PHYSICS 6C
UCSB
SPRING 2005

Image: The spiral galaxy NGC 6118, about 80 million light-years from Earth. The light from this galaxy, an electromagnetic wave, is the result of nuclear reactions taking place within the galaxy's stars. The spectrum of this light, which we detect using a telescope, reveals the composition of the stars in NGC 6118. These physics concepts are just part of the subject matter of Physics 6C.

 REQUIRED TEXTBOOK:
PHYSICS, Second Edition, by James S. Walker is the required textbook. This is the same text as used in Physics 6A and 6B.

You are required to do the assigned reading before attending lecture.

The companion web site (http://wps.prenhall.com/esm_walker_physics_2) has a number of features designed to help you learn physics. Visit this site often!

Return to top of page

 PREREQUISITES: You must have completed each of Physics 6A, Physics 6B, and Math 3A (or 34A) with a passing grade (C- or higher).

Return to top of page

 COURSE OBJECTIVES: At the end of the class, you should be able to set up and solve problems in the areas covered by the class. Solving those problems requires both a basic knowledge of the concepts and physical laws involved, and a skill in applying those concepts through drawing diagrams, strategizing, writing and solving equations, and understanding what the results mean. You should not have to memorize lots of equations or pages of information, but you should know where to find them and how to use them.

 WHERE TO GET HELP:

Your instructors are available to answer your questions about any aspect of Physics 6C (or anything else concerning physics) during their office hours, or at other times by appointment. Please come by!

Physics Study Center (PSC): Located in Room 3314, Broida Hall, the PSC is where all physics TAs hold their office hours. The PSC is open Monday through Friday, 8:00 a.m. to 4:30 p.m., and TAs are on duty at most times. This is where your TA will hold his office hours. (Click here for a complete schedule of all TA office hours in the PSC.)

Note that all the TAs you'll find in the PSC are able to provide assistance with Physics 6C. This is a unique and extremely helpful component of our Physics Department. Make full use of it!

Campus Learning Center (CLAS): CLAS provides tutorial assistance for all courses, including special tutorial sections for Physics 6C. CLAS is in Building 477 in the Student Services Complex area (telephone 893-3269). For more information, click here to visit the CLAS web site, and click here to see a map that shows where CLAS is located.

Dealing with Student Stress: Stress is a natural part of student life. Santa Barbara physician Jay Winner, MD has created an effective program for dealing with stress of all kinds. For details, click here.

 WHERE NOT TO GET HELP:

Academic dishonesty is not acceptable in Physics 6C or any other course at UCSB. If you copy from another student's exam, you will receive an F in the course. In addition, a Faculty Report Form for Academic Misconduct will be sent to the Office of the Dean of Students, and your case will be referred to the Student-Faculty Committee on Student Conduct. It is not uncommon for a first-time offender to be suspended from the University for one quarter for committing one act of cheating. A second offense commonly leads to permanent suspension from the University.

This is not an idle threat, but a description of what has happened on previous occasions when cheating occurred. Remember that cheating hurts everybody, and you should not hesitate to inform your instructor or teaching assistant if you witness an act of cheating. Academic dishonesty will not be tolerated.

 REQUIRED PHYSICS 6C DISCUSSION SECTIONS: Every other week you will attend a discussion section. In the discussion sections you will form into small groups to solve physics problems that are challenging, informative, and entertaining. You will also have a chance to present your work at the blackboard!

IMPORTANT: Discussion sections are REQUIRED for all students enrolled in Physics 6C! Your attendance at and participation in the discussion sections is worth 5% of your grade in Physics 6C.
IMPORTANT: Bring the following with you to each discussion section:
  • your textbook;
  • a calculator with fresh batteries;
  • a pen or pencil;
  • scratch paper.
  • If you are enrolled in Physics 6C but not Physics 6CL, you are still required to attend discussion section. You may go to any discussion section you want starting in either the first or second week of classes (see below under "Which week do I go to lab? Which week do I go to discussion section?") Whatever section you pick, however, you are required to go to that same section every other week for the remainder of the quarter.
  • If you are enrolled in Physics 6CL but not Physics 6C, you are required to go to the labs but you are NOT required to go to the discussion sections.

Return to top of page

 PHYSICS 6CL LABS: Physics 6CL is a separate 1-unit laboratory class to be taken concurrently with Physics 6C. You must register for this class separately from Physics 6C.

IMPORTANT: Before coming to your first lab section, you must purchase a Physics 6C Lab Manual from the UCSB Bookstore. In addition, before coming to your first lab section you must read carefully the description of the first experiment ("Lab 9: Electronics and Circuits – Nerve Cell Activities"). See below under "Which week do I go to lab? Which week do I go to discussion section?" to find out whether your first lab section is during the first or second week of classes.


IMPORTANT: Bring the following with you to each lab:
  • your Physics 6CL lab manual;
  • a calculator with fresh batteries;
  • a pen or pencil;
  • a pad of quadrille-ruled 8 1/2" x 11" paper (ruled in a grid with 4 or 5 squares per inch), available at the UCSB Bookstore.
Other things to remember for each lab:
  • Please don't wear open-toed shoes or sandals to lab. Sometimes a piece of lab equipment gets dropped, and an exposed toe is a bad place for it to land.
  • In the lab, please store backpacks under the tables (not in the aisles) and place skateboards against the wall.

 WHICH WEEK DO I GO TO LAB?
WHICH WEEK DO I GO TO DISCUSSION SECTION?

If you are enrolled in Physics 6CL, look in the Schedule of Classes (available online at http://www.registrar.ucsb.edu/soc.htm) for the location of your 6CL class. It will list two rooms, the first of which is either "BRDA 2324A" or "BRDA 2324B."
  • If it says "BRDA 2324A," you are in an "A" section. You have lab in Broida 2324 during the first week of classes. You have discussion section during the second week in the second room listed.
  • If it says "BRDA 2324B," you are in a "B" section. You have discussion section during the first week of classes in the second room listed. You have lab in Broida 2324 during the second week of classes.
The table below lists this explicitly.

 HOMEWORK ASSIGNMENTS AND WEBASSIGN: Homework will be assigned each week. Homework problems are from the textbook, and must be solved and graded on the WebAssign website (http://webassign.net/login.html). These usually require numerical answers, with different constants for each student. Answers must be given to 3 significant figures. You will need a calculator to work them. Homework assignments will be posted on WebAssign by each Monday, to be turned in before midnight the following Monday.

NOTE: If you have any problems logging in to WebAssign, contact the Physics 6C head TA, Eric Luckwald, at phys6chta(at)physics.ucsb.edu. (Do not contact your instructor.)

WebAssign directions: To use WebAssign, go to http://webassign.net/login.html and enter the following information:
  • Username: Your username is your 7-digit perm number (no spaces or dashes). (NOTE: This is different than in Physics 6A or 6B, in which you used your U-mail username.)
  • Institution code: ucsb (Note: you must use lowercase)
  • Password: Your password has been set to your perm number. You should change it for security, but don't forget the new password that you choose! If you have any password problems, e-mail Eric Luckwald [phys6chta(at)physics.ucsb.edu] and ask him to change the password back to your perm number.
Then click on the Log In button.

NOTE: You must also register with WebAssign and pay the quarterly user fee (about $6) by no later than 2 weeks after classes begin. You can do this by either (a) making a secure credit card purchase on the WebAssign site or (b) purchasing a WebAssign access card at the UCSB Bookstore. If you fail to register with WebAssign by the deadline you will receive no credit for missed assignments. If you decide not to register, please let your instructor know since otherwise you may not receive a grade for the class.

 IN-CLASS EXAMINATIONS: The dates of the in-class exams are as follows:

  • First midterm exam: Thursday, April 21, 2005 in Room 1610, Broida Hall during your normal lecture period. You MUST take the exam for the lecture section in which you are enrolled.
  • Second midterm exam: Thursday, May 19, 2005 in Room 1610, Broida Hall during your normal lecture period. You MUST take the exam for the lecture section in which you are enrolled.
  • Final exam: Saturday, June 4, 2005 from 7:30 to 10:30 p.m. in Campbell Hall. Both lecture sections will take the same exam.
IMPORTANT: You must bring a photo ID to each exam.

 GRADING SCHEME: The various parts of the course are weighted as follows:
  • WebAssign homework: worth 15% of the total points for the course
  • Participation in discussion sections: worth 5% of the total points for the course
  • First midterm exam: worth 20% of the total points for the course
  • Second midterm exam: worth 20% of the total points for the course
  • Final exam: worth 40% of the total points for the course
Note: If you turn in all 9 graded homework assignments, your grade will be calculated with homework weighted as 25% of the grade (rather than 15%), if this gives you a better overall grade. In this case the various parts of the course will be weighted as follows:
  • WebAssign homework: worth 25% of the total points for the course
  • Participation in discussion sections: worth 4.41% of the total points for the course
  • First midterm exam: worth 17.65% of the total points for the course
  • Second midterm exam: worth 17.65% of the total points for the course
  • Final exam: worth 35.29% of the total points for the course


THIS COURSE IS NOT GRADED ON THE CURVE. Your grade in Physics 6C will depend on what percentage of the total possible points you receive (from WebAssign homework, discussion section participation, and in-class exams), using the following scheme:

Course grade Percentage of possible points needed for this grade
A+ 90%
A 80%
A- 75%
B+ 70%
B 65%
B- 60%
C+ 55%
C 50%
C- 45%
D 40%
F less than 40%

There will be no make-up exams. Consultation with your instructor may excuse you from a midterm, for serious illness, for the funeral of a parent or sibling, or for other emergencies. If you miss a midterm with a valid excuse your grade will be based on the remaining exams and homework. If you miss the final with a valid excuse you will receive an incomplete for the course. If you miss an exam without a valid excuse you will receive a zero for that exam.
