Meeting Schedule: TR 12:15 - 1:05 p.m. & W 8:00 - 8:50 a.m., LEV 309
Course Description: Kinematics of particles, systems of particles, kinematics of rigid bodies,
Text: Vector Mechanics for Engineers: Statics and Dynamics, 8th Edition, 2006, by F. Beer, et al.
Study, with a problem-solving emphasis, the physics and engineering aspects of: Kinematics of particles, systems of particles, kinematics of rigid bodies, plane motion of rigid bodies, and mechanical vibrations. For example: why a cat is able to land feet downward, regardless of how it is dropped, and what musical notes should be produced by some vibrating objects.
Please read each text topic BEFORE the class it is scheduled for; then in class, ask appropriate questions.
Goals for student learning:
Ability to solve problems involving all topics listed below.
o Kinematics of particles (rectilinear and curvilinear motion of particles)
o Kinematics of particles (Newton's second law and its applications)
o Kinematics of particles (energy and momentum)
o Systems of particles (motion of center of mass, angular momentum, kinetic energy of a system of particles)
o Kinematics of rigid bodies (translational and rotational motion, absolute and relative motion)
o Plane motion of rigid bodies (forces and accelerations)
o Plane motion of rigid bodies (energy and momentum)
o Kinetics of rigid bodies in three dimensions
o Mechanical vibrations (vibrations without damping and damped vibrations)
To develop an intuitive understanding of particle motion.
Appreciation of a practical use of each topic in addition to a conceptual understanding of it.
Suggested Learning Behaviors:
Be an active class participant: Read the material in the text before we talk about it in class so that you are aware of any challenging areas. Ask an appropriate probing question as a difficult subject is covered. In this way you will focus the lecture time where it will help you the most.
Be an active practitioner: Do a representative sampling of problems - it's simple - the more you do, the more you will learn and the better you will do in this class. If your answer does not agree with the answer in textbook, arrive at class a few minutes early. Put the problem up on the board, as far as you can go (i.e., list what is given, what is requested, do as much as you can, sketch roughly, if appropriate, etc. At the start of the class we will talk about how to take the next step and your efforts will insure that we will be talking directly to your concerns instead of rehashing the stuff you already know). Of course, if you prefer, get help with that problem somehow: Learning Center, friend, or develop your "stick-to-it-iveness" and solve it by trial and error yourself.
Don't make the same mistake twice: If you do not get an exam problem correct, find out how to do it in case that type of problem shows up again later in the semester. (Hint: It probably will!) Everything in this course is cumulative and each concept and procedure builds on earlier work.
Work alone, then share your solutions with a classmate. You will find you will solidify and clarify your own understanding of the concepts when you explain them to someone else. If you form a learning/study team with a classmate, you will benefit not only from the teaching experience but also
PHY231 - SYLLABUS - Spring 2009 - Page 2 of 4
from your colleague's efforts and explanations on problems you did not tackle. Agree to a joint study plan, divide up the problems between you, and arrange a regular time to pool your solo efforts. Working both separately and together is usually a more efficient use of your study time than the same amount of time always working alone or always working together.
Expect "surprise" quizzes.

Your grade will be determined from the weighted-average of all your quizzes (some quizzes will be scheduled as surprise quizzes; don't be late to class); (weightings of individual exams to be announced, some quizzes will count more than others). However, students who do not score as well as they wished may study the topic and take a retest (see 5/13 & 5/19 above). The better grade will be retained as the grade for that material. There is no "Curve." Letter grades will be associated with weighted-averages as follows:
A+=96 or higher; A=92-95; A-= 90-91
B+=88-89; B=82-87; B-=80-81
C+=78-79; C=72-77; C-=70-71
D+=68-69; D=62-67; D-=60-61
F = 59 and lower
Homework will be counted, if it would "throw you over the border" between grades in a favorable direction.
"CHEAT-SHEET" - During a quiz or exam, each student may use their own personal single sheet of notes (maximum size = 8-1/2" x 11") - revise and update your sheet regularly.
PLEASE CONSIDER IT A STANDING HOMEWORK ASSIGNMENT TO MAKE YOUR OWN OUTLINE NOTES, AS YOU READ THE TEXT, BEFORE CLASS - This should be the basis for your "Cheat-Sheet."
HOMEWORK: Due at the start of the next class after it was assigned.

SUGGESTED SYSTEMATIC PROBLEM SOLVING APPROACH:
Read the problem twice (the first time to get the general nature and the second time to pick it apart).
Translate and write down the given information into variable statements (i.e., v(0)=5m/s).
List requested quantities as variable statements (i.e., x=?).
Convert all units into a single system (if necessary).
Draw a labeled sketch.
Choose a method (i.e., Newton's 2nd law, or Energy Conservation or ).
Select equations; check off knowns (do you have enough info to solve or do you need to find some more?).
Solve algebraically and substitute numbers only at the end.
Box your answer(s).
Now try to check and see if your result makes approximate sense. - If it doesn't pass a reality check, go back and rethink your entire approach to this problem.
Out of courtesy to other members of this class, cell phones, calculators, and computers should not be brought to any class or exam. If you must have one in your backpack, don't take it out, and please be sure that all ringers and alarms are turned off.
Plagiarism is a serious offence. Give proper credit. Detected plagiarism will be reported and result in an F in this course.
If you have any category of disability, please contact the staff in the Disability Services office.
