I. Purpose of this course

Physics 407 is a calculus based study of the fundamental principles of classical mechanics, which govern the motion of objects.  In the summer, it is an  intensive course that finishes in 8 weeks, with 7 lecture hours and one lab each week.

II. Registration

You must be registered for both PHYS407 and the lab section PHYS407L.  Please go to the Physics Department Office (Room 105 DeMeritt Hall) to add or drop the course (forms may be obtained at the Registrar's Office).

III. Prerequisites

You must have a basic understanding of high school algebra, geometry and trigonometry, and be registered for Calculus I (MATH 425) (unless you have already taken and passed MATH 425 or equivalent).

IV. Textbook

You must have a copy of the textbook: Fundamentals of Physics, 7th ed., Halliday/Resnick/Walker (John Wiley 2005).  It is very important that you read the chapter(s) before you come to the lecture that covers that chapter(s). Please refer to the schedule below (subject to change) for such reading assignments. You should bring your textbook to the Lectures.

Also on reserve in the Physics Library: V. Lectures

The purpose of the lectures is to give you a broad overview of the material. You are expected to have reviewed beforehand the lecture material. During lectures I will go over the key concepts, do examples, and illustrate the principles with demonstrations when possible. Some lecture notes will be available for download via the course home page (http://plasma4.sr.unh.edu/ng/phys407/phys407.html), by clicking at the dates of the lectures in the schedule. These notes are to remind you about some topics covered in the lectures, not to replace the lectures themselves or the textbooks

VI. Homework

Doing homework is key to doing well in this class.  Since this is an intensive course, there will be two homework assignments each week, except only one for the first week, the week of July 4th, and the last week, which means 13 assignments in total. Assignments are to be done through WebAssign (https://www.webassign.net/login.html) and will be graded automatically and instantly so that you can get the feedback at once.  You DON'T need to buy the WebAssign enrollment card to be able to use WebAssign since the department has already paid for it. The deadlines for submission of assignments through WebAssign are 11:59 PM on Monday or Thursday (except for the last week), unless otherwise announced.  However, you should work on your homework as early as possible before a deadline so that you can have time to ask for help if you encounter difficulties in solving these problems.  To emphasize the importance of doing homework, homework grade will count towards 25% of the total grade of the course, excluding the assignment with the lowest grade.   A separate sheet on how to use WebAssign is provided along with this handout.

VII. In Class Concept Questions

Short Concept Questions will be included in almost every lecture. You need a “Remote Pad” (“Star Trek Communicator”, available at the bookstore) to participate in the interactive concept questions during class. You need to register the device for this class with the Enrollment Code and Serial # of your “Pad” and the Physics 407 Class Key (Q9868W742) on the e-Instruction website (www.einstruction.com). Follow the instructions on the website after you log on.  For more instruction, download this form via http://plasma4.sr.unh.edu/ng/phys407/cpsregistration.pdf

Please bring your “Star Trek Communicator” (Remote Pad) with you every class. You receive credit every time you use it in the classroom to answer the Concept Questions and will be instantly graded through e-Instruction (count towards 5% of the final grade).  You will get full credit for attempting to do ALL the questions, whether your answers are correct or not.

Possession of two or more clickers is a violation of Academic Honesty Policy and would be treated as such. Note that a student who gives his/her own clicker to another classmate to use in class is also in violation of the Academic Honesty Policy.

VIII. In Class Group Problems

On Mondays or Thursdays, when there is no quiz, you will work in groups of two or three on some written problems. The focus of these group problems is problem-solving.  You will need to discuss the problems within each group, but each student is to write down the answers on his/her own problem sheet.  I will go around to provide help on the problems.  The group problems will be graded and count towards 5% of the final grade.

IX. Examinations

There will be 3 closed book one-hour quizzes and 1 two-hour final exam. Calculators and one page (5 pages for the final) of your own handwritten notes are allowed for each quiz.  THERE WILL BE NO MAKE-UP TESTS. Quizzes count towards 30% of the total grade. The final exam counts towards 25% of the total grade. You must not miss the quizzes and the Final Exam (except for documented illness or family emergency ). The following are the dates for the exams:

Date:

Time:

Room:

Quiz 1
Thu, June 23       
11:30AM - 12:30AM DeMeritt 152
Quiz 2
Thu, July 7
11:30AM - 12:30AM DeMeritt 152
Quiz 3
Mon, July 25
11:30AM - 12:30AM DeMeritt 152

Final Exam
Thu, August 4

10:10AM - 12:30AM DeMeritt 152

Approximately half of the three one-hour quizzes and the 2-hour final exam will consist of questions qualitatively similar to those you have seen in homework/concept questions/group problems.  Moreover, some questions in the finally exam will be similar to those you have seen in the three quizzes.  Thus, it is important to keep a record of all your course works and review them  before the tests.

X. The Laboratory

The purpose of the labs is multi-fold. First, you gain hands-on experience with the physical principles that we discuss in lecture. Second, you begin to experience how science is done, including using a theory to design an experiment, taking measurements, and understanding sources of error. Third, in writing the lab reports, you will gain experience in technical writing. Additional instruction fro writing lab reports can be downloaded from: http://plasma4.sr.unh.edu/ng/phys407/Lab.pdf.  The Lab Instructor will spend a few minutes at the beginning lecturing on the lab itself or on the relevant physics concepts.

The labs will meet in DeMeritt 101 from 12:10 PM to 2:00 PM on Wednesdays . Everyone should attend their first scheduled lab during week 1 (on June 15).  Lab instruction manuals may be picked up at the first lab meeting.

You must hand in all the laboratory write-ups to pass the course.  For most labs, you will need to do pre-lab questions before you come in to do the lab.  Your Lab Instructor will let you know the due dates of the lab reports and will give give you more information on how lab reports are graded. If you miss a lab in a particular week, you must make it up. Please contact the Lab Instructor as soon as possible to arrange for a make-up lab. The lab grade counts towards 10% of the total grade of the course.  However, you are required to do all the labs in order to pass the course.

XI. Grading

The final grade will be composed of:

3 one-hour quizzes: 30 % Every quiz counts
Final exam: 25 % Mandatory!
Laboratory: 10 % ALL Labs required for pass!
Homework (WebAssign) 25 % Lowest homework grade is dropped
In Class Concept Questions
5 %
Three lowest grades are dropped
In Class Group Problems
5 %
Lowest grade is dropped
Total: 100 %

Normally, getting 50% of the total points will get a grade C, subject to adjustment. We strongly suggest that you keep all of your graded work at least until the end of the semester. On occasion, a grade is not entered correctly, and the only way we can correct it is if you have the graded work for us to see.

XII. Getting Help

My office hours are 1:30-2:30 PM on Monday and Thursday,  at 245B Morse Hall. These are hours set aside especially to help you - do not feel like you are imposing or cheating by coming in. If you have problems that need immediate attention, please come to see me any time, send me an e-mail or give me a call.

Occasionally a student may have compelling non-academic reasons for not being able to complete work on time (for example, illness, death in the family). If you find yourself in such a situation, please come talk to me as soon as you can (or E-mail or call if you are at a distance) so we can determine what course of action is best to help you finish the required work.

The textbook has a web site: http://www.wiley.com/college/halliday (follow link to Student Companion Site).  It has many resources that provide additional help.  We also have this home page of the course: course: http://plasma4.sr.unh.edu/ng/phys407/phys407.html. I may put additional materials that may be helpful to you later on. So, please come back often, especially to check any changes in the schedule.
