Course Description (from the campus bulletin): Physics 3 is the first half of an introductory, calculus-based, physics course for science and mathematics majors, covering the laws and principles of mechanics, thermodynamics, and waves.

Course Objectives: Students will learn the principles and applications of mechanics and fluid dynamics through classroom lectures, problem solving sessions, and laboratory work.  Student knowledge will be evaluated through the use of quizzes and tests. Ultimately, this class should improve your:

Grading Policy: Final grades will basically follow the traditional divisions at 90% (A or A-), 80% (B+, B, B-), 70% (C+, C, C-), and 60% (D), with minimal adjustments at the end of the course based on how the class proceeds.

Labwork 20%
Quizzes 20%
Classroom Work, Participation, and Attendance 10%
Test 1 15%  
Test 2 15%
Final Exam 20%

Extra Credit: There will be no extra credit or extra credit papers, Do the homework, labs, and take the quizzes and tests, and everyone can do well in this class. As the semester progresses, there is less and less to be done to increase your grade.

Class Work & Participation: Everyone starts with 90% participation grade. Subtractions are made for being disruptive (excessive talking, ringing phones, being late, etc) as well as excessive absences. Additions are made for contributing (questions or answers) to class discussions. Problems will also be given to be done in class. These problems can be done in groups (up to 3 people). The intent of these is to have you benefit both from working in groups and have my (limited) assistance at making it past the stumbling blocks of problem solving.

Homework: Homework assignments will be presented in class and will generally consist of problems from the required text. The homeworks will not be graded. Instead, quizzes will cover the material and problem solving skills. Even though the homework will not be graded, the homework problems must be done in order to gain mastery of the material and skills necessary for both the quizzes and tests.

Quizzes: Quizzes will be 20 minutes long given in class usually every week in which we don't have a test. The intent of the quizzes is to insure: (1) that you have read the chapter to be covered that day and (2) that you can solve problems from the previous material. Hence, questions on the new material that you are to have read will be very straightforward covering, for example, new vocabulary. Questions on the older material will be more along the lines of the easier homework problems. I will drop your lowest quiz grade. In many cases, missed quizzes can be made-up if taken before the subsequent clas s (either section), generally at 9am by stopping in my office. Only with good an d verifiable excuses can quizzes be made up after the subsequent class.

Tests: The class will have two tests as scheduled on the syllabus. Each test will cover the material presented since the previous test (to be precise, much of what we will learn applies throughout all the chapters, however, the questions will be geared towards specifically covering material presented between the tests). The tests will be given during classtime.

Final: The final will be held during the time dictated by the Registrar during Exam Week and will be similar in style to the two tests.

Lab: The lab is integral with the lecture. You receive a single grade for the class which represents the work you do in lecture and lab. I will drop your lowest lab grade. As part of your lab work will be a lab final covering both the content of the labs and good lab practice in general.

Cheating: You are encouraged to work on homework problems with others. However, you must work alone on quizzes and tests. On quizzes and exams you may use only a calculator (not a cell phone's calculator) and writing utensils; The class therefore requires a scientific calculator, separate from any mobile, internet-connected device. I will give you an equation sheet for each test.

Misc: If you are not physically present for a lab (even if a group lab writeup), then one can't receive credit for it and it's cheating to add your name to any writeup. No sharing of calculators until the owner of the calculator finishes the quiz or test and shows the instructor that the calculator has been adequately cleared.

Other Resources: Department-provided tutors, library books, office hours, and supplemental texts provide additional assistance.
