Physics 232 is the second course in a three-semester, calculus-based, introductory-physics sequence.  This sequence explores the nature of matter and its interactions:  Mechanics (Phys. 231), Electricity and Magnetism (Phys. 232), and Wave Phenomena, Thermodynamics, and Quantum Mechanics (Phys. 233).  Throughout this sequence, you will engage in the physics program – applying just a hand-full of fundamental principles to model the behavior of diverse systems.  Those of you who’ve taken 231 will be familiar with the emphasis of understanding over technical tricks, though you should find this semester on E & M conceptually and technically ‘rich.’

 

Policies and Expectations

 

Reading: To get the most out of our class time together, read the appropriate sections of the text first.  As you read, jot down things you’d like us to address when together. When you come to a red-Question-box, stop and think about the question (that’s actually what the authors call them, “stop and think” questions.)  They’re generally quite simple, but they help you to keep alert. In addition, you’ll be required to do some short exercises and experiments as homework.

Homework 30% of your grade. There are three types of homework: Reading Exercises, Short Experiments, and Homework Problems.

Reading Exercises: (10%) In the syllabus you’ll see daily RE (for “Reading Exercise”) assignments.  They pertain to the day’s reading and are due at 10:00am before the class in which that reading is discussed.  While reading the text, you’ll encounter exercises scattered throughout.  These are generally trivial applications of ideas just presented; doing them helps you remember the ideas and avoid silly errors later when it counts -in real ‘problems.’  You’ll do almost identical problems online.  The beauty of these is that you can get instant feedback on whether or not you’ve gotten them right, and you can redo them until they are right.  Here’s how to access the RE assignments.  Log in at www.webassign.net. Make your login the same as your Redlands login (firstname_lastname), your institution is “redlands”, and use whatever password you like. The class key is: redlands 7955 5058

 

Short Experiments: (5%) You will be given a desktop experiment kit, and you should buy a lab notebook with gridded (as opposed to lined) pages, for example, the green (not black) covered “composition” notebooks at the bookstore.  During chapters with experiments (14, 17-20), bring your lab notebook to class as we will discuss and reproduce some of the results. The results of the experiments must be recorded in the notebook along with the date they are performed. You should also include any explanations or calculations in the notebook. Write enough so that you can understand what you’ve done without referring to the textbook. The notebooks will be collected periodically for grading.

 

Homework Problems: (15%) Weekly homework assignments consist of more involved problems than are found in the Reading Exercises.  Unlike the Reading Exercises, your work (not just the final answers) must be turned in and will be graded; thus the work must be legible and easy to follow (if your original work is not, you may want to copy it over.) Because good problem solving style and communication are crucial to success in advanced courses, you will be graded not just on the quality of your solution, but also on the quality of your communication.  For one thing, this means explaining your reasoning in words as well as doing the math. You must also include units anywhere you use numbers (not just at the end) and use proper vector notation when appropriate. You may find the problem solving technique / template (found on the website) helpful in organizing your work on these problems. Feel free to consult with each other or with me, but the work turned in must be your own.  You’ll also work in small groups on select problems during class / lab periods; if not completed during class/lab, you may be asked to turn them in later.  Homework Problems will be due at 10am the Tuesday after we conclude a chapter unless otherwise noted in the schedule.  No late work will be accepted, so pace yourself accordingly. Some problems will be more difficult than others, so don’t wait until the last minute to start and discover which you’ve got. If you have worked seriously on a problem without success, stop and get help from the instructor or another student before continuing.  Although you are encouraged to discuss problems with your classmates, copying someone else’s work or allowing your work to be copied is cheating and will not be tolerated.

Homework Grading: All weekly homework is graded on a 3 point scale: Check-plus (3), Check (2), Check-minus (1), Zero (0). You have until the following Tuesday to review the solutions posted outside the classroom and correct your answers for a re-grade. NOTE: Do not just attach a separate sheet of paper with the correct solution, but actually note on your homework in a different color pen, where you went wrong and correct it. Correcting all of your mistakes can net you up to two (2) additional points on your homework. There is therefore no reason you cannot have a perfect homework grade for the class by the end of the semester.

Laboratory Experiences: 20% of your grade. Non-exam weeks, there will be laboratory experiences. These are of two types: experiments and simulations.  In the experiments you observe and analyze the behavior of physical systems; in the computer simulations you employ the theory to model physical systems.  As it was in Phys 231, the modeling will be done in VPython in the classroom.  You can (but are not required to) install VPython on your personal machine; it is available for free at http://vpython.org.  You may wish to (but are not required to) bring a thumb drive to class to take your programs home; many of the simulation instructions include suggestions on how you might adapt and extend your programs.  No previous programming experience is necessary; you will learn what you need along the way.  Formal lab reports will be required for only one of the more involved experiments. Details about the report will be given later. Dr. Hill will be your lab Professor.

Quizzes: 10% of your grade.  There will be a short quiz over (almost) each chapter.  As with the Homework Problems, you will be judged not only on the correctness of your solution, but also on the quality of your communication (of course, in a nod to time constraints, the standard will not be as high as for homework).  The quizzes are intended to encourage you to look over the homework solutions and review anything that you didn’t understand.  Equation sheets will be provided (and are posted online) – familiarize yourself with them so you know how to use them and what material you’re responsible for knowing.

 

Exams: 40% of your grade. There will be two mid-term exams (11% each) and a final with a section on the last third of the class as well as a cumulative section (18%). All exams will be closed book, closed notes.  As with the quizzes, quality of communication, as well as solution, counts.  Some equations will be provided; the most fundamental principles must be committed to memory.  Sample exams will be available in class and on the website.  The final is 9:00am on Thursday, April 24th.

 

 

Grade: If at anytime you are interested in reviewing your standing in the course feel free to give me a call, send me an e-mail, or drop by my office.
