PHYS 101 - Principles of Physics

Instructor: George Barrick

Fall Semester 2012




I’ll be teaching two sections of Physics during Fall Semester 2012. To determine whether you are in fact enrolled in one of George Barrick’s sections of this course, compare the course information in your schedule to see whether your section number of PHYS 101 has either of the call numbers (10848) or (10849). Section (10848) meets at 09:10 MWF in PE MCC. Section (10849) meets at 13:50 MWF in TNSC 014.

The text for Principles of Physics (PHYS 101) is the seventh edition of College Physics by Wilson/Buffa/Lou (ISBN 97803-2160183-4). It’s available from the Walsh Bookstore (for $230.80 new/$173.10 used). Most students of this course will need to register separately for one of the laboratory sections. The text for the lab. is available only from Walsh bookstore ($30.40 new/$22.80 used). Another good source for the textbook (but not the lab. book) is Barnes & Noble. When using e-commerce sites, you’ll need to wait a couple days for shipping. Keep in mind that Walsh Bookstore will buy back relatively undamaged books in December at approximately 15% of the original retail price (though not e-books), and so it’s not a bad idea to keep your books in good condition.


A scientific calculator is recommended for the course. The recommended calculators are the TI-30XA, TI-34 II, TI-36X, TI-83 Plus, TI-84 Plus, TI-89, and TI-89 Titanium. These vary in price from $13.98 up to $171.98. The recommended calculators may be used on tests and on the Final Examination. Calculators, cell phones, PDA’s or laptop computers that might either store text notes or host wireless network links may not be used during quizzes or tests.


The software package Mathematica is a common (and useful) piece of software for students in academic settings. Some students prefer Matlab for extended computations. A software suite that is similar in concept to Matlab is GNU Octave. The important difference is that GNU Octave is free. None of these are required for PHYS 101 since most calculations in this course are easily performed on a hand-held calculator. Students will need to use either Ms. Wordpad or Ms. Office Word with the Equation Editor 3.0 in order to type up homework submissions that include some mathematical formulas.


One component of the grade in the class is quiz scores. Quizzes will take place frequently as part of the class period. It’s a good idea to keep up on the class schedule and class assignments, so as to be prepared whenever quizzes occur. Something on the order of 12 quizzes at 10 points each will be recorded during the course of the semester, though only the highest 10 of these grades will be used for each student’s quiz score. When you are absent from class, you’ll need to notify the instructor on the day of the quiz in order to make up quizzes that you miss. All students must make up missed quizzes within two weeks of the day the quiz was presented.


Daily homework from the assignment sheet will not be turned in for class credit, though it is these examples that will be covered every day in class. Five short homework assignments that require more careful write-ups will be turned in for 20 points each. These assignments may involve some graphing and numerical computations, and students are required to submit these in a timely fashion in the form of typed hardcopy. Homework that is turned in late will be subject to penalties. Homework turned in more than four weeks after the due date will receive no credit.

Final Examination

The final examination meets on the same day for the two sections of this class. The morning class (10848) takes its examination on Monday December 3 at 8:00 a.m. in PE MCC. The afternoon class (10849) writes the examination at 3:00 p.m. on Monday December 3 in TNSC 014. All of the information presented here, as well as more detailed things regarding grading policies etc. can be found in the class syllabus, the class schedule and class assignments.

All of the quizzes will be posted here within a few days after they’ve occurred in class. All students are encouraged to look through these old quizzes as a study guide.
