Required Textbook
We will be using Halliday, Resnick, and Walker, Fundamentals of Physics with bundled online
homework (WileyPLUS) and personal response systems (iclickers).
There are several UB bookstore options
For PHY107 alone
1. Halliday, 9e / VOLUME 1 with WileyPLUS SET ISBN 9780470944608
2. Halliday, 9e / VOLUME 1 with WileyPLUS & iClicker SET ISBN 9780470944615
For PHY107 and PHY108
3. Halliday, 9e / VOLUME 1 & 2 with WileyPLUS & iClicker SET ISBN 9780470944622
OR you can buy a used textbook, iclicker and the online homework access separately. Be aware
that your book should have Chapters 1-13 and 15.
Grading
The final grade will be computed as follows:
Recitation Quizzes 20%
1st Exam 20%
2nd Exam 20%
Final Exam 30%
Homework 10%
***Extra Credit***
In class quizzes (iclickers) 5%
assigned after the cutoffs determined from class ranking.
An Incomplete grade can only be requested by students who are at passing level before the final
exam and are unable to finish the course with legitimate reasons. No request will be accepted
after the final exam.
Any problem with grading, electronic or otherwise, should be dealt with as soon as
possible. Grades posted more than three weeks will not be discussed. Any inconsistencies
between exam grades and grades posted on UBLearns should be addressed to the course
secretary. See TA information.
Letter grades will be assigned based on your cumulative numerical grade according to your
ranking within your section as follows:
A: top 10% of the class
A- : the next 10 %
B+ : the next 10 %
B : the next 10 %
B- : the next 10%
C+ : the next 12 %
C : the next 12 %
C- : the next 12 %
D and F: the bottom 14 % of the class
The exam average will be given after each exam.
Communication
Because of the number of emails, those with questions already discussed in class will NOT be
answered. Emails concerning details of homework problems will not be answered, because it is
time consuming and not effective. Use office hours instead.
Discussion Board
All routine questions concerning the course should be posted to the UBlearns discussion board
where they can be answered by fellow students, TAs or instructors. We ensure that someone will
answer them within 24 hours. The discussion board is monitored by a TA.
Email
Technical questions regarding accessing the WileyPLUS website should be directed to
WileyPLUS technical support. Technical questions regarding using of iclickers should be
directed to iclicker technical support. Questions concerning grades must be made in person. No
grading questions will be considered by email.
The instructors will answer e-mail messages requiring personal attention at their discretion.
When sending e-mails, you should
1. use PHY107 as a part of the subject line, and
2. use your UB account.
Class Decorum
The main rule for class is consideration to all those within the class. No disruptive behavior
will be tolerated. NO TEXTING OR PHONE CALLS during class. LAPTOPS can only
have class notes on them. Technology misused during class will be confiscated during class
time and returned after class has ended.
Recitation T.A. and Office Hours
Check the course website on UBlearns.
Homework
The homework in PHY 107 is computer based and uses the WileyPLUS system. This system is
based on problems at the end of each chapter and is algorithmic; i.e. each student will get a
different set of numbers for the same problem. The students must purchase the WileyPLUS
package with the textbook or separately if you already have the textbook. The WileyPLUS
package contains the access code for each student as well as instructions on how to enroll. You
will be allowed four attempts on each problem. The system will let you know whether you got
the correct answer or not. If you have difficulty with a particular problem you are strongly
encouraged to go to the office hours of either your lecture instructor or your recitation TA and
get help so that you can attempt to submit your solution again. Twelve homework problems will
be assigned each week and all of them will be graded. The solutions to the homework problems
are available on WileyPLUS after the due date. The 3 lowest homework grades will be dropped
in calculating your homework grade, which is intended to cover missed homework for medical
and other extenuating reasons.
We expect that you will be working on the homework before the last minute and that by 9 pm
the day the homework is due you will have it nearly completed. If you have any technical
difficulties, contact Wiley immediately and forward Wiley’s reply to your lecturer. If we
receive this by 5 pm on the day the homework is due, Wednesday evening, then we can adjust
the deadlines. If we do not receive any confirmation from Wiley that the system is down by
Wednesday 5 pm EST, then the homework will be due in the usual way and your score will
reflect your actual work completed. If you have not waited until the last minute to work on you
homework, last minute outages should have little effect on your grade. Keep in mind each
homework problem contributes a maximum of 0.06% to your final grade.

emphasized
Midterm exams will be conducted in rooms of TBA.
Exam Policy
Exams will consist of problems similar to the worked example problems in the textbook and the
assigned homework problems. Exams will be closed book.
-Bring your student ID to the exam
-You should bring with you a pocket calculator to work out the answers to numerical
problems. Make sure that the battery is charged! Sharing of calculators will not be allowed.
-You will be given an equation sheet for each exam. We expect you to be able to solve the exam
problems with only the equation sheet. No other written or printed materials are allowed. The
equation sheets will be available on ublearns before the exam.
-All cell phones must be turned off and put away during the exam
Full credit on exams will be awarded for complete solutions including drawing a figure and
deriving necessary formulas, if appropriate, and for numerically accurate answers with
appropriate units and significant figures. Partial credit may be given for correct derivations if the
answer is numerically wrong due to arithmetic errors. No credit will be given for equations
written down at random or for numerical answers that are not supported by a reasonably
complete derivation.
The best way to prepare for the exams is to study the example problems and work out the
assigned homework problems each week. You should work as many additional problems from
the textbook as you can. This is the best way to insure your understanding of the material.
Regrading
Exams will be graded and returned to you and solutions will be posted. You may request
regrading of specific parts of your exam by returning it to your lecture instructor in class or
during office hours within one week after it has been returned to you. This request must be
accompanied by a typed note specifying which problem parts you wish regraded and why. The
note should be attached to the exam. Note that your grade may go up or down. It is therefore to
your advantage to be specific about the parts that you want regarded. Only one regrade request
will be allowed for each exam. Please do not write on your exam booklet or alter it in any
way. Exams will be randomly photocopied. Exams that have been tampered with or altered in
any way will not be regraded, and further appropriate disciplinary action may be taken. Exams
that have been tampered with or altered in any way will result in an automatic F for the
course. Graded exams will be photocopied at random.
Missed Exams
The only acceptable excuse for missing an exam is sickness at the time of the exam (certified by
a doctor) or a major emergency. The instructor should be informed before the end of the day of
the exam (call the Physics Main Office, 645-2017, if necessary). If there is a conflict with
another school related activity, it is decided by the instructor if it warrants a makeup exam.
If you maintain a passing average on the midterm exams and homework but miss the final exam
with a valid excuse, you may request an Incomplete (I) grade for the course. Incomplete work
must be made up when the course is offered again, and before the default deadline. A student
who is not maintaining a passing average cannot request an I grade.
Recitation Quizzes
Brief quizzes will be conducted each week by your recitation instructor. Quiz problems will be
similar to one of the homework problems. An equation sheet will be provided with the
quiz. There will be no makeup for quizzes which you miss. The 3 lowest quiz grades will be
dropped in calculating your quiz grades, which is intended to cover missed quizzes. Missed
quizzes on observed holidays will be given during the last two weeks of the semester.
In-Class Quizzes
There will be in-class quizzes with multiple-choice conceptual problems. The quizzes are
administered using the iclickers. You receive one point for simply taking the quiz and one point
for a correct answer. The quizzes are given randomly throughout the lectures and thus the quiz
grade is a measure of your attendance. This will also give students an opportunity to see how you
are doing before the exams.
If there is a hardware problem with your iclicker during class, you must notify the instructor
immediately. You will be given full attendance credit for that day. Notifying the instructor at the
end/beginning of class is not acceptable. You are expected to have a working iclicker at the next
class as a dead battery can immediately be fixed and the campus bookstore will swap a
nonfunctioning clicker for a new one.
HAVING THE ICLICKER WITH YOU IS A REQUIREMENT FOR THE CLASS. THERE
WILL BE NO MAKEUPS FOR IN-CLASS QUIZZES. NO EXCEPTIONS.
Resignation Dates
Last day to “drop” without financial liability: January 19, 2013
Last day to resign: March 29, 2013
If you are still registered in the course after March 19, 2013, you will receive an A-F letter grade.
The I grade is available only to those who are performing at a passing level but cannot complete
the course for a valid reason.
Home Page
This course has a home page at http://ublearns.buffalo.edu. Check out the home page for general
information, announcements, homework problem solutions, examination solutions, and
grades. Students who are not officially registered for the course should let the instructors know
so that they are allowed access to the course homepage.
Students with Disabilities
If you have a disability and require reasonable accommodations to enable you to participate in
this course, such as note takers, readers, or extended time on exams and assignments, please
contact the Office of Disability Services, 25 Capen Hall (745-2608), and also see your lecture
instructor during the first two weeks of class.
Academic Integrity
Students are responsible for abiding by the academic integrity policies of the University.
Academic dishonesty will be prosecuted to the fullest extent.
Restrictions on repeat enrollment
Please be advised that PHY107 and PHY108 have been designated as "limited enrollment"
courses, which means that the enrollment in these courses is limited by the number of student
positions available. Self-registration in these courses in the Fall and Spring semesters will be
limited to those students who are taking the course for the first time. Thus, repeat enrollment
may be difficult or impossible in the Fall and Spring semesters, and students who plan to repeat
the course for any reason should plan to register for the course in the Summer. Repeat enrollment
is defined as: a student who was previously enrolled in the course at UB, or who transferred an
equivalent course to UB, who received either a letter grade of 'A', 'B', 'C', 'D' or 'F' and qualified
values thereof (e.g. 'A-', 'D+'); or a grade of 'P', 'S', 'U', 'I', 'J', 'N', or 'R'. The only case in which a
student may self-register for a repeated course is when the student has taken an Administrative
Withdrawal for an entire previous semester, so that all the grades for that semester were
registered as 'W'.
