Houston Community College Central COLLEGE PHYSICS1- 1401 (Lecture/Laboratory) FALL 2012 Tuesday, Thursday: 1:00- 5:00 p.m. Rooms: 403, 407 SYLLABUS Instructor: Dr. Ying Yi e-mail: ying.yi @hccs.edu Office hours: By arrangement or immediately after class times. Course description Non –calculus based study of fundamental principles of physics including mechanics and thermodynamics. Topics include motion and forces, work and energy, momentum, and the thermal properties of matter. Also students will carry out experiments which allow them to apply, verify and discover concepts and laws of Physics. You will get practical knowledge and skills for a well–rounded understanding of physics and the physicist’s way of looking at the Universe. Goals To develop a conceptual understanding of physics principles of Mechanics and thermal properties of matter and experimental method of scientific investigation and get the experience in the actual handing of laboratory apparatuses. Student objectives Students should be able to apply the principles of Physics in real-world situations. Students should be able to develop problem solving and critical thinking skills. Students should be able to develop experimental skills. Students should be able to develop skills to analyze obtained results involving error analysis. Students should be able to develop investigative and observation skills. Students will be able to develop an appreciation for logical qualitative and quantitative reasoning. Students should develop an appreciation of Physics Lab as a coherent body of knowledge as a human accomplishment. Textbooks PHYSICS (9th Edition ) John D. Cutnell & Kenneth W. Johnson ISBN: 0-471-66315-8. John Wiley &Sons, Inc. CIOFFARRI’S EXPERIMENTS in College Physics by DEAN S. EDMONDS. JR., 10th Edition ISBN: 0-669-41830-7. Houghton Mifflin Company Materials Students are expected to bring scientific (graphic) calculator Prerequisite knowledge: Students are expected to have sufficient knowledge of Geometry, Algebra 2 and Pre-Calculus Testing: You will be given 3 exams and 1 comprehensive Final. Homework: To pass College Physics1, you must do each and every homework assignment. In order to fully grasp the Physics concepts and laws and build your problem-solving skills it is crucially important that you practice. All homework assignments have to be submitted every Monday at the beginning of the class. Late homework can not be accepted. Free on-line tutor is available on website: http://hccs.askonline.net/ Class participation: In-class problem solving and discussions are important parts of this course Lab Homework reports: You must prepare a Lab Homework report and hand it in at the beginning of the next class. The report will be graded and returned as soon as possible. The report should include: 1) A title page (Your name, the date, the name and number of experiment). 2) The instructions sheet (The description of the objectives, the theory, the apparatus (equipment), and the procedure). 3) All original data and observations (You enter them in the blank data table provided) 4) All the required calculations 5) Graphs and diagrams. 6) A summary and discussion of the results. Grading Policy 3 Exams 35% Final 30% Homework 10% Lab Report 20% Performance 5% Note that the lowest exam will be replaced by Final, if Final is higher. Your grade will be based on the percentage you have earned of the available points as follows A: 90-100 % B: 80-89 % C: 70-79 % D: 60-69 % F: less than 60% Attendance Policy The HCCS attendance policy is stated in the Student Handbook. “Students are expected to attend classes regularly. Students are responsible for materials covered during their absences, and it is the student's responsibility to consult with instructors for make-up 2 assignments. Class attendance is checked daily by instructors. Although it is the responsibility of the student to drop a course for nonattendance, the instructor has full authority to drop a student for excessive absences. A student may be dropped from a course for excessive absences after the student has accumulated absences in excess of 12.5% of the hours of instruction (lecture and lab).” Note that 12.5% is 3 classes for this class. I understand that sometimes special circumstances may arise that prevent you from attending the class and if you are in this situation, please inform me about it. I will try to accommodate you as best as possible but please be aware of the attendance policy. Attendance, timeliness, and class participation are the 3 corner stones in the learning process. Being late to Physics class is disrespectful to your classmates and your instructor. Last Day for Administrative and Student Withdrawals For this semester this date is November 12, 2012 4:30PM. IT IS YOUR RESPONSIBILITY TO DROP THIS COURSE IF YOU DECIDE YOU NO LONGER WISH TO TAKE IT. Please do not rely on me or the college to drop you if you stop coming to class. If your name appears on the final grade roster at the end of the semester, you will receive a grade. I urge any student who is contemplating withdrawing from the class to talk to me first, as you may be doing better than you think. Either way, it is in your best interest to talk with me first. If you need assistance, I am here to help.

Each class I will let you know the reading assignment for the next class. Therefore you will get an idea what I will be talking about next class. * Don’t wait until the last minute to do the homework. Begin homework assignments several days before they are due. You can surely do some of them even before hearing about the topic in lecture. * Get help if you need it. Being completely stuck is no fun. If you really are getting nowhere, and have no idea what to do next, you are encouraged to cooperate with other students, or seek help from your instructors. * Do the arithmetic, with units. Substitute numbers with units in your equation. Power P = I V becomes P = (8.0 A)(24 V ) = (8.0 C/s)(24 J/C ) = 192 J/s = 192 W. 5 Keep the units on everything until the end. It’s a useful check. * Write down the answer, with correct units! * Does the answer make sense? Is the number of reasonable size, not excessively large or small? If you change the given numbers to very simple cases, will you get an expected result? If you modified the situation into a simpler one, will your approach still work? * Enjoy the challenge. Hey, you figured out something new. Now you understand it. And it wasn’t so simple. Have confidence, you can do as well or better on the next problem! *Don’t just memorize everything, try to understand! 6
