Thanks for the help you have shown me so far, it has been very much appreciated. I am preparing for my first Physics I exam and would like your opinion. We are allowed a single 4 x 6 index card to take to class and use on the test. We will also be provided formulas and conversion factor data. If this were your first test, what information would you put on that card? This course is Trig based and I am fairly confident in my ability to use it on the test. There will most likely be questions regarding Order of Magnitude calculations, Conversion of Units, Motion in One Dimension with Constant Acceleration, Vectors and Two-Dimensional Motion, and Projectile Motion. Your recommendations please.
