Welcome to PHY2053
First part of introductory physics not involving calculus
The lectures will be given by myself and Prof. Ho Bun Chan.
Website: from physics department
Teach this class twice on T Th, 2nd and 3rd period, one after the
other
Office is on second floor

Text book (note that the instructor textbook has a color
hardcover, student versions looks different)

bookstore
Need for HW
~ $35 on its own

Blue book:
Another optional item
Society of Physics Students assembled a course packet of previous
exams and they wrote the solutions.
They sell it for $17 at target copy.
Prof. Chan and I do not get any of this money. It was the SPS who
solved the exam problems.
You can get it at the Target copy at University avenue, not the one

HW to help you practice, very important

Everybody needs to use this password the first time he/she
logs on.
After you have logged on,
Enter the code that comes with the book, or purchase on line.
System lets you change password
You have 13 days of free access to webassign.
Can keep using this password.
Must enter the code before the deadline. After the deadline,
this universal password will no longer work.
Will not be able to access the homework page
First assignment is already up due Wed. 2am (Tues late nite):
ungraded practice how to enter answers into webassign.
Decimal places: if correct answer is 10.1 cm, will 10 cm
work? 2% tolerance
Assignment #2 will count towards grade!
Have 1 full week to make sure you have no problem with
webassign.
Webassign will list problems we chose from back of chapter
But everybody gets a different set of numbers
e.g. your HW problem might involve dropping an object
from 1 meter
your friends problem might be 2 meters
your friend will not get the correct answer if he/she copies
from you.
5 attempts: after you submit each answer, you can find out if
you are correct.
Due 2am Wednesday
You are encouraged to finish the assignment early,
Can get help from office hours, discussion
sections
Tuesday night is your last chance of completing the
assignment.
Will not be able to get help if you have problem.

Discussion section
Click on discussion sections: not yet populated
In addition to the two large lectures, there are also two discussion
sections per week
TA will answer questions
Do the reading and have questions, they will help you.
If no questions, they will do examples that help HW
Classes are much smaller, easier for you to ask questions.
Please make use of this help
TA’s will enter their office hours
Office hours: Can go to any one, does not need to go to your
own
Actual class of discussion: need to go to your own.
Because of quiz grade
Quiz
Instructor will explain
20% of total grade
14 weeks of class, but only 10 quizzes
not on week of exam, not this first week
have 15 minutes to solve problems
maybe at the beginning, end or middle of a class, no notes
only part of the course that will be curved: 15/20 mean
if not 15, will adjust
need 85% to get A
clickers (lecture)
will ask questions during lecture and you need to submit an
answer through remote
5% of grade.
Ask John…………..
scheme: 2 points if correct
1 point if incorrect
0 point if no answer
Incentive to come,
Even if you enter the wrong answer for all questions,
Your score will be much higher than somebody
who does not come to class
For us to know how well we get across, immediate feedback
May choose to repeat a topic if 90% of the class get it
wrong
There are no set number of clicker questions per day.
Sometimes only 1 or 2, sometimes more, only one
graded (announced)
Bring calculators
15 % drop on clickers
if at the end of the course, you have 85% of clicker questions
correct you will get a full score of 5/5
you do not have to answer all questions correctly to get a
perfect score
maybe you are sick and cannot come to class,
OK because of the 15% rule: you can still get a perfect score.
If you are missing a few weeks of class, you need to talk to
me.
15% also applies to webassign
will start clickers on Thursday: get one!
Will not count clicker response in the first 3 weeks.
Will follow all procedures,
I will ask clicker questions
Your scores will be emailed to you
If your clicker is not working properly, you will
notice and find a remedy.
You have 2 weeks. (start grading 3rd week)
You should be very familiar with clickers when we start
counting the scores.
Cell phones off
Midterm exams in evenings (2)
dates are posted in the calendar
formula sheet: 1 double sided sheet of paper.
Prof. Chan and I do not pick the exam dates. As far as we know,
both dates are not religious holidays.
If you cannot make the exam, you need to talk to me or Dr. Chan.
If you can convince us that your reason is legitimate, we will
accommodate in two ways:
(1)
take the exam a little earlier (1/2 hour to 1 hour)
(2)
universal makeup at the end of semester. Student A
might miss exam 1 with a legitimate reason. Student B might
miss exam 2. Both will take the same universal makeup in
addition to the final. The universal makeup will cover all
material in the course, just like the final.
Emails: we will respond to email
Only from UF gatorlink accounts send to
ilovephysics@phys.ufl.edu
Calendar:
Who is lecturing, date of exam, final
Reading
Lecture notes:
Some ppt, some board
Try to post Ppt posted the night before. Encouraged to print out.
We also write on board. The important parts will also be posted,
after the lecture.
Clicker questions will be posted afterwards.
