Flight, Motion, and the Design Process

“Describe how Newton's Third Law of Motion applies to the generation of lift by an airplane wing. Explain how the four forces of flight (lift, weight, thrust, and drag) interact when an airplane is accelerating during takeoff. Imagine you are using the design process to improve the fuel efficiency of a model airplane. Describe how you would "build and test" your solution, and what you would look for during testing to determine if your design is successful.”
