Welcome to Physics 205, a
continuation of 200. This class meets MWF at 11 am, and class attendance is
important/essential to your success. I expect that we will all be here for
every class meeting. We will cover most of the rest of Giancoli. We do almost a
chapter a week; it is a fast pace and requires consistent hard work on your
part. The subject material is challenging
and (I hope you’ll agree) interesting. We spend a fair bit of time of electricity and magnetism, then move on
to optics and finally, during the last month, we study the amazing physics of
the 20^{th} century – Special Relativity and Quantum
Mechanics. That’s the best part.

Your grade in this class will be
calculated using the following weighting:

Exams 60% weighted as
follows: 1^{st} exam @ 10-20% 2nd 15-20% and final exam @ 20-30% (%’s
chosen to optimize grade).

Homework (18-2)
HW’s = 15%

Quizzes 2
Quizzes =5%

Lab 20%

**LAB:
**

Lab meets from 1-4 Monday-Thursday
(starting this week). There are 12
labs, so we have two extra weeks. We will not have lab during weeks when
midterms exams are scheduled.

Grades for individual labs will
depend on your participation during lab period and on your written work.
Detailed information about how your lab work is assessed and graded will be
explained this week in lab – and is similar to the system you are
familiar with from last semester. If you have to miss a lab because of illness
or a scheduled college activity, please let your lab instructor know ahead of
time so we can reschedule.

**HOMEWORK:
**

Homework is an important
part of the course because the only way to really learn the physics is by
practice. Problem sets will normally be due every other class period at 11am.
So, Wednesday of the first week, Monday of the second week, Fri of the second
week …... Make your HW
neat and easy to read. __Show your work__!

We can’t give you any credit for
correct answers if you give no justification. __Underline__ or **highlight** your final answer so
the grader can find it.

Your questions and problems will be collected and solutions will be posted on Blackboard. Your work will be graded and returned. For the sake of the graders (and for fairness) late HW is strongly discouraged and must be penalized: -20%/day starting the first day. I will drop your lowest 2 HW scores when compiling final grades, so if you have a particularly busy week with other classes, you may take a “pass” and skip that problem set. Of course, you are still responsible for the material, and can use the solution set as a study aid. Office hours are scheduled so that you can come and get help with problems:

**OFFICE HOURS**

MONDAY 4-5pm

TUESDAY 3-4pm

WEDNESDAY 3-4pm

FRIDAY 3-4pm

TUESDAY and THURSDAY mornings by appointment

You may also use the Q-lit center as a resource; please indicate on your problem sets when you have done so. You are also encouraged to discuss the homework problems in general terms with other members of this class, BUT PLEASE HAND IN WORK THAT REFLECTS YOUR OWN UNDERSTANDING.

**QUIZZES**

We will have two quizzes this semester on Fridays of weeks 2 and 8 that count for a small portion of your grade. They will take 10min of class time and will be based on homework problems and class notes.

**EXAMS**

Two midterm exams are scheduled for
the 5^{th} and 10^{th} weeks of the semesters on Thursday
evenings. The first midterm is on 2/16/12 and the second on 4/5/12. The final
exam will be cumulative and is scheduled for Tuesday 5/8/12 7-10pm.
