Southern Illinois University Carbondale is committed to providing a safe and healthy environment for study and work. Because some health and safety circumstances are beyond our control, we ask that you become familiar with the SIUC Emergency Response Plan and Building Emergency Response Team (BERT) program. Emergency response information is available on posters in buildings on campus, available on BERT's website at, Department of Safety's website (disaster drop down) and in Emergency Response Guideline pamphlet. Know how to respond to each type of emergency.


TEXTBOOK: Physics for Scientists and Engineers (7th Edition) by Raymond A. Serway and John W. Jewett {Brooks/Cole--Thompson} ISBN: 978-0-495-01312-9  

HOMEWORK: There will be homework assignments given during the semester, aprroximately one assignment per week. Not all homework problems will be graded.   However, you must hand-in all of your homework solutions. The homework assingment and solutions for each homework assignment will be posted on the class web site on the day listed on the web page of this course.

It is your responsibility to check the web site to keep track of the assignments.  In order to do this, you should visit the course site at least once a week, if not more often.

In order to really grasp the concepts, you will need to do the homework assignments yourself and to check your skills by comparing your solutions with the ones posted on the web.

Student Conduct Code


  • Below are the prerequisites for this course: 
    1. You must have completed Math 150 (Calculus I) with a grade of "C" or better.  

    Tentatively the following topics will be covered during the semester: 

    Basics: Units, Conversions, Sig figs, etc. (Chapter 1)
    Motion along a st. line (1-D) (Chapter 2)
    Vectors (Chapter 3)
    Motion in 2D or 3D (Chapter 4)
    Newton's laws of motion (Chapter 5)
    Circular Motion and Applications of Newton's laws (Chapter 6)
    Energy, Work and Energy Transfer (Chapter 7)
    Potential energy and energy conservation (Chapter 8)
    Momentum and Collisions (Chapter 9)
    Rotation of rigid bodies (Chapter 10 and 11)
    Torque and angular momentum (Chapter 12)
    Equilibrium (Chapter 13)
    Fluid Mechanics (Chapter 14)
    Oscillatory Motion (Chapter 15)
    Wave Motion (Chapter 16 and 18)
    Temperature and heat (Chapter 19 and 20)
    Laws of Thermodynamics and Kinetic Theory of Gases as time permits (Chapter 21 and 22)


    Since the main objective of this course is to understand and then successfully apply the fundamental concepts of physics to solving problems, it is important to have good math skills. To do well in the course, you need to have good math skills in algebra, trigonometry, and calculus (both differential and integral calculus). I strongly urge you to freshen up your math skills for this course. Please visit the Math Department's web site (see below) to review the relevant material in trig, algebra, and calculus, in particular review the materials posted for math 107, 108, 109, and 150.

    Please remember, in the end, you will earn your grade by your hard work and your performance.


    CLASS WORK: There will be several Homework assignments during the semester. You will be asked to turn these in for a grade. These grades, along with your class participation, will count as your class work grade which will comprise 8 % of your final grade for the course.  

    EXAMS: There will be THREE exams/tests during the semester. The date of the exam will be announced by being posted on the class web site two or three lectures before the exam.  Therefore, it is important that you check the class web site often (at least once per week). 

    The exams will be closed textbook.  However, a formula sheet listing the equations from the chapters over which the exam is based will be posted on the class web site.  It is your responsibility to download the equations, print them, and bring them with you on the exam and the Final Exam days. You are NOT allowed to consult class notes, books, and programmed solutions on your calculators.

    On the day of the exam (or final exam) you can bring copies of Appendixes A and D, however, this does not imply that you will be allowed to consult the textbook during the exam and Final Exam.

    On the day of the exam, bring your student ID.  It will be checked.

    You may use calculators during the exams or final exam, so bring one of your own.  Any information brought into the exams through programmable calculators constitutes academic dishonesty and will be subjected to judicial proceedings according to university rules (see Rule section).

    The exams will be based on any information discussed in the lectures and/or in the textbook.  Predominant content will be from the lectures (this does not mean the exam questions will be identical to the numerical problems we solved in class).  Consequently, it is important for you to attend lectures. 

    The lowest exam grade will be dropped and replaced by your final exam grade automatically if your final exam grade is higher. This constitutes reasonable accommodation for university sanctioned activities scheduled on days when exams are to be taken. It is very important that you do not skip exams just because you want to do so.  If you miss an exam, it will be counted as your dropped exam. Therefore, it is imperative that you take all the exams because that will provide you flexibility and will help you maintain a good grade.



    The exams collectively count 60 % toward the final grade in the course.


    The final exam counts 32 % toward the final grade in the course. The final exam will be a comprehensive exam.

          Final Exam:

     Date: December 16, 2009 (Wednesday)
     Place: Neckers 440


    In case the fire alarm or the alarm is pulled during the exam or the Final Exam: what we will do

    Since we have six exams during the semester for this course, we are required to cover almost a chapter per week.  Therefore, we can not afford to lose any lecture.

    In case the fire alarm or the alarm is pulled during an exam and since we will have to vacate the lecture hall, the exam in question will not be graded. Instead, a replacement exam will be given on Friday at  8 P.M. The exact date will be posted on the web site.

    In case the fire alarm or the alarm is pulled during the Final Exam, then a replacement final will be administered on the Friday night of the final exam week at a place and time to be listed on the class’ web site.


    The following weighting will be used for exams and final exam in computing the final grade:

    Exams    =     60.0 %
    Class       =      8.0 %
    Final       =    32.0 %
    Total      =     100 %

    KEEPING UP WITH GRADES: Grades have been posted.  You should visit office hours at least once after the first three exams to find out how you are doing in the class.  It is suggested that you do so more often.  It is your responsibility to avoid surprises and know how you are doing at any given time throughout the course.
