You have 2 options:
(1) Buy the package in the CSU bookstore: (printed version
of text plus access code]
(2) Buy access code online to http://edugen.wiley.com/edugen/class/cls230592 which gives you the online access and buy a used version
of 6^{th} or 7^{th} ed of text [or print out from Wiley –
but not in Physics Dept!]
Course Material: Physical principles are the foundations
of all natural science. The
fundamental laws of physics are explained and are illustrated using examples
(mostly) from biology and medicine.
Supplemental Instruction (SI): This course offers Supplemental
Instruction for students who wish to participate. An SI Leader (a fellow CSU student) has been assigned to
this course and will hold regular sessions outside of class time to allow
students to review material discussed in class, discuss and add to lecture
notes, apply reading comprehension strategies, get help with assignments,
prepare for the tests, etc. Research suggests that students who attend
early and often can score up to one letter grade higher than if they did not
attend an SI session.
Students who cannot make these times but wish to make use of
Supplemental Instruction should contact the SI Leader or the Tutoring &
Academic Success Center (2166872012, tutoring@csuohio.edu). Times will be
announced in the first week of class.

Review

Examinations: 3 midterm exams
and one final exam. The
final exam is comprehensive and covers problems from all Òunits.Ó If the score of a midterm exam is lower
than the score of the final exam, the midterm exam score is replaced by the
corresponding score of the final exam.
That is, you get a second chance for all midterm exams! No makeup exams for the midterm exams
will be offered.
The midterm exams are one hour each. Practice exams will be posted on the
website. The exams are closed
books and notes, however a Òcheat sheetÓ will be provided.
Calculators are allowed for all exams.
Exam
1: Tues 9/20; Exam 2: Tues 10/18; Exam 3: Tues 11/15
Homework: Homework is assigned each
week. We use the Internetbased WileyPlus
system
from Wiley. Detailed solutions of the homework will be posted on the WileyPlus
course website.
WileyPlus is setup such that each student has
his/her individual numbers. Each
time you log on, the system ÒremembersÓ you and returns the same set of
numbers. You have three trials.
Quizzes: There are two quizzes for each lecture period. One quiz before the lecture that and
one quiz at the end of the lecture.
All quizzes are multiple choice questions with [mostly] qualitative
questions. The quiz prior to the
lecture is done via WileyPlus. A
correct answer earns 2 points, a wrong answer 1 point.
Laboratory: The laboratory part has
15 labs. A lab report must be
written for each lab.
Grades: The grade for PHY 231 will be based on a
maximum of 1000 points according to the following scheme:
Midterm
Exams 
300
points (100 points each) 
Final
Exam 
300
points 
Homework 
200

4055; F: < 40]
Additional
Material: Scientific calculator
[with trig functions] such as TI30, or the Scientific Calculator from
CVS. Graphing calculator is not required [or
necessary].
Computer Labs: The computers in the
Physics Department are available if no class is using the lab space. Use CSU Id
to login. Note that you are not allowed to download any software on the
PC. Also, do not print entire
chapters out of Cutnell&Johnson.
MCAT: WileyPlus has additional material for each
chapter as a preparation for the MCAT.
Students taking the MCAT are strongly encouraged to do all the problems.
Lecture notes: Material not covered in Cutnell & Johnson will be posted
on course website.
Partial list of biological and medical
applications:

conservation]
Running and walking [Circular motion]
Swimming [momentum conservation]
Basal metabolic rate [Energy and Work]
Biomechanics of trees and plants [forces and
torques]
Physics of air bubbles [surface tension]
Properties of cells [surface tension]
