Text:  Douglas Giancoli, "The Ideas of Physics", 3rd edition, published by Brooks/Cole
The textbook is required. This text has been unchanged for several years (but can be found with a variety of different formats, my copy says copyright 2001).
There are many copies available second hand in auction sites and online booksellers.  The book should not cost you a lot of money - $20 should buy a decent copy. Note that the material that will be covered in the tests is that covered in class. Although the order of the book is followed, some subjects may be expanded upon, and some may be shortened.
Grading policy. Maximum total possible 100 points.
  • a) Tests There are 2 in-class tests during the semester, each of which are 30 points. There is a 3rd exam (the 'freebie') given in class the last day of class, Wednesday April 24.  This 'last chance' exam is like a practice final, and is used as a makeup for students who missed a test or for students who want to try to improve one of their test scores.  There is a two hour final exam, worth 30 points, given Thursday, 10:00 am - 12:00 pm, May 2 (final test time assigned by the registrar). That gives 90 points from tests, that is 90% of the grade is in tests. The 2 during-the-semester tests will be in a "short-answer" format - not multiple choice. Both the 'freebie' and the final will be multiple choice using bubble sheets.  Essential formulae will be supplied for the tests. In addition, you may have one (1) crib-sheet for each of the 2 in-semester tests.  Save your crib sheets, you may have three (3) crib sheets for the 'freebie' and for the final.  All tests are closed book.
  • b) In-class Quizzes Use of the H-ITT clickers is worth 10% of the grade. Each question is worth 2 points for a correct answer and 1 point for a wrong answer. One quarter of the questions are dropped.  This generous drop policy is meant to cover all excused absences (religious holidays that are not U of F holidays but which you observe, illness, sponsored U of F activity where you have to be away like a team sport, interviews, weddings, ...  If after these absences you have any drops left, then low scores on quizzes you took will be dropped.) Giving your H-ITT clicker to someone else is considered cheating! 

  • The following is the guaranteed grading scale - 80% for an "A", 75% for an "A-", 70% "B+", 65% for a "B", 60% for a "B-" 55% for a "C+" 50% for a "C", 45% for a "C-", 40% for a "D+", 35% for a "D", 30% for a "D-".  Below 30% is an "E".

  • Philosophy of the course This course is designed for people who do not necessarily have a background in physics. We accent the physics of everyday life. Hopefully this can serve as a foundation that will help if you are going to take, for instance, PHY2053 or PHY2048, as well as being a good survey of the basics of physics that will stay for you for the rest of your lives. There is no obligatory homework (but there is recommended homework). Students who have a good background can do well in this course putting in relatively few hours of work. However, if you do not attend class, you will not only miss the opportunity of getting 10% of the grade, you will also miss the explanations and examples that it will be necessary to understand for the tests. The course moves FAST - often one subject (1/2 of a chapter) per class period. If you miss class, you will miss an entire subject - be warned.
  • Calender of Events You may print this out, but be aware it can change as the semester progresses, depending on how long we take on each subject, how well people do in tests, etc. The test dates are also preliminary.

  • Hints on how to do well:
  • Attend Class Remember, the syllabus is defined by what is covered in lectures. You will not be tested on material not covered in class. The book covers lots of material, not all of which you are expected to know. If you miss class, my advice is to ask a class-mate for notes. I am happy to explain things in office hours which you did not understand. 
  • Be on time for class. Announcements are generally made at the beginning of each lecture, and you are responsible for learning of these whether you attend class or not.
  • If you are struggling, ask for help. The best way to get hold of me is after class, in our assigned office hours, or by e-mail. It is tough to discuss physics by e-mail, so it is better to ask 'how to solve this problem' in office hours so I can understand what you're missing.  If you want to discuss physics and cannot make time during my office hours, I can be flexible, but check with me first.
    Take Notes Something that is obvious at the time is quickly forgotten. When it comes to the night before a test, you will appreciate a good set of lecture notes.
  • Do some problems Here are are a sample of physics problems, and their solutions, taken from the textbook. Really try to work some of these problems without looking at the solutions after a short time - otherwise the exam problems will seem challenging. Note that they are just samples for extra practice, although I promise that doing some of them will improve the score of everyone who is not a born 'A' student in physics. Another great way to be ready for the tests is knowing notes taken in class inside and out.
