Physics 142 -- Dr. Turcan

Spring 2007

______________________________________________________

SYLLABUS:
Principles of Physics II
The second of a two-semester series in general physics. This survey course will use algebra, trigonometry, and calculus and is recommended for chemistry and zoology majors. It also satisfies the requirements of medical and dental schools. The course is a continuation of PHYS 141, and covers waves, electricity and magnetism, optics and modern physics.

*Text
* Topics
We will follow the text book as closely as possible.  We will not be able to cover absolutely everything, but most of it.  I will let you know what chapters to read, as we go along.  Topics I expect to cover this semester:
  • Electricity and Magnetism:  electric fields, electric potential, capacitance and dielectrics, current and resistance, circuits, magnetic fields, inductance
  • Light and Optics:  nature of light, image formation, interference, difraction
  • Modern Physics:  relativity, quantum physics (introduction), particle physics

* Lecture and Lab Schedule
This is the default schedule, and may be adjust it as the semester progresses.
Homework will always be due Wednesday of each week, unless otherwise stated.
Quizzes will be each Friday, at the end of class.

  FINAL EXAM 5/15

* Grading
You will be required to demonstrate your abilities both to do traditional problem solving and also to answer “conceptual” problems that require little or no calculation.

EXAMS:
There will be three 50-minute exams and one final exam.  You may bring one 4x6 index card, with whatever you want written on it, to the first exam.  You may bring the cards from the previous exams plus one additional card to each subsequent exam.   The exam will include problems and conceptual questions.  You are responsible for showing up on time with a working calculator.  The exam sheets will contain any numerical constants you will need.  Make up exams will be given only under extraordinary circumstances, and if arrangements are made with me ahead of time.

HOMEWORK:
Homework assignments will be given in class, and will have to be done in writing and turned in at class time, usually each Wednesday.  I believe that the best way to learn physics is to sit down and work out problems on a piece of paper.  The grading of the homework assignments will be done by your TA.  The TA will score all problems with a 1 or 0, depending on whether the right final answer was obtained and work was shown (worth 10 points).  One problem (worth 5 points) and one "mini-essay" question (worth 5 points) will also be randomly chosen to be graded in detail.  The total homework score will then be calculated out of these threee parts (maximum 20 points).

QUIZZES:
There will be a 10 minute quiz every week at the end of class Friday on the material covered in the HW you turned in that Wednesday.  The quizzes will start at 11:40, and be collected promptly at 11:50 AM.   Sometimes the quiz will be a traditional problem, sometimes a conceptual one.  I will drop your two lowest quiz grades.  Makeup quizzes are not allowed.  If you miss a quiz due to illness, that will be one of the quizzes that is dropped.  There will be no quizzes during exam weeks.

LABS:
You will do a total of 11 laboratory assignments.  For each lab, you must give your TA a completed “check sheet” and written answers to the questions at the end of the laboratory write-up.  Your lab grade will be based on these questions (maximum 20 points, equally divided into the number of questions).  The TA will deduct points if your handwriting is illegible, or if your answer is hard to understand because of poor grammar.  Each lab must be turned in before the end of the laboratory period.  You will do all your work in class.

FINAL GRADE:
The final grade will be calculated as follows:
  • Homework:  20%
  • Lab reports:  20%
  • Quizzes:   10%
  • Exam I:  10%
  • Exam II:  10%
  • Exam III:  10%
  • Final exam:  20%
