1. Find and record a definition of Bernoulli's principle as it is applied to flight. Be sure to note the source of the definition.









2. Make a sketch, on a separate sheet of paper, of the four forces that act on an aircraft in flight. Circle the forces which are desirable in order to achieve flight. Box the forces which are not desirable.




3. Explain in your own words how lift is created by the use of the shape of an airfoil.













4. Define the following terms:

thrust



lift



weight



drag



airfoil



air pressure



angle of incidence



stall angle



yaw



roll
