Questions and Answers
kinetic (sliding) friction - ANS-results when the surface of one object slides along the
surface of another object.
fluid friction - ANS-is the resistance to an object's motion through a liquid or gas.
Pertains to aviation through drag
rolling friction - ANS-friction that occurs when an object rolls over a surface
static friction - ANS-is what holds an object in one place. Static friction keeps an object
at rest when that object is acted upon by an external force.
4 types of friction - ANS-static, sliding, rolling, fluid
First - ANS-Newton's _____ Law of Motion (Law of Inertia) states that an object will stay
at rest, or in motion at a constant velocity unless acted upon by an unbalanced force,
such as gravity or friction
Second - ANS-Newton's ______ Law of Motion states that when a body is acted upon
by a constant force, its resulting acceleration is inversely proportional to the mass of the
body and directly proportional to the applied force.
Force equals mass times acceleration (F=ma)
Third - ANS-Newton's _____ Law of Motion states that if two objects interact, the force
exerted by the first object on the second object is equal in magnitude and opposite in
direction to the force exerted by the second object on the first object
"For every action there is an equal or opposite reaction"
Universal Gravitation - ANS-Newton's Law of _________ ___________ states that a
particle attracts every other particle in the universe with a force that is directly
proportional to the product of their masses and inversely proportional to the square of
the distance between them.
This illustrates how gravitational force increases with mass and decreases with
distance.
, Bernoulli's Principle - ANS-within a horizontal flow of fluid, points of faster fluid speed
will experience less pressure than points of slower fluid speed.
The curvature of an airplane wing/rotor causes air to pass faster over the top of the wing
(creating a lower pressure area) than under the wing (a higher pressure area)
four forces of flight - ANS-lift, weight, thrust, and drag
empty weight center of gravity - ANS-EWCG
Manufacturer's Empty Weight (MEW) - ANS-Total weight of the aircraft as it was built.
this includes the system operating components
DOS NOT include fuel or fluids
Operating Empty Weight (OEW) - ANS-MEW plus the weight of the crew, fluids,
unusable fuel, and the equipment required for flight.
DOES NOT include usable fuel, baggage or passengers
All-Up Weight (AUW) or Aircraft Gross Weight (AGW) - ANS-Is the aircraft weight at any
given moment during flight. the AUW / AGW decreases as fuel and fluids are consumed
during the operation of the flight.
Maximum Landing Weight (MLW) - ANS-Is the maximum weight limit for landing.
Exceeding this weight may put stress on the landing gear and may require a longer
required landing distance.
Maximum Zero Fuel Weight (MZFW) - ANS-is the permissible weight of an aircraft with
its contents and includes unusable fuel. it excludes and consumable fluids.
Maximum Takeoff Weight (MTOW) - ANS-Aircraft's weight limit for takeoff. Exceeding
this increases the power required for takeoff, lengthens necessary runway and stresses
the structure of the aircraft.
Maximum Ramp Weight (MRW) - ANS-The weight limit for an aircraft to taxied or towed
on the ground.
Flight Envelope - ANS-Encompasses the limits of speed, altitude, and angle of attack
required by any aircraft to maintain a stable flight.
An incorrect combination of these factors may result in a stall
