The number of credits is 4. The course covers electricity and magnetism, field theory, and geometrical and wave optics. 2 Pre- or Corequisites PHY 2048 is a course prerequisite. Calculus II (MAC 2312) is a pre- or corequisite. Warning: it is unlikely that you will do well in this course if you do not have the appropriate math (algebra, trigonometry, calculus) background and skills. 3 Course Overview PHY 2049 is part II (electricity, magnetism, optics) of Physics with Calculus, the introductory physics sequence for students of science and engineering. The plan is to present a rigorous foundation of the principals of classical physics, with an emphasis on solving physics problems. Differential and integral calculus are used (see note in 2). Classes are lecture-style and include solving sample problems. See 8 for additional information. Page 1 of 8 Reference Date 12/13/2013
4 Course General Goals The primary goals of this course are for you 1. to learn some of the fundamental principles of physics related to electricity, magnetism, fields and optics; and 2. to learn problem-solving skills that can be applied to other areas of science, engineering and life in general. To achieve these goals it is necessary to acquire a conceptual understanding of the physical principles related to the course material, to acquire the ability to use mathematical equations to describe particular phenomena, and to develop a methodical approach to problem solving. Important steps to take are reading the text before and after class, carefully listening to lectures, working through examples, discussing questions in class and out of class with other students, and doing as many problems as you possibly can. 5 Course Specific Objectives At the completion of this course you will be able 1. to answer conceptual questions related to electric forces and fields for simple static charge arrangements (discrete and continuous) using Coulomb s and Gauss laws; 2. to understand the concepts of electric potential energy and electric potential; 3. to understand capacitors, energy storage in capacitors, resistors and energy dissipation in resistors; 4. to analyze direct-current and alternating-current electric circuits and predict their function; 5. to analyze magnetic fields generated by simple arrangements of currents using Ampère s law; 6. to analyze the effects of changing electric and magnetic fields for simple arrangements of such fields using Faraday s law; 7. to discuss the relationship of Maxwell s Equations to the phenomenon of electromagnetic waves and light; 8. to solve problems related to ray optics, image formation by mirrors and lenses, and wave optics (interference and diffraction). The level at which these specific course objectives will have been achieved will be measured and assessed through exams and graded homework assignments. 6 Textbook and Online Homework System The reference textbook is University Physics, Volume 2 (Chapters 21-36), Young & Freedman, 13th Edition, Addison-Wesley. The book comes in many different versions, hardcover, paperback, loose 2
leaf and e-book, with some of these bundled with a MasteringPhysics TM (MP) access code. Get the version that suits you best. MasteringPhysics TM is an online system for self-tutoring and homework management. Access to MP is required. If you purchased access to MP for Physics I (PHY 2048), you do not need to buy a new access code; your prior access should still work. If you never had MP access or your access has expired, you will need to purchase an access code online at http://www.masteringphysics.com. Here are some ISBN-13 numbers of various combinations/bundles: Paperback Volume 2 + MP access: 978-0-32177825-3 Paperback Volume 2, no MP access: 978-0-32175121-8 Hardcover Volume 1 and 2 + MP access: 978-0-321-67546-0 Hardcover Volume 1 and 2, no MP access: 978-0-321-69686-1 MP access alone: 978-0-321-74126-4 How to register for this class in MasteringPhysics? Go to http://www.masteringphysics.com Click on MasteringPhysics for Young/Freedman s University Physics/13e. Click on Registration and follow the instructions. You will need to enter your personal access code, your first and last name, your FIU ID number (your Panther ID), and the course code number. The course code is MPVANHAMME27616. Homework assignments will be posted on the MP system after each class (see semester schedule in 11). Unless stated otherwise, Tuesday assignments are due each following Sunday; Thursday assignments are due the following Tuesday. This means that you have about five days to work on each homework assignment. However, late submissions will be accepted but will incur a penalty. For each day the homework is submitted late, the total score is reduced by 15%. Effectively, this means that a homework score drops to zero if submitted late by about a week or more. Assignments will include self-tutoring (ST) problems for practice and end-of-chapter (EOC) problems that will be graded. Homework scores will accumulate and be part of your final grade. 7 Grading There will be 3 (three) exams (see semester plan below). Exams 1 and 2 will be non-cumulative; exam 3 (the final) will be cumulative, with approximately 2/3 of the exam on new and 1/3 on previous material. Exams will typically consist of a number of multiple choice questions and three to five problems similar to those assigned for homework. For the problems, you will need to show your step-by-step solutions. Correct steps and approaches will earn partial credit. 3
Final Grade Breakdown Exam 1 20% Exam 2 20% Exam 3 (Final) 40% Homework 20% Total 100% Letter Grades The table below shows the anticipated percentage ranges and corresponding final letter grades. Note the low cut-offs for the lower grades; a certain amount of curving has already been built into the table. 90.00 A 85.00-89.99 A 80.00-84.99 B+ 70.00-79.99 B 65.00-69.99 B Excellent work and performance Performance substantially better than expectations 60.00-64.99 C+ Performance meeting expectations 50.00-59.99 C 45.00-49.99 D+ Performance meeting some but not all of the expectations 35.00-44.99 D 34.99 F Performance fails to meet any of the expectations; complete lack of skills necessary to take advanced courses that have this course as a prerequisite 8 Study Hints and Preparing for Class Keeping up with the material is of the utmost importance. Every new chapter builds on prior chapter or Physics I material. The strict regimen of homework assignments is in part designed to keep you focused and to prevent you from getting behind. It is impossible to discuss all of the material that needs to be covered within the time allotted for class. Lectures will emphasize the main concepts and ideas and will include carefully selected sample problems. You will also be responsible for material pointed out to you in the textbook but not explicitly discussed in class. Read relevant chapter sections BEFORE we get to them in class. This will help you recognize difficult concepts and enable you to ask meaningful questions in class. After each class, study the material and make sure you understand the concepts. Follow the step-by-step sample textbook problems, as well as the examples given in class. Then try to solve the sample problems by yourself, without looking at your book or notes. Once you feel comfortable doing the sample problems, try 4
the homework assignment associated with the material. Do the self-tutoring problems first, then the end-of-chapter problems. Studying together with a group of class mates can be very beneficial and I encourage it. See 9.3 for further comments on this issue. Self-test Quizzes A number of self-test quizzes have been posted on the class Web site. These will not be collected or graded. They are meant to serve as an additional tool to test your (in many cases conceptual) understanding of the material. As we progress through each chapter, try to figure out the correct answers to quiz questions relevant to that chapter. Many quiz questions are typical multiple choice questions you can expect on the exams. 9 Course Policies 9.1 Exams Exams are closed book, closed notes. You will need to bring blank paper, pens/pencils and a calculator. A Physics II formula sheet will be provided. Laptops, tablets and devices for communication with the outside world are not allowed. Make-up exams will only be allowed in exceptional circumstances, and only if all of the following conditions have been met: (1) you have provided in writing (email is fine) an appropriate excuse for the missed exam; (2) the excuse has been submitted at the earliest practical time, in most cases before the missed exam, and (3) I have deemed the excuse to be valid. Make-up exams will be held at MMC. 9.2 Grades Homework and exam scores will be maintained in the MP grade book. You will have access to your personal record in the grade book. You are responsible for tracking your progress by referring to this record. 9.3 Homework Assignments Discussions with fellow class mates (in person or via social media), studying in groups, explaining concepts or problem solution approaches to each other are strongly encouraged. However, when it comes to submitting your homework, you are expected to be able to solve the problems on your own and to submit homework solutions and answers independently from anybody else. If you copy someone else s homework, or let someone else submit your homework, you are setting yourself up for penalties (see 10) and, even worse, for not learning. You will likely fail the exams and in the end fail the course. Do not waste your resources in such a foolish manner! 5
10 Academic Honesty This section of the syllabus summarizes important university policies regarding academic honesty that are relevant to this course. The following is a direct quotation from the FIU Student Handbook: Florida International University is a community dedicated to generating and imparting knowledge through excellent teaching and research, the rigorous and respectful exchange of ideas and community service. All students should respect the right of others to have an equitable opportunity to learn and honestly to demonstrate the quality of their learning. Therefore, all students are expected to adhere to a standard of academic conduct, which demonstrates respect for themselves, their fellow students, and the educational mission of the University. All students are deemed by the University to understand that if they are found responsible for academic misconduct, they will be subject to the Academic Misconduct procedures and sanctions, as outlined in the Student Handbook. The most frequent forms of misconduct are cheating and plagiarism. Examples of cheating include the unauthorized use of books, notes, aids or electronic sources on exams, or the assistance from another person while taking an exam. Plagiarism is the use and appropriation of another person s work without any indication of the source. Any person who fails to give credit for ideas, expressions or materials taken from other sources, including internet sources, is committing plagiarism. Declaration Submitting an online assignment or placing your name on an exam, assignment or any other course document is a statement of academic honor. It indicates that you have not received or have not been given inappropriate assistance in completing the assignment or exam and that you have complied with the University s academic honesty policies. Do not enroll in this class if you cannot accept the content of this declaration. Consequences If caught for misconduct, sanctions will be imposed that may vary depending on the nature and gravity of the offense. Possible sanctions include, but are not limited to, (1) assigning a grade of zero to an assignment, (2) assigning a final grade of F for the course, (3) filing a formal grievance. Appeals to sanctions will be handled in accordance with University academic misconduct policies as outlined in the FIU Student Handbook. 6
