Other books you may also find helpful for the class are: Shaum s Outline College Physics. Frederic Bueche, Eugene Hecht. A very useful aid for both Physics I and II, especially in the clarification of concepts. Contains the basic theory (in form of notes) and a large number of solved and unsolved exercises. 3,000 Solved problems in Physics (Shaum s solved problem series) Alvin Halpern. It contains no theory but only solved exercises covering the material of both Physics I and Physics II. Very useful in the clarification of techniques and methods for solving exercises from basic up to intermediate to advanced level. SARC: Check the Student Academic Resource Center website (www.sarc.sdes.ucf.edu) for the days and times of tutoring sessions for this course. They are very helpful. SARC is located in HPH 115. Laboratory: The laboratory component of PHY 2054C covers materials related to class lectures and it is required for all students enrolled in the course. The laboratory score will determine 10% of your total score in PHY2054C. Course Description and Requirements: PHY2054C is the second of a two-semester sequence in introductory physics, offered primarily for students majoring in information technology, the biological science and pre-health professions. Emphasis is placed on understanding major principles and concepts and concepts. Algebra with simple Trigonometry is used to clarify them. Students should have a good working knowledge of Physics I, Algebra and Trigonometry at the level of MAC1104 and MAC1114 or equivalent. Information about this course (syllabus, class-notes, etc.) will be available at the website
www.physics.ucf.edu/~cvelissaris/summer11/phy2054. The website will be frequently updated as the course progresses itself. This is a very fast paced course. The content of this course is selected to match nation-wide standards for Physics courses, which are often used to prepare students for careers in Medicine and Life Sciences. During the course we will typically work one chapter per week. Your primary sources of information for the new concepts are your instructor, the textbook and your class notes. The syllabus shows which sections you need to read for each day of class. Here is an estimate of the effort needed for 2054C: Reading 20-30 pages of text each week 3 hours. Web based homework & time studying concepts 5 hours Laboratory 3 hours Classroom time 3 hours Estimated weekly effort 14 hours You can see that you need to plan on having enough time to do your best in this class. It is extremely important NOT to get behind! Physics builds on itself inexorably, and once you are behind it will be very difficult to catch up with it again. And don't assume that because you read a section, you understand it. Until you can consistently do the problems successfully, you don't understand the material. Course Objectives: The primary objective of the course is to study and understand the electromagnetic field and electromagnetic interactions. The topics we will cover are: Electric charges and the electric interactions. Coulomb s law. The Electric Field and the Electric Field lines. Electric flux and Gauss law.

Plane, concave and convex mirrors. Images formed by mirrors. Ray tracing and the mirror equation. Refraction of light and Schnell s law. Dispersion of light. Lenses and image formation from lenses. The thin lens equation and the magnification equation. The human eye. Magnifying glass. The telescope and the microscope. The wave nature of light. Constructive and destructive interference of light and Young s double slit experiment. Diffraction of light and resolving power of optical instruments.
The mission of the course is to learn how to think quantitatively and how to express the laws of Nature by using the language of Mathematics. You do not need to memorize the formulas you encounter but you have to master a number of important concepts and know how to apply your knowledge on a broad range of problems in Science and/or Technology. The goal of this course is to help you enter the world of Science and Technology. The best way to achieve this goal is via homework problems. Homework plays a central role in this course. If you have understood the underlying concepts the exercises are straightforward, but if you are trying to guess the right equation you will fail unnecessarily. Since homework is so important for your understanding the material expect approximately one per week. No homework extensions will be given. It is the opinion of your instructor that working through problems is the best way to master the material of this course. Homework: Assignments will be submitted on the www.webassign.com web site. You can get an access code for this web site with every new book you buy or you can purchase an access code at the bookstore or via the web. The WebAssign name of this class is PHY2054_B001_Summer11 and you will have to self enroll to the class. Instructions on how to self enroll you can find at the booklet distributed along with the syllabus or at the file www.physics.ucf.edu/~cvelissaris/summer11/phy2054/syllabus/webassign_self_enrollment.p df. A short introduction to webassign can also be found at www.physics.ucf.edu/~cvelissaris/summer11/phy2054/webassign and at www.webassign.com/info/students.html (then go to Student Guide). WebAssign phone support is also available for students and a 1-800 number can be found at www.webassign.com/info/contact.html. There will be one assignment approximately every week, with 5 to 10 exercises and problems. Each student must submit an individual solution set. Fifteen percent of your grade will be determined from your average homework score. In order to successfully self enroll you will need a class key. The Class Key is for you PHY2054_B001_Summer11 class is (case sensitive): ucf 3695 3522 which you can also find it in the self enrollment guide. Your average Homework score is going to contribute 15% towards your net class score. Your average Homework score is the average from all individual homework scores (expressed as a percentage). There will be one Homework Assignment per chapter and each one will contain 5 to 10 Exercises. It is imperative to understand these exercises since exam philosophy will be drawn from the concepts and solution techniques encountered in your Homework. Feel free to discuss your homework assignment with your instructors during your recitations.
You will have approximately one week per Chapter. Homework extensions in general are not given for free. If you ask for an extension you will be penalized -15% per extension (that is if for example your actual score is 80% for the homework, with one extension you will receive only 65%). Exception is the first Homework where there will be no penalty since it is considered a learning period for WebAssign. Please note that no extensions will be given after the last day of classes. No homework credit or extension is going to be given after that day. Your instructor will allow WebAssign 15 trials for Homework problems. Important: Unless otherwise specified WebAssign is looking for an answer with 3 significant figures within 1% of the correct answer. Problem Sessions and Attendance: The first hour of your lab session will be devoted to supplementary instruction as well as building up your problem solving skills. Your Lab Teaching Assistant and/or your class instructor will be solving a number of problems. The recitation problems are from your book and they are given at the end of the syllabus with the class schedule. These problems will also be part of your Homework Assignment. Your recitation instructor will also answer any questions you have about Physics and/or assist you with the solution of any other exercise you want. It is imperative to understand the recitation and homework problems since exams/quizzes will draw heavily from the concepts and solution methodologies encountered in these problems. Attendance at the recitations will be kept. A perfect recitation attendance will grant 5% towards your final net score. If your recitation attendance is not perfect then your attendance score will be modified accordingly. Your lab grade will be based on your lab report and will be different from your recitation attendance. For more information consult your laboratory Syllabus. You are free to collaborate among yourselves towards the solution of these problems. In fact collaboration and peer instruction is strongly encouraged and advised. Feel free to ask the recitation instructor of any questions you may have. Bring with you a calculator, your Physics textbook, your class notes or any other notebook you have and you think it is helpful. The recitation schedule, along with a list of all recitation problems is provided with this syllabus. A pdf worksheet with the recitation exercises per Chapter will also be placed at the web by your instructor. The location of the file is at: www.physics.ucf.edu/~cvelissaris/summer11/phy2054/s. Please, before you come to your lab make a hard copy of the file and try to solve the exercises by yourselves. Examinations: There will be one midterm exam which will contribute 35% towards your total class score. A final examination will also contribute another 35% to your total class score. The exams may be problems to be worked out, multiple choice questions, or a combination of two. You must have with you at least one number two (2) pencil, and a computer scored answer sheet (a pink scantron) at every exam. You MUST accurately record your student ID number on the proper location of the Test Form on each written exam so that the computer can keep track of your scores as the term progresses. A non-graphing, non-programmable calculator may be used
during exams. The Office of Disabilities Services will provide reasonable accommodation to students with disabilities. All problems from in-class exams will be reviewed in class during lectures. A valid UCF photo ID card is required when you turn in your exam answer sheet. CLASS ATTENDANCE IS VERY IMPORTANT SINCE MANY OF THE EXAM QUESTIONS WILL BE DRAWN FROM THE CLASS LECTURES, DEMONSTRATIONS, EXAMPLES AND DISCUSSIONS. TAKING GOOD CLASS NOTES IS ESSENTIAL. Missed Work Policy: Make up or missed work will be permitted for the following reasons: Family emergency, religious observance, University sanctioned activities or bona fide medical emergency. Authentic justifying documentation must be provided in every case, in advance for University sanctioned activities. At the discretion of the instructor, the make-up may take any reasonable and appropriate form including, but not limited to the following: a replacement exam, replacing the missed work with the same score as a later exam, allowing a dropped exam, replacing the missed work with the homework or quiz average. There will be no make up Homework or quizzes. Grading: Your letter grade will be determined from your total class score. The mid-term exam will contribute 35% and the final exam will contribute another 35% towards your total class score. Your attendance at recitations will contribute 5% towards your final score. Your homework will contribute 15% and your lab grade 10%. Your total class score will then be determined according to the simple formula: Total score in the course % = 0.35*(midterm exam %) + 0.35*(final exam %) + 0.05*(attendance %) + 0.15*(average homework score %) + 0.1*(Lab score %) Your final letter grade will be determined from your total score in the course according to the following scale: Letter Grading Scale: 100% A 90% 90% A- 85% 85% > B+ 80% 80% > B 75% 75% > B- 70% 70% > C+ 65% 65% > C 60% 60% > C- 55% 55% > D 50% 50% > F NO GRADE INFORMATION WILL BE GIVEN OVER TELEPHONE OR E-mail. All examinations will be closed book. Your instructor will provide for you a formula sheet that you will be allowed to use during you exam. The formula sheet will be also posted at the web for your convenience. In determining your grade at the end of the term: (1) The Midterm and Final Exam scores will count for everyone, and (2) The home work and attendance quizzes scores will count for everyone. (3) +/- grades will be given.
(4) If you miss one (or more) exams, you will receive a score of zero on the exam(s). (5) Curving of the net class score may be possible at the discretion of the instructor.
