Here is a site that I think that you will all like which contains basic physics that will help you depending on your situation. Visit the site on my signature or type in www.apmastersite.us.tc [4] Then click on science links and there should be two physics sites. One main site and a continuation to the main site below it since we could not fit all the info. If you have any more questions please IM at Apfaq or e-mail me through one of the links on my signature (preferably hotmail)
