- Matter may exist in what three states? - -Solid, liquid, and gas.
- Define kinetic energy? - -Energy of motion.
- Work is the product of what two factors? - -Force and distance moved.
- What are the parts of a lever? - -A rigid bar and a pivot point called the
fulcrum.
- A wheelbarrow is a example of what class of lever? - -A second-class lever.
- Are all three states of matter affected by thermal expansion and if so,
which state is affected most? - -All three states are affected, with gas being
affected the most.
- What is a British Thermal Unit? - -The amount of heat energy required to
change the temp of 1 pound of water 1 degree Fahrenheit.
- Name the three methods of heat transfer? - -Conduction, convection and
radiation.
- What term defines the temperature at which all molecular motion ceases? -
-Absolute zero.
- Can liquids be compressed? - -No, liquids are generally considered
incompressible.
- What are the customary units used to express hydraulic or pneumatic
pressure in the U.S.? - -Pounds per square inch
, - Describe how pressure is transmitted when a force is applied to a confined
liquid. - -Pressure is transmitted equally in all directions.
- What formula expressed the relationship between force, pressure and
area? - -Force equals area times pressure.

inches of Mercury or 1013.2 millibars.
- On a standard day at sea level, what is the value for temperature? - -59
deg. F or 15 deg. C

atmospheric pressure.
- What is the term to describe the ratio between the amount of moisture
actually present in the atmosphere as compared to the amount the air could
hold if it were completely saturated? - -Relative humidity.
- What are the four principle forces acting on an airplane in flight? - -Lift,
drag, thrust, and gravity.
- What is the term that describes the angle between the relative wind and
the chord line of airfoil? - -The Angle of Attack (AOA).
- What are the factors that cause the airplane wing to stall? - -Stall is
caused when the angle of attack exceeds a critical value and the airflow
separates from the upper surface and becomes turbulent.
- What are the principle effects that result from lowering the flaps while in
flight? - -Lift increases, drag increases, and stall speed decreases.
- What is the function of a wing mounted vortex generator? - -Vortex
generators delay or keep the airflow from separating from the upper surface
of a wing during high speed flight.
- How does blade flapping help to compensate for dissymmetry of lift in
helicopter main rotor systems? - -Flapping increases the angle of attack and
lift on the retreating blade and decreases the angle of attack and lift on the
advancing blade.
