of integrating the labs into the course, using more labs, and covering them in the exams.

Before the lab:

  • Read the lab manual
  • Complete the pre-lab report

When your papers are due:

  • Pre-lab reports are due at the beginning of each laboratory period.
  • Worksheets are due at the end of the laboratory period.

If you miss a lab:

  • You may elect to not make-up one lab that you miss; you are required to complete 12 of the 13 labs to pass the course.
  • You may do the make-up lab during the last week of the semester.
  • Making up a lab by attending another section is discouraged. According to departmental policy: only if all three of the following conditions are satisfied will you be allowed to make up a lab by attending another section:

    1. You must get approval, one week in advance, from both your TA and the TA of the lab section you wish to sit in on; and
    2. The lab section you wish to sit in on is not full; and
    3. The lab section you wish to sit in on does not have other
      "visitors" that day.

26 Aug 2002 instructions for E8 Magnetic Fields are missing from your manual. Please print and use this pdf file.
28 Aug 2002 E1 manual and worksheet are in these pdf files; this may be useful if the bookstore is temporarily out of manuals
9 Sep 2002 You may vote, using WebCT, for the HW problems you wish to see solved in the "HW review" lecture preceding the exams. To do this, post a message on the "bulletin board" in WebCT that I've named for this purpose. The bulletin board will be closed at 8 am the day before the "HW review" lecture, and I'll choose the most-frequently requested problems.
11 Sep 2002 The page of equations you will be supplied in Exam 1 can be downloaded and printed from this directory:
The only difference, as compared to the copy you will get in the exam, is that the exam copy will be printed on colored paper. Similar pages for Exams 2, 3, and the Final Exam will appear in this same directory at a later date, a few lectures before the exam.
12 Sep 2002 A sample exam is here. This sample illustrates the types of questions and the format of the exam. The questions in the sample exam happen to represent some of the material in Exam 1. There will be no additional sample exams provided for Exams 2, 3, or the final exam, as they will be similar to Exam 1 except in the material covered, as listed in the schedule.
24 Sep 2002

Exam 1 scores:

  • Your score is now posted on WebCT. Instructions on how to use WebCT appear above. The systems administrator tells me that WebCT will be down from 10 PM this evening to 4 AM tomorrow morning.
  • The maximum possible score was 15, and the highest actual score was 14. The mean score was 8.7, or 58% of the maximum possible. A histogram of grades is here.
  • A table listing the percentile in the class is here. Example: if you received a grade of 6 you can use this table to see that you were in the 20th percentile, meaning that 20% of your classmates scored the same or lower than you. Your percentile standing in an exam is not used in computing your course grade; it merely serves as an indicator of how well you are performing as compared to your classmates.
27 Sep 2002
  • Exam 1 questions and the answer key now appear in a pdf file on WebCT. They will remain there for the remainder of the semester, so that you may view them when studying for the Final Exam. They are combined into a single view-only pdf file.
  • The WebCT systems administrator advises that WebCT is often going down, mainly at night for maintenance to correct a hardware problem; she hopes these outages will be over soon.
8 Oct 2002 The manual for E8: Magnetic Fields and Faraday's Law is missing the instructions. You can find the pdf file here; please print it before your lab.
16 Oct 2002 The page of formulae for Exam 2 is now here:
You may vote for the HW problems you wish to see solved in the lecture before the exam using the bulletin board provided on WebCT.

4 Dec 2002

re. the number of labs that are graded:

If you haven't done 13 labs already, I recommend that you take the makeup lab. Otherwise you will receive a zero for the lab you missed.

Here is how it works:
There are 13 labs, and your lab grade is based on those 13 labs. No grade is dropped in computing your grade for the lab portion of the course. If you've done 12 or fewer labs, you may take the makeup lab next week to replace the zero for a lab you missed. If you've done 12 labs, you may elect to not do a 13th but you will receive a zero for the one you miss. You must do at least 12 labs to pass the course.

There was some false information out there:
One of the TAs informed me today that he previously told his students that he will compute the lab grade using only the 12 highest lab scores, dropping the lowest score if a student does 13 labs. He was mistaken. His plan would have resulted in his students having a grading advantage as compared to students with the other TA. I have asked this TA to remedy this error by emailing his students today, to recommend that they take the makeup lab next week if they have missed a lab. If a student of this TA has missed two labs, we can arrange an additional makeup lab. With this solution, students of one TA are not favored over those of the other.

In a related matter, a student asked me whether he can take the makeup lab even though he has done all 13 labs in order to drop the lowest of his 13 lab grades. The answer is no. The syllabus does not allow for dropping any grades.

5 Dec 2002

All four pages of formulae for the final exam are now here In the Final Exam, you will be provided these four pages, consisting of the same pages you already had for Exams 1, 2, and 3, plus a new page for Chapters 31 and 32.

Homework assignment for Chapter 32:

  • Problems: 2, 4, 34, 35, 36, 37, 50, 52
  • Conceptual Questions: none

Solutions for Homework problems in Chapters 31 and 32 will appear on WebCT one day earlier than the day indicated on the lecture schedule.

6 December 2002

regarding the number of labs that are graded:

The following information replaces the announcement of 4 Dec. that appears above:

I'm reducing the requirements for the lab portion of the course.

Here's the new grading policy for the labs:

Only your best 12 labs will count. If you take more than 12 labs, I will use the best 12. If you take only 12 labs, I will use all 12. (This represents a change from my original plans, which were to use 13 labs in computing your course grade, without dropping any grades.)

One thing that remains unchanged is that you must do a minimum of 12 labs to pass the course.

This change is the result of my discovering that over half the class believed that only 12 labs would be used in computing the course grade. I discovered this problem originally on Wednesday, when I thought it affected only the students of one TA. Today, after lecture, I discovered that it also affected at least half the students for the other TA as well, judging from the attendence for the 13th lab (Geiger Counter).

To solve the problem, my criteria are to treat students equally so that students of one TA are not favored over students of the other TA, and also to minimize disruptions in your plans. This leads me to make the change described above.

Regarding the make-up lab scheduled for the last week of classes, anyone can take this makeup lab. If you have more than 12 lab grades as a result of taking the makeup lab, I will use the best 12 lab grades.

If you have any questions, please feel free to ask me.

23 December 2002

Course grades are now posted on WebCT. Letter grades were assigned as described above.

How your grade was computed:
The column labeled "total weighted" score was computed as 0.75*examtotal% +0.25*lab% where the 0.75 and 0.25 are the weighting factors described above; examtotal% and lab% are ratios of your scores as compared to the maximum possible. I then ranked everyone's total weighted score from top to bottom, and used the College scale described above to assign letter grades. Grades very close to borderline between letter grades were given either a + or a - shading so that the total number of grades with a + shading is the same as the total number of grades with a - shading; most students received a grade that was not shaded.

Histograms appear here:

Note that lab scores had an extremely compressed distribution whereas the exams had a very wide distribution. The two distributions had standard deviations, compared to their mean, of about 1% and 30%, respectively. Consequently, your course grade, which was determined by rank in class, was affected very little by your lab score. Indeed, if one were to swap the best total lab score for the worst,among students who did 12 labs, it would have about the same impact on the course grade as missing just one question on an exam.

Calculators in Exams
  • A simple scientific calculator that does arithmetic, squares and exponents, roots, trig functions, and scientific notation, is best for the exams. It should have a numerical display only.
  • You are not permitted to use a calculator with a display capable of showing graphs, formulas, or text messages.
