At this Web site you can study aerodynamics at your own pace and to your own level of interest. Some of the topics included are: Newton's basic equations of motion ; the motion of a free falling object, that neglects the effects of aerodynamics; the terminal velocity of a falling object subject to both weight and air resistance ; the three forces (lift, drag, and weight) that act on a glider ; and finally, the four forces that act on a powered airplane. Because aerodynamics involves both the motion of the object and the reaction of the air, there are several pages devoted to basic gas properties and how those properties change through the atmosphere. This site was created at NASA Glenn as part of the Learning Technologies Project (LTP) . It is currently supported by the Aeronautics Research Mission Directorate at NASA HQ through the Educational Programs Office at NASA Glenn.
The full SM-14 formula, which you have just read, is usually for complex, ill-structured problems that require research and study. However, problems come in a variety of complexities. Here is a shortened formula: SM-7 For Intermediate-Type Problems and Decisions
www.phunland.com has been redirected to www.algodoo.com . Algodoo was released in 2009 and replaces Phun. Phun was the open beta testing version of Algodoo and as such Phun is no longer promoted, developed or supported. Algodoo has been much more developed since Phun and now comes in two different version. With more tools to play with, with a better visualization of physical properties, e.g. force vectors and velocities, as well as a versatile plotting system, new GUI and start-up tutorials, and lesson plans for educators. And lasers!!
