You need to have the following skills - pace yourself to complete these reviews before August 26th:

Conversions
Take a look at this chart. You should have memorized the prefixes from 10^-12 to 10^12. That means pico, nano, micro, milli, centi, deci, (deka and hecto), kilo, mega, giga, and tera. Deka and hecto are rarely used. For now, ignore the bottom part of the chart.

Here is a good on-line metric prefix quiz site where you can test to see if you have the common prefixes under control. (Scroll down to "PRACTICE")

Addition and Subtraction of Fractions and Scientific Notations
When you go to this website scroll down to SUBMIT and the screen will generate a fraction worksheet for you to work WITHOUT A CALCULATOR. Work the first 5 problems and then hit answer key. If you can do them correctly without a calculator you are ready to move on. If you are stuck, email me or ask mom and dad for help.

Scientific Notation
Historically, students taking physics come in with a strong understanding of scientific notation. GO HERE and click on GO to test yourself. Run as much as you need to review and confirm skill level.

Multiplication Table
About 60% of students underperform in simple arithmetic, preferring to rely on the calculator. This make life miserable because the basic problem solving skills required for math carry over to techniques required for solving physics problems. In short, can you tell me what 9 X 7 = without a calculator? If not, try this website. Make a blank copy on graph paper and work on filling it in WITHOUT A CALCULATOR. Soon, you will notice a pattern that makes the arithmetic easy.

Significant Figures
Do you remember the rules for sig figs? You can review them HERE, and they have practice problems with answers.

Only For The Most Awesome Students:
Introductory lecture 1; order of magnitude and error analysis: CLICK HERE for an excellent M.I.T. lecture that will really jump-start you for the first day of school (38 minutes). NOTE: The video "Powers of Ten" by Charles and Ray and Eames has been removed from this lecture, but can be seen HERE. Please watch it!

Our textbook:

Very useful... Here is a link to the publishers website CLICK . Bookmark this page! As you can see it has core concepts, practice problems, and (limited) solutions to homework problems. This link will also appear at the top of this page and this web page will back-fill from the bottom up as I add postings. You can wait until the book store opens at GBN or try to get it from amazon.com for less.
