The Lecture:

If you have a question during the lecture you are permitted to interrupt me politely. Questions for the most part fall into two categories: (1) beneficial to the whole class and (2) those beneficial solely to the student asking. If you have a question that is beneficial to the whole class please interrupt me politely and ask it. However, if you are not sure or positively sure that the question will not benefit the whole or majority of your classmates then please see me after the lecture so that we can talk about your question. In general I will follow the spirit of the course material outline that I have provided below. During the lecture we may deviate from the outline by going ahead and falling behind. Nonetheless we will finish the course material. In general my lectures will not follow the book. My lectures are designed to give you another angle from which to approach the interpretation of physical principles that are in the text. I recommend that you read the appropriate chapter in the text before coming to class. And after the lecture read the chapter a second time. I will make use of the university's stockpile of demonstrations whenever I feel that such a visual aid will enhance the lecture. The exam will come when it is scheduled period.

Lecture Attendance:

I will expect everybody to be here every day of class. I am aware that life gets in the way of coming to class sometimes and when it does know that you are responsible for getting the notes from the lecture that you missed. It is extremely important for you to attend the lectures because I do not follow the text book's outline verbatim. I will often do problems that are similar or not found in your book as examples in class. You will also find that the exams that I write are based on the lectures. If you come to class and take good, clear notes. You should have no problem doing very well on the exams. Often, during lecture, I will announce important problems to study and important dates of up coming events.

Homework:

The assigned homework problems are due when they are scheduled to be turned in independent of whether we have covered the topic in lecture or not. I will not accept homework after the due date. No exceptions. In order to maintain a level of fairness with respect to homework grading procedures, we will use Mastering Physics (MP). This program will allow us to make sure that you receive credit for every problem in each set of homework that you complete. Homework submission will take place online at http://www.masteringphysics.com. Instructions for logging onto MP are located on a pamphlet included in your text and listed below for your convenience.

or by email: support@masteringphysics.com

________________________________________________________________________________

Along with the task of completing the online portion of your homework you are also required to turn in for a grade a hand written copy of your mastering physics homework solutions.

~The written version of your homework has nothing to do with the text book. You are to write out the problems that you solve in the mastering physics online program...

It works like this: Exam I covers chapters A-C the homework for chapters A-C that you completed using mastering physics is to be written in a neat pen and to be turned into me before Exam I . The homework solutions will not be graded twice, your T.A. will check to make sure that you have done what has been assigned. Your grade for this portion of the course will be graded according to three simple criteria: (1) the solution must be typed or hand written on a piece of paper, (2) the format will be the problem number, chapter and solution and (3) I receive it before the exam . The problem itself does not have to be written out. Simply indicate what problem you are providing a solution for and write out completely the solution. No credit will be given for written homework assignments that are scribbled on a mastering physics web page printout.

~Exam Scheduling:

Sample Exams Questions

lecture schedule and exam schedule

In order to accommodate your schedule I want to know what dates during this semester will be inconvenient for you to take an exam. By the end of the add/drop period I will schedule exams based on the inconvenient exam dates that you give me. Other situations that arise after I assign the exam dates will be subject to the make-up exam criteria below.

There will be several in class exams and a final exam that will be cumulative. Please rearrange your schedule so that you can take the final exam on the official date allocated by the University of Maryland . There will be no make-up exams unless absences are caused by illness, death, religious observances or participation in University activities at the request of University authorities. Any excuses must be formally documented. If a valid excuse for missing an exam is presented to me, a make-up exam will be scheduled that is completely different from the exam given to the class, in most cases, slightly more difficult. If the University closes or class in canceled on an exam day because of snow or any other reason, the exam will be given the next day of class. The spirit of the exam will reflect the physical principles that we discuss during lecture. The exams will not be cookie cutter, homework problems. So, do not expect to see problems that are exactly like the ones you did for homework. Problems that are covered in lecture are more likely to become exam problems. I will do my absolute best to make sure that there are no ambiguous problems on the exam. During the exam I will not answer any questions that have anything to do with the calculation of the problem. Please take a look at the seating chart for our lecture hall. On exam days the seating chart will be visible to remind you where you can and cannot sit for exams.

At the bottom of the first page of your exam you will see the declaration of honor. It reads as follows: “I pledge to my honor that I have not given nor received any unauthorized assistance on this examination.” You are not required to sign the honor pledge. You may sign it or not without penalty.

Exams will be copied by the physics department for your convenience in the event that an exam is lost. I will keep the original and the copy will be returned to you.

If you feel like your exam was graded too harshly then you may submit a separate typed or hand written paragraph outlining specifically an argument that favors your position. I will review your argument and make a decision in a reasonable amount of time.

All instances of suspected or direct cheating will be reported to the honor council. Cheating is an extremely serious matter and will not be taken lightly.

~Exam protocol:

0. Follow the seating chart provided by the Lecture Demonstration Department or the seat you are assigned for each exam.

1. No crib sheets or scrap paper.

2. Use any calculator you like.

3. Closed books.

4. Closed notes.

5. Closed classmates.

6. Only the top page of each sheet will be copied.(Side with a number at the bottom)

7. All of the equations that you need will be on the exam.

Your job is to know how to use the equations. Further, I will give you plenty of space to solve your problems and a specific space will be provided where you will write your final answer.

How to study for exams:

In your preparations for exams, study the problems that are discussed in lecture. When you study the problems presented during lecture I suggest that you redo the problems and then redo the problems two more times substituting different constant values into the equations. And more importantly reason through your result. For instance: Newtonian mechanics will allow for infinite energies and velocities. Einstein was able to bound velocities by the speed of light. If you were to obtain a velocity for an object that was greater than the speed of light using Newtonian mechanics. Immediately you should stop and check your calculation. This is an example of reasoning through your result. You may also extend your solutions criticism by asking the questions: Is the answer in the correct units? Does this make sense physically? Is the answer a vector or a scalar quantity? The chapter examples in the book are good for practice and grasping the mechanics of solving problems. Same goes for homework problems. However, they are not the driving force or particularly inspiring to me when I write exams. I will write exams that attempt to tie the physical concepts together. I will sometimes say “this is a good problem to study”. Listen to me in class I will give you all kinds of hints as to what I am considering to put on the exam. Reference other physics text books and look up specific subjects online.

Practice Problems

Co-requisite Physics 261, Lab

• The lab course 261 is taught by Professor Boyd in Room 3219 (Physics Building). 
• The lab will count for 25% of the course grade.  Professor Boyd will give me the grade that you have earned in his course, and I will use it to calculate your final grade for Physics 260.
• The final grade you receive in Physics 260 will also be the grade you receive for Physics 261.
• In accordance with the rules set forth by the University of Maryland if you receive a failing grade for Physics 261 you will also fail Physics 260.
• If you have taken this course one time before and you have a good grade in your lab section then the grade for your lab work can be imported into this semester. You will have to register for a dummy lab course that is reserved for students who intend to import there lab grade from the previous semester.

Mastering Physics online Homework=10%

Written HW=10%

Average of Regular Exams=40%

Laboratory = 25%

Final exam=15%.
