Course Webpage: http://staffwww.fullcoll.edu/bshotwell/phys223 Course Schedule: Lecture: Tuesdays 1:30-4:40pm P-417 Section ID: 11292 Lab: Thursdays 1:30-4:40pm P-417 Textbook: There are two required textbooks for this course: Sears and Zemansky's University Physics, 11 th 14 th Edition by Young / Freedman. Any edition (11 th 14 th ) is fine for this class. You will need MasteringPhysics, which by itself costs $66. If you buy the newest-edition textbook at the bookstore, access to MasteringPhysics is included. Special Relativity: For the Enthusiastic Beginner, 1 st Edition by Morin. Our main textbook doesn't do justice to relativity (1 chapter), so we'll spend 2-3 weeks on it and use this. This part of the course requires a lot of reading but it's relatively (har har) fun. Course Information: Physics 223 is the third of a three-semester introductory physics sequence intended for engineering and physical-science majors. This semester consists of a standard sequence of (the rest of physics not covered in mechanics or E&M), including waves, thermodynamics, relativity, optics, and quantum mechanics. This is the order in which we'll cover these five units. Student Learning Outcomes: Upon successful completion of PHYS 223, students will be able to: Explain qualitative outcomes of various modern physics scenarios by applying deductive reasoning with the appropriate laws and principles of physics. Determine quantitative outcomes of various modern physics scenarios by applying algebra, trigonometry, geometry, and calculus with the appropriate laws and principles of physics. Investigate various modern physics scenarios experimentally and explain the results in terms of the appropriate laws and principles of physics.
Organization of Class (Roughly): Lecture days (any day without an exam/lab) will generally have the following schedule: 1 hour, 45 minutes: Answer questions; Lecture w/ examples and in-class participation. 15 minutes: break. 1 hour, 10 minutes: Group-work going over conceptual and problem-solving examples (4-5 students each group); work on homework. Lab days will have the following schedule: 10 minutes: Lab quiz (on same sheet as prelab; turn in both @ end of quiz). 1 hour: Lecture w/ examples and in-class participation. 15 minutes: break. 1 hour, 45 minutes: Lab (with a 5 minute introduction at the beginning). On five days we will have an exam. For those days, the schedule is: (Exams 1, 2, and 4): 2 hours: Exam; 10 minute break; 1 hour lecture. (Exams 3 and 5): 3 hours, 10 minutes: Exam (and you may leave when you've finished). Grading Policy: Your final course grade will be determined according to the following: 16% Homework (MasteringPhysics problems most weeks, except those involving relativity). 20% Labs (2/3 from lab writeups / participation and 1/3 from lab quiz / prelab). 4% In-Class Responses / Participation Grade. 40% Five Midterm Exams (Five exams / 300 points: 50+50+75+50+75, see course schedule). 20% Final Exam (all MC questions). More information about each component can be found in the following sections. Final grades will not be determined until the end of the quarter. The A/B cutoff is 84% (overall % for the course), the B/C cutoff is 72%, and the C / :( cutoff is 60%. Homework: Most of your homework grade (12%) will come from MasteringPhysics (MP) assignments due on Tuesdays before class. The other 4% will come from ~3 relativity problem sets. Read the books. The books makes sense and are reasonably concise. There is a lot to cover this semester, but for the most part it's a lot of little things that are easy to digest. Discussion Board: We will use Piazza an online course discussion board where you can ask / answer questions about the course material (including homework). If you send me an email about a specific problem, I will redirect you to Piazza. There are two clear benefits: (1) Everyone can see questions / responses, which helps if you have the same question; and (2) students can help one another in case I am not available at 3am.

In-Class Response System / Participation Grade: Part of lectures will consist of (mostly conceptual) questions given to the class, where you can discuss the problems with other students and respond via a paper-adapted pre-technology system (lifting up pieces of paper with A E on them). So long as you're present (not late / don't disappear for 30+ minutes during the class) and participating, you should be able to get the full 4% participation grade easily. Labs: When a lab is scheduled, you need to bring three things: the writeup to the previous lab, the completed prelab (in your lab notebook), and a printout of the lab to perform that day (the lab to print will be posted on the course website). Each lab will contain a small quiz at the beginning of the lab to make sure you have read the lab. Labs are worth 10-15 points each: 5-10 points for the lab writeup / participation (5 if no formal write-up, 10 if a writeup is required), 2 points for the prelab question(s), and 3 points for the in-lab quiz. In-lab quizzes test to make sure that you have read the upcoming lab. Exams: There will be five total exams; see the course schedule below for the dates and content of the exams. There will not be any makeup tests. An excused absence (this is very rare! only if you have a letter from a doctor) for an exam will mean that your final exam will be worth more. Three of the midterm exams will be a combination multiple choice questions and 1-2 freeresponse questions. I will provide practice tests throughout the quarter so that you'll have an idea of what the tests will be like. The exams on relativity and quantum mechanics (worth a little more than the others) will not have any multiple-choice questions and will instead have only free-response questions. You are allowed ONE PAGE (8.5 x 11 both sides) of handwritten notes for each exam. Since you are allowed notes during the tests, the instructor does not need to write anything on the board during the tests, and so any constants you need to look up when answering the homework problems should probably be in your notes (for example: c = 3.00 x 10 8 m/s, trigonometric identities, etc.). Graphing calculators are allowed, but nothing fancier than a TI-89 (e.g., no laptops or cell phones). If you are uncertain about your calculator, then you should check with the instructor before the first test to ensure it is allowed. See the next page ( Scantrons / Test Instructions ) for more details on what you are required to bring to the exams, and for directions to follow in filling out your scantron. Academic Dishonesty: Please read the College Policies section of the Fullerton College General Catalog. These rules will be enforced. For all exams and labs, cheating includes, but is not limited to: submitting another person's work as your own, collaborating with another person during an exam, copying from any person/source, and using any unauthorized materials or aids during exams. Any instance of cheating will result in a zero for that quiz, homework, or exam. Two instances of cheating will be interpreted as a premeditated ongoing scheme and possibly result in an F in the course.
Scantrons / Test Instructions: Follow these directions very carefully to avoid being penalized: 1. On the first day of class, you will be given a scantron; on the form will be a 3-digit number. This Test Number / Exam Code is your identity for the course it is the only way for me to post grades online anonymously. Results to exams, labs, etc. will be posted on the course webpage by this exam code number. Remember this number for the rest of the course put it in your phone, tattoo it to your arm, whatever. 2. You will have to provide your own scantron form for exams 1, 2, 4, and the final. It is scantron form 882-E. These are green and sold at the Fullerton College bookstore. You must also bring a #2 pencil to the exams scantrons filled out in pen will not be accepted. Here's a sample of what your scantron should look like when you turn it in: Please email me if you have any questions related to scantrons, test code numbers, exam grades / answers to tests, etc.
