Thrust
What is Thrust?
Measure of how much the engine provides propulsion.
What is Drag?

What is Viscosity?
A measure of a fluid’s resistance to flow
What is the difference between a control surface and a stationary part?
Control surfaces can be moved
List three Stationary parts.

What is Induced Power?
How much thrust your aircraft is capable of producing from one or more engines
What is Parasitic Power?
How much drag your aircraft has while in motion
What is the Coanda Effect?
The tendency of a fluid jet (like air or water) to adhere to a nearby surface, even when the surface curves away
List four Control Surfaces?
Slats, Ailerons, Flaps, Elevators, Rudder, and Trim Tabs
