Office Hours: Monday, Wednesday, and Friday 12:20 p.m. 1:30 p.m., after class or by appointment. We can agree on a time to meet me if you talk to me after class or if you send me an . T.A.: Nisha Baral T.A. Office: TBA nishabaral@knights.ucf.edu T.A. Office Hours: TBA Textbook: The required Textbook for the class is: COLLEGE PHYSICS A Strategic Approach Volume 1 (3rd edition) by Knight, Jones and Field (Pearson Publications) and Physics 2053 lab manual. The UCF bookstore carries a customized Volume 1 of our course textbook. The package includes the access code to the website that you will need for Homework submission as well as for the in-class interactive response system Learning Catalytics. At the masteringphysics.com website you can also have an e- version of the book. There is no guarantee that you will use the same Textbook for Physics 2, therefore you will probably be better off just getting Volume 1 instead of buying the whole book. Your text book covers the concepts and the mathematical techniques that you will meet in Physics I. Other books that you might find helpful for this 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.

2 SARC: Check the Student Academic Resource Center website ( for the days and times of tutoring sessions for this course. They are very helpful. Laboratory: The laboratory component of PHY2053C 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 PHY2053C. Problem Recitation Sessions: The first hour of your lab session will be devoted to supplementary instruction as well as building up your problem solving skills. Your class instructor will also be your recitation instructor. Your instructor will solve a number of problems for you taken from a recitation problem list provided at the end of the syllabus. Most of your Homework will also be drawn from these problems. Your instructor will also answer any questions you have about Physics and solve for you any other problem you want. The recitations should coincide with your class schedule. Part of your lab grade will be drawn from your recitation attendance. Your instructor will hand you a worksheet with a couple of important problems related to concepts you have been taught in the class and/or have heard during the recitation hour. At the end of the problem recitation hour, you will hand your work to your lab GTA who in turn will grade your worksheet. Your score is going to be part of your overall lab grade. It is imperative to understand these recitation problems since there is a great possibility to encounter similar questions or problems in your quizzes or exams. You are free to collaborate among yourselves towards the solution of these problems. 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. The Recitation Quiz problems will be drawn from that list. Course Description and Requirements: PHY2053C is the first of 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 and Algebra with simple Trigonometry is used to clarify them. Students should have a good working knowledge of Algebra and Trigonometry at the level of MAC1104 and MAC1114 or equivalent. Information about this course (syllabus, class-notes, etc.) will be available at WebCourses. 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

3 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 2053C: Reading pages of text each week 10 hours. Web based homework & time studying concepts 10 hours. Classroom time 7.5 hours. Estimated weekly effort 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 emphasis of this course is on motion and how things move.

6 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 web site. The UCF bookstore carries a customized package of the textbook along with a masteringphysics.com access code. You can also purchase a standalone access code at the bookstore or via the web at Here are the steps you need to do in order to enroll yourselves at your Physics 1 mastering physics.com course. 1. Go to website 2. Enter the course ID: PHY2053Spring15Velissaris 3. Buy an access code or enter the access code you purchased from the bookstore as a standalone code or with the textbook.

7 4. Continue with your Registration to the class. There is also a youtube video showing how to register yourselves at masteringphysics.com: _roeb1yau93wz&index=2 Your average Homework score is going to contribute 10% towards your net class score. Your average Homework score is the average from all individual homework scores (expressed as a percentage). You may count that there will be one Homework per chapter and each Homework will have between 5 and 10 Exercises. It is imperative to understand these exercises since the exams will be drawn by your Homework. Feel free to discuss your homework assignment with your instructor during your recitations.

8 You will have approximately one week per Homework. Homework extensions in general are not given for free. If you ask for an extension you will be penalized -10% per extension (that is if for example your actual score is 80% for the homework, with one extension you will receive only 70%). Exception is the first Homework where there will be no penalty since it is considered a learning period for the masteringphysics environment. Please note that no extensions will be given after the last day of classes. In-Class interactive Response System: Attendance will be measured via the Learning Catalytics web enabled Response System. It comes together with your Mastering Physics Account therefore you will not need to get a separate access code. However Learning Catalytics requires that you have with you a Wi-Fi enabled device such as smartphone, tablet, ipod Touch or laptop every time in class. Please contact your instructor immediately if this is a problem for you so that we can come up with a solution. The Learning Catalytics online Response System will take the place of the more familiar clicker questions. A student having successfully completed all in class quizzes (100% perfect attendance) will obtain 5% (0.05*100%) towards his total class score. If a student completes only a portion of these activities he will gain that portion of the maximum 5% (e.g. 80% completion of the attendance activities will grant the student 80 x 0.05 = 4% towards his total score.) Examinations: There will be three midterm examinations and the best two will contribute 20% each towards your net class score. The comprehensive 170 minute final examination will contribute 25% toward your net 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 also MUST know your student ID number and record it accurately in the proper location on the Test Form and 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. THERE WILL BE NO MAKE-UP EXAMS AND NO EXAMS WILL BE GIVEN EARLY OR LATE. CLASS ATTENDANCE IS VERY IMPORTANT SINCE MANY OF THE EXAM QUESTIONS WILL BE DRAWN FROM THE CLASS LECTURES, DEMONSTRATIONS 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 Interactive Lecture Demonstrations (ILDs), quizzes (if any) or Homework.

9 Grading: Each of your best two mid-term exams will contribute 20% towards your total score. The final exam will contribute another 25% towards your total score. Your Attendance at the Interactive Lecture demonstration Activities will contribute 5% towards your final grade. Your home-work will contribute 20% and your lab grade will contribute 10%. Your total (final) score will be determined according to the simple formula: Total score in the course = 0.20*(best midterm exam score) *(second best midterm exam score) *(final comprehensive exam) +0.05*( Learning Catalytics Questions)+ 0.10*(average homework score)+0.2*(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 85% 85% > B 75% 75% > C 60% 60% > D 45% 45% > F NO GRADE INFORMATION WILL BE GIVEN OVER TELEPHONE OR . 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 ILD activities scores will count for everyone. (3) +/- grades will NOT be given. (4) Since the best two midterms are counting you may miss a midterm exam. (5) If you miss the final exam, you will receive a zero score on the exam. (6) Curving of the total class score is possible at the discretion of the instructor. Important Dates: Classes begin: January 12. Drop Deadline January 15. Add deadline: January 16. Withdrawal deadline: March 24. Classes End: April 27 Disclaimer: The instructor reserves the right to make changes to the above syllabus. Any changes will be in effect only one week after announced to the students. The latest version will always be available on the class web site.
