No, it is not a place to put cattle.Some say 260 is much harder than 250In a way, this is trueIn a way, this is false4SyllabusContact Info:Dr. Phil Womble[email protected]I travel A LOT! Email is the best way to find me.I usually don’t read my email at home so usually email after 5 pm is not answered until the following morning.Particularly on Homework Night!You are always welcome to come out to the API and ask questions.5Overall GoalsUniversity Physics II is an introduction to Electricity & Magnetism for students in the civil and mechanical engineering degree programs. The emphasis will be on developing problem solving skills and understanding the basic concepts and definitions used in the study and application of Electricity & Magnetism. Also an understanding that these concepts are not independent of other fields of physics but part of the larger picture of physics will be emphasized. Finally, we wish to give the student confidence to tackle simple wiring problems in their home and their work environments. Of course, we will not be held liable for any fires, deaths, and general mayhem which may result6Grade Weighting Factors3 In-class exams are worth 60% (20% each)Final Exam is worth 30%Homework is worth 10%73 In-class ExamsEach worth 20% of your final gradeUsually, 5 problems long.I supply all the formulae that you need (and some that you don’t need)30 minutes of the class period before an exam is dedicated to test reviewI hand out old exams for you to reviewThese “practice” exams are examples of problems and problem-types that I have previously given. Do not expect a problem to be repeated in its entirety from a practice exam.8Exams Cont’dExams consist of 80% of homework/class examplesAgain, these are not exact copies but very close20% of the material is based on classwork/homework but will be an entirely new situationI call it “the joker problem”9Exam Schedule (tentative)Tuesday, Feb 14thThursday, Mar 4thThursday, April 10th10“The More Work Shown, The More Credit Given”This phrase is repeated at the beginning of EVERY testIt means that I grade on your problem-solving capabilities not an answer.I could care less if you ever got a correct answer in this class. BUT YOUR PROBLEM-SOLVING TECHNIQUE SHOULD BE GOOD!11Final ExamEssentially a two-hour in-class examWe will review during the final class periodConsists of 10 questionsComprehensive!12Final Exam ScheduleTR 8:00-9:20Tuesday, May 6th , 8:00-10:00 am13How to Write Up a Physics Problem for TestsDraw a diagram (if possible)Label all forces, angles, etc.Assign variables to the problemDon’t just use math, write what is going on in your mind. Define what you need to findDefine what initial values you haveIf nothing else, perform dimensional analysis i.e look at the units!14STEP ZERO: Convert to SI unitsWhy?Fundamental electrical units such as volt, amp, ohm, and farad (among others) are SI units.Our equations are set up to give us SI unitsIf you see 4 0 then or just 0/4, then the equation is set up for SI unitsSo your first step is always to convert to SI units!HomeworkHomework is a group of PDF files on the serverYou must print out the pages, perform your work within the allotted space.Answers must be neat! I have instructed my grader to not give credit if they do not understand a solution.The burden of proof that you have solved the homework correctly lies on you!1516HW Due DatesHW Due Dates have a tendency to “slide back” but never “forward”.17Collaboration is more than CopyingAs adults, you are on your honor to ensure that you do not copy your homeworkThere will be no one to copy from on a test. Therefore it is in your best interest to understand the homework.It is in your best interest to be selfish.It is in your best interest to help your classmatesNo one really knows a subject until they explain it to someone else.18AttendanceI don’t have an attendance policyYOU are responsible for everything that I say in classI have a tendency to ad-lib from these notes and these “ad-libs” may also be on the exams.These notes will be placed on the Physics 260 server (under “Course Info” on the Physics
