$"Prof. Sung-Won Lee Dept. of Physics Texas Tech University Welcome to the Physics 1408-002 Principles of Physics I Spring, 2009 Class room: Science Building Room 7 1/8/2009 %"Syllabus: PHYS 1408, Principles of Physics I, Fall 2008 !"Class Time and Attendance !! You are expected to read the chapters indicated in the “Class Schedule” before coming to class. I will assume that you have read the material and we will discuss the concepts in class. !! Class attendance is strongly encouraged and will be taken randomly. Also it will be used for extra credits. Course Advice !! This course has several components: !! Lecture: lecture, demos and Active learning !! Reading: study the text BEFORE lecture !! Homework: individual Web based problem solving !! Labs: group exploration of physical phenomena !! SI (Supplemental Instruction) session - to be named •! The pace is fast. It is important to keep up! #"Homework "! Homework problems are assigned and graded on the web through the commercial site MateringPHYSICS. "! Once you are registered, you will be able to download the assignments. "! The assignments are posted each Monday and are due by 11:pm on the Tuesday a week later. "! There are total of ~10 homework sets for this course. "! Pay attention to the instructions on the HW website about how HW is scored. "! To access MateringPHYSICS, you must register at http://www.masteringphysics.com/ "! Instructions are in the Student Access Kit. "! Your course ID is LEE2009 "! If you do not have the Student Access Kit which comes with a new textbook, you can purchase one on the MateringPHYSICS site. Please do this ASAP. "! This web site is not at TTU and you should give yourself plenty of time for submitting answers –sometimes the network can be slow or down. !&"'"("Exams !! There will be “3” in-class exams and a final exam (see Class Schedule for dates). !! The exams are closed book. You may bring one hand-written a 3” by 5” index card with formulae, etc. Telephones, pagers, PDAs, iPods, iPhone and other gizmos are not allowed. Calculators are needed. !! The final exam is comprehensive and is a common exam for all sections. !! There will be no make-up exams. )"Grades !! The lowest exam grade (not the final) will be dropped since there are no makeup exams. !! Lab & Homework 25%, each exam 25%, and the final will count 25% towards your final course grade. !! The grading scale is A=100-90%, B=89-80%, C=79-65% and D=64-50%, F=49 to 0. Exam Lab Exam Homework •! Lab, Homework 25% •! 2(out of 3) in class exams 50% •! Final Exam 25% Final Exam*"Help(s) !! Please do not wait until the last second to seek help. If you do not understand the material or feel that you are falling behind, seek help as soon as possible. !! Your instructor is available during office hours. If you cannot make it, call me or e-mail me. Dr. Sung-Won Lee, where: Sci 117, when: MWF 2:00-3:00 contact phone #: 742-3730 e-mail:: [email protected] !! TA:: Physics 1408 Lab (2 hr) /Recitation (1hr). Use their help. $+"Course Objectives You will learn: !! How to use Newton’s laws to solve problems with static and dynamic bodies. !! Use of conservation of energy and linear and angular momentum to solve problems. !! How to represent wave motion and solve problems about sound propagation. !! Learning Assessment: certain problems on the final exam will explicitly require facility with the course objectives and be used as learning assessment tools. $$"Lecture Notes!http://highenergy.phys.ttu.edu/~slee/1408/ $%"End of Administrative Details Go to Chapter 1$!"!! Fundamental Science !! concerned with the basic principles of the Universe !! foundation of other physical sciences !! Divided into 6 major areas !! Classical Mechanics !! Relativity !! Thermodynamics !! Electromagnetism !! Optics !! Quantum Mechanics $#"!! Mechanics and electromagnetism are basic to all other branches of classical physics !! Classical physics developed before 1900 !! Our study will start with Classical Mechanics !! Also called Newtonian Mechanics !! Includes Mechanics !!Major developments by Newton, and continuing through the latter part of the 19th century !! Thermodynamics !! Optics !! Electromagnetism !!All of these were not developed until the latter part of the 19th century $&"!! Began near the end of the 19th century !! Phenomena that could not be explained by classical physics !! Includes theories of relativity and quantum mechanics !! Still important in many disciplines !! Wide range of phenomena that can be explained with classical mechanics !! Many basic principles carry over into other phenomena !! Conservation Laws also apply directly to other areas $'"!! To find the limited number of fundamental laws that govern natural phenomena !! To use these laws to develop theories that can predict the results of future experiments !! Express the laws in the language of mathematics !! Should complement each other !! When a discrepancy occurs, theory may be modified !! Theory may apply to limited conditions !!Example: Newtonian Mechanics is confined to objects traveling slowing with respect to the speed of light !! Try to develop a more general theoryBrief History of Physics!!! ,-"$)./"012.3456"!! 718.92:;"<=>;;?0>="@10/>2?0;6","./1945"9A"B10/>2?0;"C>;1D"92"9C;14E>.?92;">2D"B1>;341B12.;"!! ,-"$*./"<12.3456"!!
