7. 2-4 sentence summary (or abstract) of the source an interactive website set to give a deep fundamental idea of jets and there parts and there functions. organized approach describing how it works and basic math behind why it works. Nasa based online textbook ."The creation of the BGA is a research project to explore the use of the personal computer and the Internet to present educational materials to students, teachers, and lifelong learners in a more interactive way than a printed, bound textbook." siad by the website itself. 8.

non. a pure learning tool design to help organize and collect data on the helpfulness and viability of online interactive textbooks.

9. Please explain: to what extent are you persuaded by the author's treatment of the topic i am heavily persuaded due to the fact that this is a NASA site aimed to inform the general mass the basics of aviation for the leading goverment agency in aeronautics and aviation. 10. Key sentences or passages- Transcribe, word-for-word, a total of 4-6 sentences from this source that will likely be worth citing from when you get down to sharing your research findings.

Drag is a **mechanical force **. It is generated by the interaction and contact of a solid body with a **fluid ** (liquid or gas). It is not generated by a force field, in the sense of a [|gravitational field]  or an **electromagnetic field **, where one object can affect another object without being in physical contact. For drag to be generated, the solid body must be in contact with the fluid. If there is no fluid, there is no drag. Drag is generated by the [|difference in velocity]  between the solid object and the fluid. There must be motion between the object and the fluid. If there is no motion, there is no drag. It makes no difference whether the object moves through a static fluid or whether the fluid moves past a static solid object.
