Texts: PHYSICS, 6th Edition, Douglas Giancoli, and Physlet Physics, Christian and Belloni


Course Objectives: This course is the second half of a two-semester introduction to physics.We will cover much of chapters 16 through 31 this semester.Topics will include electricity and magnetism, electromagnetic waves, optics, relativity, and atomic and nuclear physics. The text is encyclopedic in coverage, so we will choose to omit a number of sections and two chapters.We may use the results of the omitted sections, but we will not do the detailed analyses involved. We will also not cover every assigned section in class.Many of the more straightforward sections will be left to your own reading, while class time will be used to discuss concepts, develop understanding, do demonstrations, look at computer simulations, and work problems.We will meet as scheduled below.The chapter assignment for each day indicates where we will probably be at that time.Your reading of the text material for the first time before the lecture is a necessary requirement for the way we will approach the material.Learning in this class is for active learners, those who participate actively in their learning and donít just expect to be fed all the material and all the answers. Reading the text material a number of times is part of that participation.


Course Requirements:


Attendance: My attendance rule in this class follows the College's 25% rule: missing 25% of the classes results in an F in the course.Attendance is required at reviews and for lab.You are responsible for the material presented in class each day and for any announcements that are made; you should check with your peers for any information that you miss.You should mark the roll on the bulletin board each day you are present. If you are sick or have another emergency before a laboratory session or a review, please email me beforehand so we can make accommodations.


Honor Code: One of the best things about teaching at Davidson College is the Honor Code.You each have agreed to adhere to that code in everything you do and to enjoy the privileges it provides.If there are any questions about how the honor code applies to a given assignment, please ask me.Rather than write the full pledge (On my honor I have neither given nor received unauthorized information regarding this work, I have followed and will continue to observe all regulations regarding it, and I am unaware of any violation of the Honor Code by others.) out for each assignment, I will assume that the word PLEDGED and your signature on each assignment means that you have subscribed to the pledge on that assignment.


ADA: If you have a diagnosed learning or other disability such that you are allowed accommodations for reviews, assignments or the final exam, please make sure that you contact the Dean of Students office immediately.I must receive notification from the Dean of Students office regarding your accommodation for this course before the assignment is due or the review is to be taken.Please attend to this as soon as possible.


Electronic gadget and email policy:Remember that your gadgets, including cell phones and laptops, affect everyone in the class.Cell phones are to be turned off in class and lab.I do not allow the use of laptops during class, unless you clear it with me beforehand to take class notes.


In this course, my methods of contact with you outside of class are through my office hours and my sending and response to emails.I have office hours that are set based on your class schedules and that allow you a lot of contact with me and other members of the class who might be there at the same time.Please avail yourselves of them; they are the best way to receive help in this course.I never do long replies by email.If you have a short question, I will respond within 24 hours.For longer questions, office hours are the way to get help.


Homework: Questions and problems for each chapter are shown below in a suggested work schedule. These are subject to change, so the website is the authoritative site for the homework assignments.The homework is to be worked and handed in at the beginning of the period on the due date that will be assigned in class and placed on the website. Other problems may be assigned from time to time; these extra problems will be announced in class. Problems are denoted below without an asterisk if they are to be done only by you, with any help that I can offer during office hours.Problems with an asterisk can be done with discussion among class members (including me).This discussion can be about homework strategies and clarification and interpretation of problems and is strongly encouraged.The tutors in the Math and Science center can be used in this same way.The solution that you write down on your paper must, however, be your own.Copying a tutorís work or another studentís work from this class or previous classes, using printed solution manuals, or using solutions that are posted online is an honor code violation.The work that you write down on your paper must ultimately be your own.Problems are to be pledged as having been done according to the above requirements.The word PLEDGED with your name, the date, and your signature on the outside of your vertically folded homework paper signifies your compliance with these requirements.I do not accept late homework except in case of emergency.I also do not grade unpledged papers and do not give full credit for unsupported answers (if the answer is NO, for example, I want a reason).


Quizzes: There will be brief quizzes, unannounced, at the beginning of some classes to prod you about the task of keeping up with your coursework.These quizzes last only a few minutes and are designed to be taken during the class when they are given.They are designed as a learning tool - an integral part of the class discussion for that class Ė not as an assessment.Thus, I do not give make-up quizzes, regardless of the reason for missing class, since you could not participate in the class discussion that follows.Quizzes count for less than 1% of your final grade and are included in the homework portion of that grade.


Reviews: Our reviews are closed book and will be comprised of questions and problems similar to the homework and those from class, as well as definitions, explanations of concepts and phenomena, and interpretations of physical principles.


Laboratory: Your laboratory sessions will meet on Wednesday and Thursday with Professor Gfroerer.The lab schedule is attached as the last page of this syllabus.Labs are scheduled to be three hours long.The Thursday lab session is listed as longer by the Registrar because of the way class periods arrange themselves under the new Tuesday-Thursday schedule which allows for the open hour.Specifics concerning lab will be given in the first several class periods and in the individual lab meetings.


Final Exam: Your final exam will be a closed-book, self-scheduled one and will be held during the regular exam period.The exam is comprehensive and will also include material covered between the final review and the last day of class.
