WarmUps by chapter:

Homework by chapter:

Class will be a mixture of lecture, group work, discussions, activities and demonstrations, and its success will depend on your participation. Questions are welcome ANY TIME.


I have several goals for this course, some are academic and some are not. The non-academic goals that are very important to me are showing you how much fun physics can be, how relevant it is to everyone’s daily life and that you CAN do it!

There are many skills and ideas that I hope you will have understood and mastered this term. The concepts that you will learn to understand and apply are:

  • electric and magnetic fields and forces, what causes them, where they exist in our universe and how they behave
  • how and why electric circuits work
  • what light is and how it behaves in different situations
  • we will begin exploring some modern physics including relativity, quantum physics, atomic and nuclear physics

Among the skills you will practice and apply are:

  • critical thinking
  • problem solving techniques
  • mathematical skills such as setting up and solving algebraic equations, working with trigonometric functions, finding the correct direction for a vector quantity and determining the correct significant digits and units for a quantity

In lab we will continue to work on developing and applying knowledge of concepts and practice hands-on skills:

  • acquiring reproducible data
  • interpreting them within a theoretical framework
  • understanding the application and limitation of experimental data and theoretical frameworks to the natural world
  • wiring and understanding circuits, exploring charge, lenses, light, and radioactivity
  • analyzing uncertainties and errors on measurements and calculations
  • writing and re-writing a scientific paperusing Excel and Word


Your grades will be made up of many parts such as WarmUps, homework, lab and exams.  You will set the percentages for each, within reason (see grading contract).


WarmUps are to help you start thinking about what we are going to cover in class and to let me know what you understand and what we need to work on. Because they are to help you focus on important or difficult concepts we haven’t yet covered, they will not be graded on whether the answer is correct, but instead on whether you have given a thoughtful and complete response. I will use them to structure what we do in class each day, so they will be due by 10 am on the day we are to cover that material. If you click on the above link, you will find the WarmUps. Copy and paste the WarmUps into an email message and answer after each question, then you can send it to me when you are satisfied, just as you would any email message. If you have questions about how to do this or if something appears to be not working, please let me know immediately.

WarmUps will be graded according to how much thought you put into the question and not on whether it is right or wrong. A wrong (or right!) answer with an exceptional, thoughtful and complete response will earn a 10. A well thought out answer, right or wrong, will earn a 9. An answer with little or no explanation will earn a 6. If a WarmUp is not turned in or is turned in late, it will be counted as a 0.


I believe that understanding physics is nearly impossible without using and applying the concepts, therefore homework will be assigned for every chapter. The above link has the homework assignments for the semester. I encourage talking with others in order to learn and understand the problems, but suggest that when you write up the solutions you do that on your own. If you truly understand it, you should be able to do and explain it in your own words.

If you work consistently and are willing to ask questions, weight homework strongly. I will work with you to arrive at understanding of every question you bring me and will help with any problem. That means that it is possible to get 100% on every homework assignment. However that also means you will have had to try it in advance so that if you have questions, we have time to work on it.

Homework will be graded on a 10 point scale. A 10 will be awarded for completely correct answers, including units, significant digits and direction, if applicable.  I will award partial credit, with the lowest grade being a 4, if the problem was truly attempted.  A 4 means that I acknowledge that you tried, but unfortunately you were on the wrong track. A 0 means that a problem wasn’t attempted, no effort or thought was apparent or an answer was provided with no work being shown.


Your lab grade will be based on a formal laboratory report and its re-write as well as on your understanding of and effort in the individual labs, as determined by the pre-lab, questioning at the end of lab and your lab notebooks. At the end of each lab, the instructor will have a discussion with each group to answer questions and make sure you understood what the lab was about: what was measured, why it was measured, how the results were determined and what they mean. You will be required to buy a lab notebook (a composition book, quadrille ruled) and to keep your lab notes, data and analysis in those notebooks. They will be left in lab and checked by TA’s.  You are welcome to use your notebook from last semester.

Always come to your lab section unless you have previously made arrangements with BOTH lab instructors. EVERY lab must be satisfactorily completed. If you do not pass the lab portion of the class, you do not pass the course.

*(Formal lab report for this experiment due on Monday Feb. 20)

Your lab grade will be based on a formal lab report and its rewrites (50%) and on your understanding and effort in the individual labs, as determined by questioning at the end of lab and your lab notebooks.  At the end of each lab, the instructor will have a discussion with each group to answer questions and make sure you understand what was done: what was measured, why it was measured, and how the results were determined.  You will be required to buy a lab notebook (a composition book, quadrille ruled) and to keep your lab notes, data and analysis in those notebooks.  (You may use your 113/213 lab notebook if there is sufficient room left).  Notebooks will be left in lab and checked by the TA’s.


There will be two exams during the term and a final. All will be closed book, closed notes.  The final exam is comprehensive and will be Monday, Apr. 9 starting at noon.

College Policies:

Non-Discrimination Policy

Hiram College is committed to equality of opportunity and does not discriminate in its educational and admission policies, scholarship and loan programs, and athletic and other school-administered programs on the basis of race, color, national origin, religion, gender, sexual orientation, age, or disability. The College will not tolerate harassment, prejudice, abuse, or discrimination by or of any of its students, faculty, or staff.

Communication with Parents

Hiram College encourages students to speak directly with faculty regarding course content and performance.  Students are also encouraged to speak with their parent(s), particularly if the student remains dependent on parent(s) for financial support.  Faculty may choose to speak with parents, but generally, faculty will require a written FERPA waiver to be signed by the student before speaking with a student’s parent.  FERPA waivers may be found at the Registrar’s Office in Teachout-Price, or online.

Disability Support Services for Students with Special Needs

To arrange for support services, a student must submit appropriate, current, detailed documentation to the Director of Counseling, Health and Disability Services (CHDS) together with the completed online service request form.  After verification and with the student’s consent, the Director of CHDS will notify the student’s faculty of the appropriate accommodation services.  Faculty are not permitted to make accommodations without the authorization of the Director of CHDS.  Hiram College adheres to Section 504 of the Rehabilitation Act to provide requested services for disabled students as specified by the requirements contained in the Americans with Disabilities Act (ADA) policy  guidelines.  The Director CHDS is located in the Julia Church Health Center (330-569-5952) P.O. Box 67, Hiram OH 44234.

Academic Dishonesty

There are many forms of academic dishonesty, including plagiarism, the giving or receiving of help in any form on an examination, the sale or purchase of papers and test materials, the abuse of computer privileges and regulations, the misuse or abuse of online or library resources, and any other action which debases the soundness of the educational process.  Any student who violates the integrity of the academic process will be subject to punishment, including possible dismissal from the College.

Hiram College believes that the development of intellectual honesty is at the heart of a college education. The process of education is severely compromised if we cannot depend on the academic integrity of each member of the community. Moreover, the principles of academic honesty are aligned closely with the principles of good scholarship and research, principles of critical thinking and reasoning, and the standards of professional ethics. Thus, students who fail to practice academic honesty not only risk losing the trust of the academic community, they also fail to develop the most essential skills and abilities that characterize a college graduate.

Faculty members, librarians and staff are expected to report all instances of academic dishonesty to the Associate Dean of the College, who will provide advice on an appropriate action.

Grade Appeals

Academic performance is to be judged solely by individual faculty members.  Grades are not subject to alteration based on the amount of effort exerted by, or past performance of, a student.  Faculty are expected to provide performance criteria (such as attendance policies, deadlines, assignment expectations, etc.) as part of course syllabi or distributed assignments, but assessment of student performance in meeting said criteria is for the individual faculty member to determine.  If a student believes that criteria were ignored, or that work submitted was not included, the student should consult the “Student Academic Responsibilities and Performance” section of the Hiram College Catalog at home.hiram.edu.   Therein is provided the process for grade appeals.  Please note that all grade appeals reside wholly with the professor alone until the official posting of grades by the Registrar.
