Physics 101 page 1/4 Physics 101, Physics for Scientists and Engineers Fall 2012 - Course Description Instructor: Dr. Derrick Kiley Office: SCI-222H; Office Phone (323) 953-4000 EXT 1922 E-mail Address: [email protected] Course Webpage: http://faculty.ucmerced.edu/dkiley/physics101.html This will change, soon. Class meets: 12:10 – 4:45 (with a break from 2:10 - 2:45), Mondays and Wednesdays in SCI-208. Office hours: 9:00 – 10:30 a.m., Mondays and Wednesdays in SCI-222H. Prerequisites: Physics 11 or successful completion of High School Physics, Math 261 or an appropriate score on a math placement test. Textbook: All texts are available in the college bookstore. Physics for Scientists and Engineers, Eighth Edition, by Serway and Jewett (earlier editions are acceptable). There is also a required lab manual, Physics 101 Lab Manual. Finally, there is an optional study guide for the course, Student Solution Manual and Study Guide for Serway and Jewett’s Physics for Scientists and Engineers. Topics and Outlook: This course will introduce the basic ideas of Newtonian Mechanics. This is a very large and interesting area of physics, and after the completion of this course you will understand the application of many areas of physics. We will begin with a thorough discussion of motion, including motion under the influence of gravity. We will extend our analysis from simple motion in a straight line to motion along more directions, for example by considering the trajectory of a projectile like a cannonball. After this, we will ask, “where does this motion come from?” “What makes things move?” The answer to these questions is found in Newton’s laws of motion. These three laws really encompass all the main ideas of motion - everything else is application, and can be obtained from these laws, as we’ll see. Following our discussion of Newton, we will then discuss one of the most important concepts in all of physics - the conservations laws. We will see that there are some quantities that, no matter how we twist and turn our system, these quantities always stay the same. Examples of these quantities include energy, momentum, and angular momentum. Using these quantities makes solving problems considerably easier. Next, we will consider fluids such as liquids flowing through pipes and the air pressure at various heights, ending with a basic discussion of elasticity. Next, we will discuss gravity in much more detail, discussing how planets orbit the Sun as well as some very interesting applications of gravity, including black holes. We follow gravity by a discussion of systems which are vibrating, which turns out to be an extremely important area of physics because, as we’ll discuss, many systems (such as a pendulum, electrical circuits, and even electrons in an atom) can be described as a vibrating system. Depending on the timing of the topics, an occasional special lecture on an interesting topic will be presented. 1 Physics 101 page 2/4 - Tentative Syllabus All Dates Approximate!

Because physics builds upon itself, missing one lecture can affect your understanding of all that follow. If you are absent for more than 9 consecutive hours during the first two weeks, then you may be dropped from the course. 2 Physics 101 page 3/4 Grading: The grading will be based on the final (25%), 12 quizzes (50% total), and the discussion/lab sessions (25% total). - Tentative Grading Scale A 85% – 100% B 75% – 84% C 65% – 74% D 55% – 64% F Below 54% Quizzes There will be 12 quizzes, each held during the lab/discussion sessions on Mondays (except for Wednesday, September 5th and November 14, since those Mondays are holidays). We will do our best to give plenty of partial credit, so always attempt the problems, even if you don’t finish them! Final: The final exam is scheduled for Wednesday, December 12, from 12:00 – 2:00, and will be comprehensive. The quizzes and final exam are closed book. If some complicated formulas are needed (such as a nasty integral) they will be provided, as will any required numerical values, etc. You may use calculators. You should bring your student ID along so that your identity may be verified, if necessary. Discussion/Lab Sessions Part of the course includes a discussion/laboratory (DL) session. These sessions meet twice a week and will contribute a large amount to the course, so it is important that you attend these. During certain sessions you will perform experiments, while during others you will work problems. These DL meetings contribute 25% to your grade, and are manditory! - Tentative Lab Schedule Topic Date There will be five labs each Lab 1 Wednesday, August 29 meeting during your reguLab 2 Wednesday, September 12 larly scheduled DL time. Lab 3 Wednesday, September 26 Lab 4 Wednesday, October 31 Lab 5 Monday, November 19 Important! Drop Date Information The deadline to drop without a W is the last day of Week 2 (of the semester), which is Sunday, September 9th for Fall 2012. If you must drop a course, drop before the specified deadline for dropping a class without a grade of ”W.” Dropping after Week 2 will result in a W on your transcript. Effective July 1, 2012 students will only have 3 attempts to pass a class. If a student gets a ”W” or grade of ”D”, ”F”, I, or ”NP” in a class, that will count as an attempt. A students past record of course attempts district wide will also be considered. Therefore, before the end of Week 2 you should carefully consider if you can reasonably manage this course with the other factors in your life (e.g. work, family, course load). If you think you will not be able to complete this course with a C or better, drop by Sunday, September 9th. If you have any questions, please don’t hesitate to talk to me. You may also see a counselor in the Counseling Center in AD 108. 3 Physics 101 page 4/4 Learning Objectives for Physics 101 Upon completion of Physics 101, you should understand : • Simple motion through space. • The concept of vectors. • Newton’s three laws of motion. • That the net force acting on an object is the sum of the individual forces. • That energy can change forms between kinetic and potential. • That several quantities do not change in time, including energy, as well as linear and angular momentum. • That the gravitational force on an object is given by Newton’s law of gravity. • That any system slightly displaced from stable equilibrium will undergo simple harmonic motion.
