PHY 2049 Syllabus

General Physics II

Ref. no. 174738

Summer 2017

This web syllabus includes more detail than the printed version.
 ==============

You are taking this class because you want a professional career as an engineer, computer scientist, or in a physical or earth science. I will help you continue to develop the critical thinking (problem-solving) skills, attitude, and physics knowledge those professions expect you to have when you leave my classroom. (Some of them will expect you to remember parts of it for the rest of your life.) This is a four credit course that meets five hours per week. The main topics covered are electricity and magnetism, including DC and AC circuits, and optics, including diffraction and interference of light waves. (The detailed course learning outcomes are given at the end of this document along with the exam schedule.) If there is time, I may also introduce you to one of the modern physics sections of the textbook.

Course Prerequisites:
You must still know algebra and trigonometry at a level that corresponds roughly to a "B" in those courses, and also apply geometry and use calculus. (See separate page for details.) Calculus is used on exams. You must have passed MAC2311, PHY2048, and PHY2048L with a grade of "C" or better and remember some key topics (such as vectors, classical mechanics, waves, derivatives, and integrals). You must also be currently enrolled in PHY2049L or have passed it with a "C", and meet the reading and writing prerequisites for PHY2048.

To repeat:

This course will make extensive use of
algebra, trig, geometry, basic calculus, and
some mechanics and waves from PHY2048.

There is little review of this material.

 ==============

Class meeting times:
MTWR 11:40-1:15 in SM 116  

Final exam: Tuesday, July 25, from 11:00 am to 1:40 ? in SM 116.

No exceptions. No early, late, or makeup final is allowed by college policy.
Plan ahead. This is a cumulative final.

Required Textbook: Essential University Physics, volume 2, SECOND edition, by Richard Wolfson (Pearson / Addison-Wesley, 2012).
The book is usually sold as a shrink-wrapped combination of volumes 1 and 2, so you should already own a copy. You do not need "Mastering Physics" or a "clicker" bundled with the book, just the book itself.

Catalog Description:
Prerequisite: grade of C or better in MAC2311, PHY2048, and PHY2048L. Corequisite: PHY2049L. Topics include electricity, magnetism, circuits, interference phenomena, and optics. Lecture: 4 hours. Recitation: 1 hour. Additional fee.

My introduction at the very top of the syllabus is a general summary of the course objectives, but the actual Course Learning Outcomes are given near the bottom of this electronic syllabus reflecting their placement on page 4 of the printed syllabus. The fact that they are near the end does not make them unimportant. Read them.

 ==============

Instructor: Dr. James Carr
Office: SM 290    (east wing, convenient to stairs opposite SM 137)
Office phone: 201-8971 (includes voice mail)    (Division office phone is 201-8499)
E-mail: carrj @ tcc.fl.edu (regular)    or   carrj : tccfl (in LON-CAPA)

Office hours:
MTWR 11:00-11:30 and M 1:30-2:00. See schedule outside my office or on CANVAS for current official office hours. Changes will be announced in class. Other times by appointment. I am "around" after class, but some days I may need to leave the office to set up the lab.

Individual Help:
Office hours are first-come, first-served. I monitor the discussion areas in LON-CAPA, and will sometimes comment. Individual help is available via e-mail (the FDBK button looks like an envelope) within LON-CAPA, but not at the last minute. Use regular TCC e-mail to make appointments or leave messages of a critical nature, such as emergencies.

 ==============

Special Academic Alert for future engineers:
Engineering schools have a very strict policy on repeating courses that make up the "core" math and science prerequisites for the major. They look at every attempt at every school attended, not just at the last grade recorded for your TCC grade point average. They may or may not ignore withdrawals, and exactly which classes are considered for admission will vary somewhat depending on your major and the school you attend. For example, PHY2049 is not included in the "core" required prior to admission to FAMU/FSU, but is included at UF.

I try to keep up on the requirements, but you should contact the school you plan to attend to learn how their policy applies to your situation. For example,the current FAMU-FSU policy (which took effect in Summer 2006) does not limit the number of attempts for PHY2049 at TCC or impose any requirements other than a minimum grade of C. Other schools may limit the number of attempts and/or include it in a "core" GPA calculation. UF considers PHY2049 to be a "core" course, only allows two attempts, and counts a withdrawal as an attempt! Check with a transfer advisor at the school you want to attend to be sure you know what they require.

In any case, do not take this class lightly. [The last day to drop with a refund, so your enrollment does not count as an "attempt", is May 18 and the last day to withdraw is July 3.]

 ==============

Important:
Because of the complexity of the material you are learning, regular attendance and regular preparation are especially important in this class. Every day matters.

ATTENDANCE:
You are expected to attend all classes. (See the Tallahassee Community College Catalog for details, including the few specific cases where an absence is excused and you are allowed to make up the missed work.) Missing class might explain your poor performance, but it is not an excuse for poor performance. I expect you to behave like the responsible professionals you plan to become.

I will administratively withdraw any student who is absent for the first two weeks of the semester, as determined by turning in a student information sheet. I will not drop anyone else because of poor attendance. If you cannot complete the semester, it is your responsibility to withdraw from the course by July 3 or you will likely earn an F.

If you withdraw from this course, I strongly recommend that you stay in PHY2049L but you need the lab instructor's permission followed by an override from the Associate Dean of Natural Science to do so.

Details on how to stay in the lab:
The college policy concerning withdrawal from a co-requisite class is spelled out on a separate page. If you withdraw (or are AW'd) from PHY2049L, the system should automatically withdraw you from PHY2049. If you withdraw (or are AW'd) from PHY2049 and don't follow the procedure described in that policy, the system should automatically drop you from PHY2049L. Because the lab is a critical resource (space in the lab determines the maximum enrollment in the course) and because most students who have kept up for the first half of the semester can pass the lab after dropping the lecture, we encourage you to complete the lab. Click here for details on how to do that.

Details on my AW policy:
I strictly enforce the college attendance requirement only during the first two weeks of the semester. A student who did not fill out an info sheet on the first day of class will be dropped with an AW grade if s/he does not attend and fill out and sign an information sheet by the start of the third week of class. If you are "present" but do not respond to my request for you to fill out an information sheet, you will still be considered absent.

 ==============

Grading:

Your grade will be determined on a straight scale, with 65% coming from 4 hour exams, 15% from homework and quizzes, and 20% from the cumulative final exam. No makeup exams.
* I will replace the lowest exam score (or a missing exam) with your % score from the final exam.

GRADING SCALE: 90-100 = A, 80-89 = B, 70-79 = C, 60-69 = D, below 60 = F.

Note: You must pass the final exam to earn an A in the course.

Exams: Each of the four hour exams counts 16.25% toward your grade. Bring pencils, an eraser, a straightedge (a spare pencil may do), and a basic scientific calculator to the exams. There is no need to bring your book or notes on exam days. See the schedule on page 4 of the print syllabus and on the course home page. The exams are hard.

There is a detailed description of some important parts of my exam grading rubric that takes up a full page in the print version of the syllabus that is available on CANVAS. Be sure to read it!

CALCULATORS:
Your calculator must be able to evaluate log and trig functions, but only basic scientific calculators (ones without alphanumeric storage capabilities) are allowed. Graphing is not necessary, and you are not allowed to use most graphing calculators (such as the TI-83, TI-84, TI-85, TI-89, TI-92, or similar calculators). (See separate page for details.) The TI-83 can be used in the lab, however, if your instructor allows it.

The only correct way to write an answer in scientific notation is 1.602 x 10-19; answers written as 1.602e-19 or 1.602E-19 are OK in LON-CAPA but will be marked wrong in both lecture and lab.

Homework:

Three things contribute to your homework grade: (1) Problems assigned and graded using the LON-CAPA system, where you submit your answers over the web. (2) Quizzes, which could be worth 2 to 6 points. (3) Turn-in homework problems, which are worth 3 to 6 points each. See the schedule in the print syllabus, but watch LON-CAPA or the course "unit" pages for updates. Your total (which is usually around 300 points, with most of the points from LON-CAPA problems) will be scaled to a maximum of 100 points after allowing 7% for possible absences.

LON-CAPA (computer assisted homework):
Each problem is worth one point if it is answered correctly before the strictly enforced deadline. A page in the print syllabus outlines some key features of the system, but the web resources include detailed information on using LON-CAPA. I encourage collaborative study groups for CAPA work. Collaboration means sharing ideas on the best method for solving the problem, not just plugging your numbers into a formula copied from someone else.

Quizzes:
There might be some short quizzes or exercises. Bring your calculator every day. Recently, most "quiz" material is being covered as an assignment in LON-CAPA, but this may change.

Turn-in homework:
You get credit for a serious attempt at the problem if you show adequate work that is neat, clear, and professional. Late work is penalized 1 point or more per day. Present the problems in the order of the assignment with the pages stapled together in the upper left hand corner. Use only one side of 8 1/2 x 11 paper. Make graphs on graph paper or by computer. Box your final answer. Put your name on the top of page 1 (where I put your grade). Fold your homework assignment lengthwise with your name on the outside under the staple. Points are deducted for sloppy or hard-to-grade work as well as major errors or omissions or obvious copying.

 ==============

Web-based LON-CAPA Homework:

Most of your homework will be assigned and graded using the LON-CAPA system (Learning Online Network with Computer Assisted Personalized Approach), where you get your assignment from a web page and submit your answers over the web (the CAPA part) and also have access to some additional learning tools (the LON part), which are in addition to the resources and information on my course website. That is why this course is web assisted. This is not a minor detail. If you cannot or do not do it, your course grade will be reduced by at least 10% (one full letter grade). If you do not have reliable web access at home, be sure you know the schedule for the TCC computer labs or the local libraries that offer web access.

Go to loncapa.tcc.fl.edu or use the "LON-CAPA" button on the course home page. Login information is in the print syllabus, and an example in a pdf document is included on the page linked below.

Click here for notes on using LON-CAPA.

The important thing about LON-CAPA is that each student gets a different version of a problem. (I also get one, which I will use when asked about a problem in class or to give a detailed solution after the problem set is due.) I encourage collaborative study groups for LON-CAPA work. You should discuss concepts and methods for solving problems. The best kind of learning takes place when you teach each other, explaining your attack on a problem. No learning takes place if someone simply tells you what formula to use to calculate the correct answer of if you simply follow an example in the book. You will get one point towards your homework total and lose 10 or 20 points when you can't do it on an exam. Be sure you know how to do each problem, and can do a different version (like one assigned to a friend in class) without looking at your notes.

Other comments on homework:

One reason for the length of this web version of the syllabus is so I can include details and explanations that I give verbally in class, thus documenting what students might not have in their notes.

Homework is due at the beginning of the class period on the date given on the assignment sheet included in the syllabus. The days that homework is due are circled on the class calendar handed out with the print syllabus.

You should be doing at least 3-5 problems every day because I assign several problems from each day's reading assignment. It is extremely important that you keep up with the homework, looking at problems as soon as they are assigned (about a week before they are do), and working them as soon as that topic is covered (one to two days before they are due). Pay attention to the schedule and start early so you have time to ask for help if needed and won't have to worry if a computer crashes just before the final LON-CAPA deadline.

Late penalties for turn-in homework vary. If the problem is worked in class, any paper turned in after class starts will get a full 1-point penalty. In other cases, you will get a full point penalty if it is turned in at the start of the next class and so on until it is worth zero. I also take off a point for omitting important elements from the solution or major math errors; otherwise I grade HW fairly easily while still giving you feedback on what you did wrong. Be sure to read my comments even if you get full marks for the assignment. These problems are now the smallest part of your homework grade, but they are your best tool to see if your careful solution is what I expect so you can practice what you will need to do on exams.

The LON-CAPA problems are considered due at the start of class, but the actual closing time for the assignment is late at night (usually around midnight). What this means is that a system or network failure that occurs during the day or in the early evening on campus will result in an extension of the due date, but you are responsible if some other network or phone line goes down or if the system crashes within an hour of the due date. I will need to know about any problem (via e-mail to my TCC e-mail account) ASAP because I will only shift the due-date if it can be done before the "answer" time for the assignment, which is normally about 10 AM the next day.

The "recitation" component of the course is not associated with a separate small class session. This course usually has a very managable class size that is smaller than any recitation at FSU. Instead, I use the days that homework is due as the time for discussion of any problems you might have with the assignment. Since you won't know if you have any questions if you have not tried them, my expectation is that you will have tried all of the problems before you come to class on the day they are due. I will not work all of the problems, but I will answer questions about them, including ones that might have come up in the "discussion" area. (Since I can see what problems are giving students trouble, I might take it up a day or more before it is due.) I will not answer the same question twice; you are expected to be in class every day.

The other "recitation" component is the use of a quiz or in-class exercise. Some might be at the start of class, to check on your reading or as a way to jump-start a discussion.

The problems I ask you to turn in on paper are generally from the textbook, but they could include the setup of a CAPA problem. These problems are graded to be sure your solution methods are consistent with what I will require on quiz and exam problems. For these I will give credit for a serious attempt at the problem if you show adequate work that is neat, clear, and professional, I allow late HW because my reason for grading the homework is to spot potential difficulties before they cost you many points on an exam, so I want you to turn it in even if you turn it in a day late. I take off points for unprofessional work because I want to encourage you to present your work in a way that prepares you to achieve your career goals.

Please note that I expect your final answer to be accurate to three or four significant figures, whereas LON-CAPA will often tolerate answers that are slightly off in the 3rd sig fig. I will mark off for inaccurate answers on exams.

Copying is a waste of both my time and yours, since you cannot benefit from my comments if it is someone else's solution. It is also a violation of the TCC Honor Code.

I strongly suggest that you do more problems than just those assigned for credit, although you should limit yourself to ones that are similar to the ones assigned in class. I will sometimes make suggestions. The odd numbered ones have answers in the back of the book, and all of these have a very detailed solution in the student solutions manual, a copy of which is in the physics area within the Learning Commons. The exercises at the start of each problem set are a particularly good way to review your understanding of each topic.

 ==============

Course Overview:
The way in which you should organize your knowledge of physics is a bit different from the way we must present the material. Key ideas like energy run throughout the course, just as they did in PHY2048. However, this course is more compartmentalized than PHY2048, and the exams reflect that organization. You have to put more effort into integrating the separate "units" of the course into a coherent whole that you can remember for future use. If you pay attention to items 1 and 6 of my study suggestions, you will have one page of equation notes for each exam and refine them into something like this structure for the final exam and future reference.

( PHY2049 Overview available as pdf for printing )

Course Learning Outcomes:

Apply Gauss' Law, Faraday's law, or Coulomb's Law to predict the electric field, force, or potential for a given situation. [Chapters 20, 21, 22, 27]

Apply Ampere's Law, along with Gauss' Law for magnetism, or the Biot-Savart Law to determine the magnetic field or force for a given situation. [Chapters 26 and 29]

Apply the basic principes for DC and AC circuits to predict the voltages, charges, currents, or energy in a circuit or simple circuit network. [Chapters 23, 24, 25, 27, 28]

Apply the principles of geometrical and wave optics to predict the behavior of electromagnetic waves, particularly light. [Chapters 29, 30, 31, 32]

Note:
You remain responsible for everything about units and accurate calculation in Chapter 1, vectors from Chapter 3, and the main principles of classical mechanics from PHY2048. You are also expected to correctly evaluate experimental evidence in the required co-requisite laboratory class, PHY2049L.

Also Note:
I spend extra time on Chapter 28 (AC circuits) to give a full treatment of driven damped oscillations and resonance, topics not covered in my PHY2048 course. Some semesters have enough time to allow me to look at examples using relativistic energy (Section 33.7) or topics from basic atomic physics (Sections 34.3 and 34.4).

For your convenience, in addition to my outline of the main topics and equations used in this course, I also make available a one-page summary of what you should still know from PHY2048. A two-page (more complete) version of supplied on the PHY2048 pages are in a separate pdf file. Comparing the two will show you what you should know (the one page version) and what you can look up when you need it (the two page version and what you should have in your study sheets for PHY2048). We will use quite a few of the basic concepts (force and energy) in PHY2049.
