Welcome to
Physics 105, a continuation of 100. The course will be run in a similar way to
100, with a few changes that I’ll explain on the first day of classes. We will
cover most of the rest of your intro text, *College
Physics* by Hugh Young etc. 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 soon agree) very 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.

The class meets MWF at 9am, and class attendance is important/essential to your success. I expect that we will all be here for every class meeting. If you have to miss a lecture due to illness or a personal emergency, please get the notes from a classmate. I do not take attendance but I do notice when students are routinely absent.

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) |

Quizzes | 2 Quizzes =5% |

Lab | 20% |

Homework | (18-2) HW’s = 15% |

**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 2/18/16 and the
second on 4/7/16. The final exam will be cumulative and is scheduled for Saturday
5/14/16 9am-noon.

**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. A third quiz is scheduled near the end of the semester and is optional. If you have to miss Q1 or Q2 you should definitely take Q3. If you take all 3 quizzes, only the top two will count toward your grade.

**LAB:**

Lab starts next week and meets from 1-4 Tues/Wed/Thurs. There are 11 labs; we have two extra weeks and will not have lab during weeks when midterm exams are scheduled.

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

**HOMEWORK:**

Homework
is an important part of your work in this course because the best way to learn
the physics is by practicing. Problem sets will normally be due every other
class period at 9am. So, Friday of the first week, Wednesday of the second
week, Monday and Friday of the third week …... Your questions and problems will be graded
and solutions will be posted on Blackboard. Please make your HW solutions neat
and easy to read. __Show your work__! We cannot give you any credit for
correct answers if you give no justification. __Underline__ or **highlight** your final answer so the
grader can find it.

For
the sake of the graders (and for fairness) late HW is not accepted. I will drop
your lowest 2 HW scores when compiling final grades, so if you have a
particularly busy week with other classes, or if you are sick one week, you should
take a pass and skip the 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 from me with homework problems when
you are stuck. But please realize that the word homework contains the word
“home” for a reason. Figuring out how to apply the laws of physics to assigned problems *by yourself* is the way to learn this material. Watching someone else work out a solution is
no substitute.

You may also use the Q-lit center as a resource, and you may discuss the homework problems in general terms with other members of this class. Please indicate on your problem sets when you have done either of these. PLEASE ONLY HAND IN WORK THAT REFLECTS YOUR OWN UNDERSTANDING.
