Physics 161 Spring 09.    Course Title: General Physics II (calculus-based), Section 001, Call Number 16273, Cr 03, MWF 10:00-10:50 Regener 103, instructor is Dr. L. Kent Morrison, 277-0433, (best way to reach me), office in room 1115 of the Physics and Astronomy (P&A) Building at the northeast corner of Lomas and Yale.  This course is for physics, astrophysics, engineering, or science majors.

Text and other material.    Mandatory Text: University Physics by Young & Freedman, 12th ed.  Various text supplements are available and may be helpful but are not required. However, purchase and use of a keypad and Mastering Physics (MP) are required.  MP comes free with new texts purchased in the bookstore.  But if you bought a used text or obtained your text elsewhere you will have to purchase MP (details are given below). The problem session (Physics 168 section 001) should be helpful but is not required. The laboratory (Physics 161 L) is very relevant to the course and is recommended but is not required. You will need a simple calculator with trig functions that you should bring to class regularly._ You will need it for in-class exercises, tests and homeworks. 

Office hours and tutoring help.   My office hours will be on Mondays, Wednesdays and Fridays 1:00-2:30 pm in Room 1115 in the Physics and Astronomy (P&A) Building at the northeast corner of Lomas and Yale.  Monday from 11:00 to 11:50 I will be teaching the problems session in Regener 114 and you are welcome to drop by to ask questions when I am not busy.  If none of these times work for you then please make an appointment.  Please do not ask questions via email!  All questions regarding Mastering Physics and the I-Clicker instruction should be addressed to Cathy (see below).  With a class this size I will not have time to communicate effectively via email so make an appointment if you have questions! Other resources are:


Class rules.

Do not cheat.  Any form of cheating behavior will be dealt with severely.  I use the words cheating behavior because if you are looking in the direction of your neighbor's paper I can't read your mind and determine whether you are cheating.  But I can tell what you are looking at.  Do not wear a baseball hat or any other type hat that covers your eyes during a test. All cell phones must be turned off and placed out of sight.  If I even see a cell phone during a test the owner will receive a zero. I will not tolerate this or other cheating behavior, period.  And there are many other examples.  Use common sense about this.

Do not talk in class.  This is the most difficult problem of a large class.  Some students think nothing of disrupting other students who have paid money to learn physics.   Most students can't concentrate when others are talking.  Please leave the lecture hall if you must talk. 


Class bulletin board.  The class bulletin board is in the basement hallway of Regener (by the labs).  I will post test solutions, grades (by your three digit student ID, not using your Banner ID or SSN) and other class information there so check it often.  Make sure I have the correct grades on my spreadsheet.  If a grade is incorrect, see me right away.  Do not wait until more than 2 weeks after the grade has been posted to see me for correction.  If you don't take the lab and have no idea what I am talking about, here are directions to the basement hallway:  Exit our classroom to the outside by the east door.  Walk south about 25 yards.  Enter the door and take the steps down to the basement hallway.

Student ID  (Class ID).  If you took my P160 (section 001) course in the Fall 2008, you do not need to get another student ID or re-register your I-Clicker, but those who did not take my P160 course must obtain a three digit student ID and register your I-Clicker.  To obtain a three digit Student ID (this is not your Banner ID or your ssn) for registering your I-Clickers (keypads), go to the following website:    You will be assigned a three digit student ID which is only good for this course.  The ID’s will start at 001, 002, and go through 170 or so.  While at this website, you should also register your I-Clicker.   If you forget to register your I-Clicker at this panda website, you can go to  to register it.  Use this Student ID for your online homework, tests, in-class exercises etc.  Due to privacy concerns, DO NOT write your social security number or banner ID on anything you hand in.  If you forget your Student  ID number, you can go to the same website to find out what it is.

I-Clickers (Keypads):  We are using the I-Clicker that is used by all UNM classes.  You must purchase it from the bookstore, register it before class Wednesday and bring it to class every day.  Go to  for instructions and help on registering your I-Clicker at .

  When you register your I-Clicker (keypad) be sure to provide your name (even though the registration Website treats your name as an optional field).  Pay careful attention to distinguish between the number one and the letter L and between the number zero and the letter O.  You will need to record your Student ID (Class ID) that you obtained above (see paragraph above on “Student ID (Class ID)”) and the I-Clicker/keypad number found on the back of the keypad.  Your Student ID will identify your keypad as you use it in class, for tests, for posting grades and for Mastering Physics registration so you need to memorize it and keep it private.  Since you must have your Student ID before you can register for Mastering Physics you may start losing points for the Mastering Physics homework if you register your keypad too late



Dropping the class.  If you drop the course then please let me know.  Sometimes this information does not get to me and this can lead to grade difficulties at the end of the semester.  If you do not drop the class and stop attending, I will not know it and you will receive a WF at the end of the course!  So, it is critical that you file the appropriate paperwork and let me know when you drop the course.

Mastering Physics (MP) is the homework grading system.  Your new book came with a MP package (no extra cost to you).  If you have a used book you need to buy the Mastering Physics package from the bookstore or you can go on line with a credit card and buy it.  To buy access online, go to www.masteringphysics.com_ then click on the title of your textbook. Then click Buy Now and follow instructions.  Whether your MP package came with the text or whether you bought access from the bookstore or online, everyone must register on line and complete the first MP assignment and start becoming familiar with MP before class on Friday. 

There will be no grade for the first assignment (hw #1 is called “Introduction to MasteringPhysics”) on how to use MP.  You can register for MP simply by following the instructions available online at   Important notes for registering:  The UNM Zip code is 87131.  Our Course ID is MPMORRISONSPRING09 (careful about the letter O versus the number 0!  The first 2 are the letter O, the last is the number 0).   Your Student ID is the three digit number you are given when you register your keypad.  The first person in the class who registers their keypad will be given number 001, the next 002 and so on.  Student Access Code:  This is a six-"word" printed code supplied beneath the pull-tab inside your Mastering Physics Student Access Kit.  It is valid for registering one student. If the tab in this kit has been pulled back, the code may no longer be valid.  If you buy a secondhand textbook, any code supplied with it is probably not valid.  In either case, you can purchase a Student Access Code online using a credit card or you can go to the bookstore and buy a mastering physics package.  If you need help then click on the ? icon.  There are more detailed Mastering Physics registration instructions at
