Course Objectives:
Physics 220 is designed to introduce you to the core concepts of electricity and magnetism and to help you develop sufficientTexts, Tools, and Resources:
1.
Course Packet: includes walk-in lab descriptions, What does it mean to Integrate? by Ross Spencer, Study Guide for General Physics2.
Text: Physics for Science and Engineers, by Serway and Beichner, 5th edition. This text may be purchased as one large book (which is3.
Course website: This site contains links to course and grade administration features, updated class schedules, and announcements that4. The
Tutorial lab is located in N304/N362 ESC. Courteous Teaching Assistants will be available there at posted hours Monday through
5. Peers.
You are encouraged to study in groups. If you feel that you are not able
to participate in or lead discussion, you may need a new
study group.
6.
Calculator: Except for Exam 1 (math review), you will be able to use calculators for exams and homework problems. Any scientific7.
CIDs: All quiz, homework, lab, and exam grades are recorded according to a class identification (CID) number. Your number has been8.
Electronic Quiz Transmitters: We will NOT use quiz transmitters this semester.9.
Exam solutions will be distributed in class after each exam. If you have questions about these solutions, you may visit the instructor during10.
Mechanical Universe videos. These media resources, some of which are used in class, contain illustrations and demonstrations that willPrerequisites:
1.
Math 112 is absolutely required. Math 113 is recommended. If you feel
that you need to review Calculus, check out Quick Calculus
(Kleppner, QA 303
.K673 1985) at the reserve desk.
2. Physics 121, or CE 103 completed and CE 204 concurrent.
3.
Basic math skills are reviewed in Appendix B of your text. Vectors were
covered in Physics 121, and will be briefly reviewed in class.
Aspects of Math 214
and 343 are used in the course, though these classes are not required.
Expectations:
1.
Physics 220 has a well-deserved reputation as one of the most difficult
undergraduate courses taught on campus. Plan on spending 20-25
hours of study time
each week. You may require more time if your physical intuition is
not well developed. A good indicator may be how
well you do on
‘story problems’, as they are the bulk of your homework and tests. A few
students will require less time. If you do not feel
that you have enough
time to dedicate to this class right now, consider taking it another semester.
2.
Keep up. Reading, Study Guide, and homework assignments come due
each class period. The concepts in Physics 220 are cumulative,
even more so than in
other science classes. If you fall behind you will be in trouble.
Should this happen to you, then talk with the instructor
immediately to get
help.
Quizzes:
1. In-class quizzes will be given, unannounced, at random times throughout the term. In addition to physics questions, you may be asked to
2.
Study Guide (SG) units walk you step by step through representative homework
and exam problems on topics covered in the most recent
lecture. Work
through the Study Guide frame by frame. Cover up the solutions as you
work the problems, and correct yourself as you go.
Your SG work does
not have to be neat--rough notes are acceptable as your time is valuable.
While you do not submit SG answers online,
you will receive
points for Study Guide work reported on quizzes..
3.
Reading assignments include sections from your text (Serway and Beichner, Physics for Scientists and Engineers, 5th Ed.) and from your4. Quiz questions will include topics from the current reading assignment and from past lectures.
5. Quiz points will be added to homework points in determining your grade.
Walk-in Labs:
1. In the course packet you will find walk-in lab work sheets for twelve short laboratory experiments. The labs are very important and include
2. The Walk-in Lab (S415 ESC) will be open
any time the building is open. Labs will be taken down and set up between
7:00 am and 12:00
noon on the days
indicated for set-up and take-down. Labs may not be available during this
time.
3.
You will normally do your experiments without assistance, but, if you
encounter difficulties with any particular lab, you may choose to perform
your experiments on
either Thursday or Friday between 12:00 noon and 5:00 pm when TAs will be
present in to the laboratory.
4. The lab reports are due in the 220 homework/lab submission bins
located across from N375 ESC by 9:00 pm on Friday night on the date
indicated in the
class schedule. Lab reports are to be submitted in the bin corresponding
to the first digit of your CID#. Work without a
CID# will not be graded.
After grading, your lab reports will be returned to you in the adjacent
distribution bins according to the first two
digits of your CID#.
5. During Spring Term, two walk-in lab assignments are to be completed
on many weeks and three assignments are due on the final Friday of
the term.
Homework:
1. CID#: Homework assignments
will be submitted on-line via links on the course website, which requires your
CID# and the last four digits of
your BYU ID for access.
The homework problems are found in your course packet, and require input data
that is unique to your CID#
(also accessed via the
course website).
2. Multiple-choice problems are worth 2 points each. Each part of
a multi-part problem is worth 2 points and is scored independently. You
only get one attempt at
a multiple-choice problem.
3.
Numeric
problems are worth 2 points each. Each part of a multi-part problem is worth
2 points and is scored independently.
After an initially
incorrect response,
a numeric problem can still be resubmitted two more times without penalty.
When you submit an incorrect answer, the
on-line homework
system will give you the correct answer along with new input data to be used
in your next attempt. Thus the correct
answer will be different
for each attempt. If you have only answered some of the parts correctly, only
the incorrect responses need to be
resubmitted. Once
you get a part correct, the system will protect you from yourself by ignoring
any subsequent changes that you make to that
part.
4. Numeric response ranges: Each numeric problem description
includes (1) upper and lower bounds for the response, the numeric precision
required, and the
physical units expected. If your answer falls outside the range
indicated, you have likely made a mistake. Because
computerized
grading systems can be very exacting, we have provided this information to you
to make your online homework experience
more pleasant.
When scientific notation is required, enter 8.51×10-8
as
8.51e-8,
and 2.6×107
as
2.6e7
(no spaces).
Check
twice–press
'Enter' once.
Do not appeal for
points lost due to
miscalculations, round-off errors, typos, etc.
5. Written homework problems: Some homework assignments will
require written work that must be submitted to the Physics 220
homework/lab submission bins
located across from N375 ESC. Place your work in the bin corresponding
to the first digit of your CID#.
Work missing a CID# will not be
graded. After grading, your written work will be returned to you in the
adjacent distribution bins according
to the first two digits of your
CID#. Like the online homework problems, these will be due by 7:45 am
(just before class) on the dates
indicated in the class schedule.
Late written homework problems will also be accepted late for half credit, but
cannot be resubmitted.
6.
Homework due dates: Both online and written homework submissions are due
at 7:45 am (just before class) on the dates indicated in the
class schedule, at
which time solutions will be posted in the display cases across from N361 ESC
for one week. You may submit homework
problems at any
time during the semester up until midnight on the last day of class (June 13).
However, any points earned after the
corresponding due
dates are considered late and only receive half credit.
7.
Notes: You are STRONGLY encouraged to keep neatly written copies of all
your homework problems. If you don’t, it will be very difficult
for you to figure
out what mistakes you have made, or to study your homework in preparation for
exams.
8.
Do not share homework responses with other students before the solutions are
posted unless you worked together to obtain those responses.
Group study is
encouraged. Helping others to learn material that you have mastered is
encouraged. Giving out answers, on the other hand, is
not acceptable.
9.
You may miss or "bomb" three homework assignments at no cost to you in points.
At the end of the term your three homework scores which
have the largest
deficits (difference between perfect and your score) will be made perfect.
Midterm Exams:
1. Midterm exams will be given in the testing center on the dates indicated in the class schedule. Exams will be available from noon on the
2. Midterm exams will usually contain about twenty-five machine-graded
multiple-choice questions and five written-response (similar to
homework) and/or
essay questions which will be hand-graded. Two hours is the average time
spent per exam. You may use your copy of
Formulas and Chapter Summaries
(found in the course packet),
a scientific calculator (no PDA), and scratch paper (which must be
submitted
with your exam). Students whose
native language is not English may use a foreign
language dictionary. It is common for several
of the exam problems to
come right out of the course packet. Each exam will include problems
requiring calculus.
3. Midterm exams will be returned to you in the distribution boxes to
the right of the 220 homework submission bins. You must put your CID#
on all exams or lose
points.
4. Do not discuss the problems or answers to a current exam with other students until after the exam solutions have been distributed in class.
Final Exam:
1. The final consists of roughly 40 multiple-choice questions similar to those on the midterms.
2. The final exam is comprehensive, though Chapters 16 and 34 will be emphasized (25% of the questions).
3. The final exam will be available in the Testing Center during the
normal final exam period. There is no time limit, except closing time. The
final
exam is confidential and will not be returned to you, though you may
review your exam your instructor.
4. As with the midterms, prepare by working through sample exam problems in the course packet.
Grades and Grading:
1. Many students want to see how they are doing and more importantly to know that we have recorded their scores properly. Scores can be
2. If you feel that your work was unfairly or incorrectly graded, or if
you notice other problems with your grades, you may either write a note
and place it in the
`220 APPEALS' box (located just below the homework bins). If the appeals
grader's adjustment or written reply is
unsatisfactory, you
may further appeal to the instructor. Any appeal should be started
within one week after you receive the graded work or
after a prior
appeal is returned.
3. Final grades are determined according to the following breakdown:
GRADING WEIGHTS
| Item Category | Number | Weight per Item | Total Weight |
| Homework | 35 | ~ 0.8% | 32% |
| Quizzes* | ? | Variable, 0.2%-0.6% | |
| Walk-In Labs | 12 | 0.67% | 8% |
| Midterm Exams | 4 | 10% | 40% |
| Final Examination | 1 | 20% | 20% |
*The scores for individual quizzes are variable. Typically the point value of a quiz will be about one-third to one-half that of a homework assignment. LETTER-GRADE SCALE
| GUARANTEED GRADE SCALE | |
| If your numerical score (%) is at least | then you are guaranteed a letter grade of at least |
| 92 | A |
| 88 | A- |
| 84 | B+ |
| 80 | B |
| 76 | B- |
| 72 | C+ |
| 68 | C |
| 64 | C- |
| 60 | D+ |
| 56 | D |
| 52 | D- |
| 0 | E |
The grades are normally assigned on the basis of a class curve with grades of A and A- going to the top ~15 to 20 per cent of students, grades of B+, B or B- going to the next -25 to 30 per cent, etc. The actual grade breaks are made where there are naturally occurring gaps in the score distribution so the percentages in each group are somewhat variable. After your grade is determined from the class curve, your grade will also be determined from the above guaranteed grade scale. You will be given the higher of the two grades. (Thus, in the unlikely event that everyone in the class earns more than 92 per cent of the possible points, everyone will be given an A grade regardless of position on the class curve.)
Occasionally, by special request, we use weights other than those above for students with special needs or unusual preparation. Such arrangements must be made with your instructor at the beginning of the term. Be sure to get a written agreement.
Miscellaneous Items:
BYU Standards: Each of you has signed a
pledge to maintain BYU standards including those of honesty, respectful treatment of
others,
and modesty and dignity in dress and grooming. Your instructor is also committed
to those standards and expects, as a matter of honor, that
the conduct of all class
members will be in conformity with those standards.
Messages: We will put announcements and instructions in the message section of the course web page from time to time. We will assume that
Students with Disabilities: BYU is committed to providing reasonable accommodation to qualified persons with disabilities. If you have any
Sexual Harassment: BYU's policy
against sexual harassment extends not only to employees of the university but to students
as well. If you
encounter sexual harassment or gender-based discrimination, please
