http://moutouxphysics.weebly.com/ Summer Assignment: My desire is to dive into the meat of physics as quickly as possible. After all, it has been often noted that “Physics is Phun!” Therefore, this assignment is intended to review and/or learn a few of the tools we’ll be using in class. We’ll, of course, go over the new tools the first week of class. Then, let the “phun” begin! 1) Acquire the text: Physics, 4th edition, 2009 James S. Walker ISBN-13: 978-0-321-61111-6 ISBN-10: 0-321-61111-X This is the same text that has been used for several years so you may be able to obtain a copy from an older friend. If not, many used copies are available online. 2) Read Chapter 1, pages 1-10. 3) Practice significant figures at http://www.physicslessons.com/exp43b.htm until you feel confident in your ability to identify the number of significant figures in a number. We’ll quickly go over significant figures in calculations the first week of class. 4) Review scientific notation at https://janus.astro.umd.edu/cgi-bin/astro/scinote.pl until you feel sufficiently refreshed. 5) Attempt problems 5, 8, 9 & 10 on p15 to practice dimensional analysis. In order to do these problems you will need to use Table 1-5 and know that x = distance, v = velocity, a = acceleration, and t = time. Dimensional analysis is a great review of basic algebraic equation manipulation. 6) Review the metric system by completing the assignment “Operation Time Out”. The metric system, at this stage of your education, can be notoriously tedious to review. Yet, it is essential for physics as nearly every calculation and measurement this year will require the use of the metric system. This assignment is intended to provide a fun challenge to review the structure of the metric system (base unit + prefixes) and get you to think outside of the box. For this reason students can sometimes become frustrated. Don’t. It’s not worth it. Instead read the instructions and the grading rubric very carefully. There are many embedded hints on how to proceed. Also, please feel free to discuss with parents, siblings, friends, and generally anyone not deemed a spy. |
