# Beginner's Guide to Aeronautics Fundamental Terms Answers 1. G This decreases when the spoilers are used. A. Weight 2. F The faster the air is pushed through the jet engine, the more forceful this is. B. Newton's First Law 3. I This, along with weight, acts as resistance to aircraft motion. C. Vortices 4. E If thrust is greater than drag, this law describes the increase in velocity. D. Streamlines 5. B When thrust and drag are in balance, this law explains why the aircraft has a constant velocity. E. Newton's Second Law 6. H Jets produce thrust through the application of this law. F. Thrust 7. A For an aircraft to fly, the lift must be greater than this force. G. Lift 8. D This is described as the flow of air along a smooth path. H. Newton's Third Law 9. C This swirling flow occurs near the wing tips. I. Drag
