Physics 1110 — General Physics 1

Fall 2006 Information

 

Version 060829

1       General Information

1.1      Content description

Physics 1110, General Physics 1, is the first semester of a three-semester calculus-based introductory physics sequence.  Our physics focus primarily concerns mechanics: the how, when, and why things move or donÕt move.  Towards the end of the semester, we will also investigate the physics of heat and thermodynamics.  Our goal is for you to learn to approach, solve, and understand a wide variety of physics problems on both qualitative and quantitative levels, and to relate Òclassroom physicsÓ to the real world in which we live.  We will emphasize conceptual understanding along with problem solving skills.  We will begin with a study of linear motion and mechanics (forces, masses, and acceleration) associated with the world-changing notions and discoveries of Galileo and Newton.  We will see that conservation laws (e.g. energy and momentum) provide a wonderful and powerful alternative for understanding physics and solving problems.  We will continue with applications and extensions of these fundamentals, including, for example, rotational motion and vibration.

 

Problem solving will be strongly emphasized throughout the course.  This is much more than simply learning which formulas to apply: we will work towards gaining the skill and confidence to use intuition – to test and understand solutions, not just ÒarriveÓ at them.  Accomplishing this will require your patience and most of all practice.  Skill is acquired by working through homework problems.  I expect you are aware that mastery of any art or athletic discipline involves a great deal of practice, often considerable repetition of exercises designed to enhance your skills, exercises that are often not particularly beautiful or enjoyable.  Mastery of physics is the same. 

 

The course includes both classroom and laboratory components.  Prof.Õs Dana Z. Anderson and Ed Kinney will jointly instruct the class.  Primarily, though not exclusively, Prof. Anderson will responsible for the lecture periods and exams, while Prof. Kinney is primarily responsible for the homework, recitation sections and working with the teaching assistants.

To be announced

 

Web Site

The course web page will be used to make announcements and post reminders.  It is a good idea to check it daily.  A course calendar, solutions to the homeworks, and exams will also be posted there as well a summaries of the lectures.  Concept tests and their answers will appear on the web after the lectures.  The URL is http://www.colorado.edu/physics/phys1110/phys1110_fa06.

2.1      Communication

In December 2001, the University announced that e-mail would be an official means of communication, so that students must have e-mail accounts on reliable systems and must check their e-mail regularly. In this course, we will assume that any announcement sent out by noon on a given day, is known by everyone by 8am the next morning. It is probably wisest to check at least twice a day. Be aware that Hotmail occasionally delays the delivery of email by several days, so it is not recommended.

 

3       REQUIRED MATERIALS

Text and Workbook

Physics for Scientists and Engineers – A Strategic Approach, by Randall D. Knight, Volumes 1 and 2, and Tutorials in Introductory Physics + Homework, by Lillian C. McDermott et al.

 

Online Assignment Access

You will need a Student Access Kit for Mastering Physics.  Mastering Physics provides online homework assignment access. The Access Kit is bundled with yet another workbook but we do not use the workbook. 

 

Remote Response Devices

Individual remote response devices are required to respond to in-class knowledge questions.  These ÒclickersÓ are available at the bookstore.  Each individual clicker must be registered at http://capa.colorado.edu/cgi-bin/RegisterAFS

4       Expectations

4.1      Reading and preparation

In order to promote the greatest information transfer during the lecture period you, as the student, are expected to read and carry out any other assigned material before class and be prepared to participate in class discussions.  Reading assignments are provided in the course calendar. We will cover approximately one chapter of the textbook per week. 

 

Reading the book is an essential part of this course.  As mentioned above, students are expected to have completed the reading assignments prior to the lecture.  The lectures are designed with the assumption that students have carried out the reading, and therefore it is ineffective to rely solely on the lectures to understand the material. 

4.2      Recitations

In addition to lectures, the course is organized so that each week on Thursdays you will meet in much smaller groups for an hour.  Much of the focus will be on working through Tutorials text that accompanies your Knight texts.  You must bring the Tutorial text to recitation.  You should also bring a blue, red, and black colored pencil, as well as a short (say 6Ó) ruler.  As is true of the lecture, attendance is mandatory and a portion of your grade will be derived from participation in these recitations. An online pretest on the material you cover on Thursday will be due by 8am Thursday morning; there will be a weekly assignment from the Tutorial Homework as well, which will be due promptly at the beginning of recitation.

4.3      Arriving & departing the classroom

Students who attend class are expected to arrive on time (on the hour) and leave after the instructor has completed the lecture, which will usually be about 10 minutes before the hour.  Late arrivals and early departures tend to disrupt the class in G-1B30.

4.4      Classroom behavior

Newspaper reading, listening to music, doing homework, etc. disrupt the general tenor and spirit of the interactive classroom.  Such activities are therefore prohibited.  A student found violating this policy will receive an absent mark for the lecture period, and may be asked to leave.

 

In general, students and faculty each have responsibility for maintaining an appropriate learning environment. Students who fail to adhere to such behavioral standards may be subject to discipline. Faculty have the professional responsibility to treat all students with understanding, dignity and respect, to guide classroom discussion and to set reasonable limits on the manner in which they and their students express opinions.  Professional courtesy and sensitivity are especially important with respect to individuals and topics dealing with differences of race, culture, religion, politics, sexual orientation, gender variance, and nationalities.  Class rosters are provided to the instructor with the student's legal name. The instructor(s) will gladly honor your request to address you by an alternate name or gender pronoun. Please advise the instructor of this preference early in the semester so that he may make appropriate changes to my records.  See polices at:

5       Grading Material

5.1      Exams

There will be three 90 minutes in-term exams and a final exam.  The in-term exams will be administered on Tuesday evenings, September 26th, October 24th, and November 28th in MUEN E050, MATH 100 and CHEM 140. The final exam will be cumulative and will be held on Tuesday December 19th, at 7:30 PM – 10:00 PM. 

 

The exams will be closed-book.  The instructor will either provide a formula and constants sheet, or a single formula sheet will be permitted — details will be provided prior to the exams. CALCULATORS ARE NOT ALLOWED (including those on palmtop computers, PDAÕs, PIMÕs etc).  Music players, cell phones and other communication technology may also not be brought to the exam.

5.2      Problem sets

Problem sets will be assigned weekly, generally on Wednesday except when it falls on a holiday. We will be using a new interactive on-line homework system called "Mastering Physics."  Your homework solutions will be entered into the computer directly, with instantaneous feedback given.  Online hints will also be available for those that need them. Homeworks will generally be due on Wednesday evenings at the time listed on the Mastering Physics homework page. On exam weeks the homeworks will be shortened somewhat and the deadline extended until Thursday evening.  Note that even for a few days past the due date you will be able to work on the problems, but at a reduced score.

 

Please be patient with us if there are some initial bugs.

 

1. Go to  www.masteringphysics.com  

 2. Click on the Knight book cover

 3. Click on the Register button

 4. Enter the 30 character access code inside the pull tab in your Mastering Physics Student Access Kit.

 Fill in the information they ask for. Make up a username and password you can remember.

 5. The Course ID is MPUNIVCOLOFALL06

 6. Enter your university student ID number.

 

You are encouraged to work together on the homeworks, but each person must enter her/his own solutions. Do not fall into the trap of working with a group where others routinely provide solutions; you will have big problems with the exams, which you take alone. Using ``master formulas'' or guessing answers really destroys the learning process; try to avoid it at all costs.

 

5.3      Attendance and Knowledge Questions

Class attendance is required and in Lecture is taken using the remote response devices (ÒclickersÓ). There will be frequent in-class questions with responses recorded by clickers. Therefore you will need to bring your "clicker'' or electronic transmitter to lecture each day to be used for audience feedback.  You will get extra credit towards your exam scores based upon your clicker usage as follows:  Throughout the semester you well get one point for each response to a question and three points for the correct response.  Your total clicker score will then replace up to 10% of your exam grade using the following algorithm: {(1-0.1c)*x + 0.1*c} where  x=exam  score and c=clicker score, both normalized to one.  Therefore, if you get an exam grade of 75% (x=0.75) and all clicker questions correct (c=1) you will get an exam score of {0.9*.75 + 0.1*1}=.775 or a final exam score of 77.5%. 

6       How to succeed in this course:

The course topics that we will cover in Physics 1110 are among the greatest intellectual achievements of humans. Don't be surprised if you have to think hard and work hard to master the material. You can perform very well in this class if you follow this time-tested system:

 

 

7       Grading and Policies

7.1      The No Excuses, No Questions Asked, No Negotiation, No Penalty Policy.

We accommodate all forms of personal circumstances that lead to missed classes and late assignments by the following policy: We drop the lowest four lecture participation scores (due to absence or otherwise) and we drop the lowest two homework assignment scores.  Thus you may miss up to four lectures and two assignments without impact to your grade.  This accommodates all personal reasons for delays, absences, missed assignment deadlines and so forth due to, for example, illness, travel, athletic travel, religious activities, or just plain bad hair day.

 

As a consequence, late assignments are not accepted, and missed absences cannot be made up.  For assignments, this holds whether they are 5 days late or 5 minutes late. 

 

This policy is non-negotiable with the exception of extraordinary circumstances that are beyond the studentÕs control such as a family death or similar emergency, extended illness (however, a cancelled airline flight, for example, does not fall into this ÒextraordinaryÓ category).  Usually the student will be required to provide an independent letter (such as from a Doctor) that substantiates the circumstances and verifies the studentÕs inability to meet the course expectations over the time period in question. 

 

You may be excused from an exam only for a medical or personal emergency beyond your control. You must present written documentation to us no later than one week subsequent to the exam you missed. (Again, a cancelled airline flight does not fall into the Òpersonal emergencyÓ category, for example. And not knowing which room your exam is in is not beyond your control).  If you are excused from an exam, your grade will be based upon your remaining exam scores.  In the (unusual) case of an (at most, single) excused absence, your other exams will be used to compute an exam average. There are no make-up exams given. 

 

7.2      Grade weighting

7.3      About Curving

Grades are ÒcurvedÓ and it is useful to understand how curving is done at various stages in order to derive a final letter grade, and how curving, along with the student score distributions, can affect your grade at any given stage. 

 

Each item in the above has a numerical score for each student.  These scores are fit to a ÒNormalÓ (Gaussian) distribution giving a mean and a standard deviation.  This distribution is then ÒcurvedÓ by a straightforward formula to give a mean of approximately 75 and a standard deviation of about 13.  At that point a letter grade is generated for that score according to a standard formula that leads to approximately 10% AÕs, 20% BÕs, 40% CÕs, 20% DÕs and 10% FÕs.  Note that this process of curving mitigates the problem of excessively hard or excessively easy exams, for example.  However, also note that your letter grade can go either up or down due to the curving process.  In the latter case, you will be disappointed to see what looked like a ÒBÓ score turn out to be ÒC+Ó, but of course you will be happy if the opposite occurs.  But the fact is, the curving process indicates how you have performed with respect to the rest of the class.  Another, sometimes upsetting, outcome of curving arises when the spread of scores is very small.  If everyone receives a 95 out of 100 on an exam, that will translate to a 75% = C when the scores are curved.  ThatÕs annoying but inevitable with curving.  On the other hand, your grade would be raised to a C by curving if everyone receives 50%=F on an exam.

7.4      Course letter grade determination

At the end of the semester all of the scores for the various items are weighted according to the value in the above table and summed together, giving a total score for each student.  The scores that are weighted are the curved scores, not the raw scores for each item.  The use of the curved scores rather than the raw ones is required in order to make the weighting meaningful.  The student total weighted scores are now curved again to obtain a normal distribution.

 

This last curving is done in such a way so as to set the median class score to approximately define the C/C+ letter grade boundary. Typically this sets the class average letter grade to approximately C+.

7.5      Grade negotiation

When you receive your final grade, you should see that it is more or less consistent with your individual (curved) grades on the exams, assignments, and so on (taking the weighting into account).  If there seems to be a discrepancy, by all means speak with the instructor as the possibility of errors is real. 

 

Barring errors, the instructor is not in a position to negotiate grades as it is unfair to the remainder of the class to raise one individualÕs grade without reconsideration of all the grades.  An exception involves extraordinary circumstances beyond the studentÕs control (as in Section 7.1).  Such circumstances may well lead to a consideration for a grade of incomplete, IP or IF.
