Unit #1 Speed and Acceleration List of Activities and Assignments Welcome to Honors Physics. The following is a tentative calendar of assignments, laboratories, and tests. Please realize that there may be some activities added or deleted due to the needs of the class. The homework listed is given with answers and is posted on-line on my website at http://www.chatphys.wordpress.com A grouping of homework assignments will be due approximately once a week. See my website and announcements in class for the exact due dates. Homework will be graded by you according to the following scale. 3 = problem completed on your own, with work and answer completely shown. 2= problem completed with help from the website, with work and answer completely shown 1= incomplete problem or no work shown 0= problem not complete Concept 1- Class Procedures Hand Out Textbooks Holt Physics (1999) Discuss Summer Assignment. See website for actual assignment. (Due middle of second week) Concept 2- Metric System and Significant Figures Example Problem Read p. 12 and p. 17 (Blue boxes) as reviews of topics Read pp. 46-47 Concept 3- Lab: “How Fast are You?” Data Collection Concept 4- Post-Lab “How Fast are You?”.

(a) t1 = 4.69 sec; t2 = 85.3 sec; v= 61 m/s Concept 11- Test Review A handout will be given a week before the test with problems that practice similar skills as on the exam. This is solely for your preparation, it will not be collected or graded. Concept 12- Test The test is drawn from AP Physics B problems and New York Regent Exams. The format will be 20 questions multiple choice and three short answer. Some tests will be taken over two days. Concept 13- Test Corrections You will have an opportunity to “go over” your test and correct it. This is an assignment that is added to the test grade.
