Office Hours: at Pai 2.48,
Fridays, 3 to 3:45 PM.
The Fall 2016 unique number is 55530; the class meets from 2 to 3 MWF in Pai 2.48. Attendance is REQUIRED in class, and the roll will be checked each day using iClickers. The TA is Kha X. Tran. He will hold regular office hours and a weekly session to provide help and advice on homework, as well as sample problems for study. Office hours: Friday, 4pm to 5pm in RLM 2.414. Discussion and help session: 11 am to noon every Thursday, JES A203A, the first room right across from J2 dining hall in Jester Center. Important! If you need immediate personal help with the homework and are on campus, the Coaching Tables by the elevators on the 5th level of RLM Hall (West of the elevators) are manned by up to three different coaches at most times, weekdays, from about 9 AM to 7 PM.
Text: COLLEGE PHYSICS (9th ed or
later) by Serway and Vuille, Vol. 1 (Brooks-Cole,
2012 or later ). Earlier editions will also
work. Electronic editions exist. Also
publishers like Cengage have produced compact
paperback texts that have no homework problems at
the end of each chapter, since no such problems
are assigned in courses that use Quest. Look
carefully at the course first day handout and
syllabus; there are chapters in the text that are
out of logical sequence. Following all earlier
instructors we will cover the chapters in a
logical sequence, so 13 and 14 are covered before
10 through 12. This course and text cover basic
physics using algebra and trig but not
calculus. 317K and L cover the same material
using calculus. You should probably not be
taking this course if you are majoring in science
or engineering. Science majors take Phy 301,
315, 316 while engineers take Phy 303K and L.
The homework for this course is
handled by the Quest on-line homework service.
Homework assignments are turned in by you on-line
from your web-browser, logging-in with your UT-EID
An FAQ page is available
here. Complete homework and quiz
solutions are available on Quest within 15 minutes
or half an hour after the deadline. Quest requires a
$30 charge per student for its use, which goes
toward the maintenance and operation of the
resource. After the 12th day of class, when you log
into Quest you will be asked to pay via credit card
on a secure payment site. You have the option to
wait up to 30 days to pay while still continuing to
use Quest for your assignments. If you are taking
more than one course using Quest, you will not be
charged more than $60/semester. For payment
questions, email Quest
SO FAR: In a course like 302K, the homework average is almost always near 80%. To insure you do well in the class, strive to make a grade far, far better than 75% on each assignment. Since Quiz 2, the average number of students coming to class has been 70, out of 102 enrolled students, and only about 80 are turning in homework. A quick scan of overall course grades on Quest shows about 25 students out of 102 currently making D or F. Class "notes": Chapter 2, Chapter 3, Chapter 4, Chapter 5, Chapter 6, Chapter 7 (first half), Chapter 8, Gravity (last half of 7), Chapter 9, Chapter 13, Chapter 14, Chapter 10, Chapter 11, Chapter 12.
RUNNING TABLE OF HOMEWORK DUE DATES AND TIMES:
Here is a way to get extra credit!
Here is the Golden Rule of physics problem-solving. Ignore it at your extreme peril.
Important: the Laboratory Course 102M is a REQUIRED CO-REQUISITE for 302K. It is your responsibility to register for and take the lab, simultaneously with 302K, unless you have already taken and passed it in a prevous semester. All lab sessions probably start the week of September 1, but make sure by checking with your lab instructor.
COACHES AND TUTORS: Coaches are present at tables by the elevators on the 5th level of RLM, at various times between 9 AM and 5 PM weekdays. Coaches are there to give you hints on homework problems, and mini-lectures on key concepts in physics. You can obtain a physics graduate student tutor by contacting the undergraduate secretary, whose office is around the corner from the coaching tables on the 5th level. If you are experiencing any difficulties in doing the homework you probably need a tutor, and you would need to work with him or her beginning as early as possible in the semester. Note that free tutoring is available here. And free study group tutoring is available here.
