Tentative Schedule (Subject to change as we go.)
We will begin with chapter 15 and cover through the end of the book, chapter 30. Some chapters will be covered in more depth than others, and some sections will be omitted. Details and test dates may change somewhat. Of course the final exam date and time is written in stone by the College.

Syllabus Fine Print

General

Text: Essentials of College Physics by Serway and Vuille. We will start with chapter 15 and cover to the end of the book, Chapter 30.

Physics is a field in which we attempt to describe, explain and predict how things happen. A law in physics is a concise summary of a broad collection of observations. The primary tools in physics are observation and mathematics. The latter allows us to make simple yet concise statements of physical law. Our simple mathematical statements of law become a vehicle for precisely predicting the behavior of the physical world we live in. It is also important to be able to use words to describe and predict the behavior of systems.

If you have a question, please ask it. If you have a comment, please make it. Even an anonymous note under my door or in my mailbox is fine. Communication is the essence of the classroom experience. I am pleased to see you any time you can find me. I encourage you to use email, although it is tough to give detailed help with problems via email.

Assumed Knowledge
You should be comfortable with math through algebra and trigonometry, on graphs and their interpretation, and physics at a level consistent with physics 101. Yes, we will still use the material from the first half of the book. Math is a skill needed in the modern world outside of physics.

Preparation
I expect you to have studied the relevant material for each day, such that you could answer simple questions about the material before it is presented in class. Assume that I may give you a short quiz at any time to help motivate you to be prepared for class. The best advice I can give you is come to every class, participate, take good notes, read the book, do the problems and keep up. The most common, and perhaps the deadliest habit is to postpone your assault of the material.

Bring your calculator every day!

Attendance
Attendance and participation is critical to the learning process and an integral part of this course. In general, I believe that absence is its own punishment, that is, you miss things you can't possibly get by going over a classmate's notes. You are responsible for material covered that day. Contact one of your classmates for the notes. Failure to attend class on the day an assignment is assigned or due does not mean that you may turn in a late assignment without penalty. There are certain aspects of the course for which the information can be obtained only in class, thus, a student who misses class will miss material they will need on quizzes and tests. There will be no makeup quizzes. If you have a medical or personal issue please contact the Student Affairs Office to get it documented. After I get notified by the Student Affairs Office I will judge whether you get an excused miss or a zero for the late or missed material.

To document an absence for any class

Each student who attends class is expected to participate in a positive manner. This means being on time (so as not to disturb the learning of others) and making positive contributions to the learning environment. Students who disturb others will be asked to leave.

I keep daily attendance sheets which you will initial in class. These sheets are used to identify problem attendance patterns, and may be used to help me make decisions in borderline cases when I am assigning final grades.


Goals

-To increase understanding of natural laws by surveying the major areas of physics
-To develop physical curiosity
-To enhance problem solving and critical thinking skills
-To enhance investigative and observational skills
-To develop logical qualitative and quantitative reasoning
-To develop communication skills
-To connect physical concepts, principals, and laws to global and societal issues

Objectives

Students will be able to:
-apply conservation laws
-describe the nature of electromagnetic phenomena
-apply elementary physical and geometrical optics principles
-describe the nature of the universe on the atomic and nuclear scale
-describe the postulates of special relativity and their fundamental consequences
-provide a description of how to solve a problem, justifying their choices
-apply physical principles to novel situations
-provide different representations for a problem (verbal, graphical, vectors, diagrams, or equations)
-describe the role of physics and physicists in history
-Solve word problems

Responsibility
You have responsibilities to yourselves, your classmates and me. One responsibility is to be to class every day and on time. Another responsibility is to keep up with the pace of the class. Do not think it is my responsibility to teach you. IT IS NOT. It is my job to create an environment and situations in which you can teach yourself. This course is organized by the above goals and objectives in order to achieve this end. The goal of education is to empower the individual student to be self-taught. I can't really do this for you, but I can help a lot.

Homework & Quizzes
Homework will be assigned, but not collected. I encourage you to attack the homework promptly as we cover the material. Frequent in-class quizzes will rely heavily on homework proficiency and material presented in class. If you keep up on your reading and homework assignments and are attentive in class you should be OK on quizzes. Expect a quiz every Friday, but I can give one any time. Make-up quizzes are not given. I will throw out the lowest quiz score.

Tests
We will have four mid-term tests plus the final exam. My tests tend to require you to solve problems, draw or interpret graphs, make sketches, and provide explanations. I generally do not have multiple choice or true/false questions, although they are somewhat more likely on the final exam. If you question your score on an exam you must bring it to my attention within 24 hours after the graded exams were handed out in class.

Calculators may be prohibited for use on quizzes and exams without notice. This is not a cause for panic. The math will be simpler to accommodate the lack of a calculator. It is also possible that you may be provided with another calculator at any time.

FINAL EXAM: Wednesday, 30 April, 8-11 am

Grades
I will give you specific letter grade on each exam, so you should always have a pretty good idea where you stand. I encourage you to see me at any time for my assessment of your work.
