Question		Answer
pull of gravity It is caused by the downward pull of gravity start learning		siła grawitacji
propel Thrust is the forward force which propels the airplane through the air. start learning		napędzać
retarding Opposing thrust is drag, which is a backward, or rerarding, force that limits the speed of the airplane start learning		uwsteczniający
unaccelerated In a straight-and-level, unaccelerated flight, the four forces are in equilibrium. start learning		nieprzyśpieszony
equilibrium start learning		równowaga
magnitude The magnitude of a vector is indicated by the arrow’s length. start learning		wielkość
indicate start learning		wskazać
resultant When two or more forces act on an object at the same time, they combine to create a resultant. start learning		wypadkowy
diagonal When vertical and horizontal forces are applied, the resultant acts in diagonal direction. start learning		przekątna
counteract start learning		przeciwdziałać
to gain start learning		nabierac
to lose start learning		tracic
exert In calm wind conditions, the atmosphere exerts equal pressure on the upper and lower surfaces of the wing. start learning		wywierać
contribute Although several factors contribute to this difference, the shape of the wing is the principal. start learning		przyczynić się
movement of air about the wing start learning		ruch powietrza wokół skrzydła

velocity Bernoulli’s principle explains how air pressure decreases as velocity increases. start learning		prędkość
internal start learning		wewnętrzny
venturi start learning		Venturiego
alter Any surface that alters airflow causes a venturi effect. start learning		zmieniać
curvature The greatest curvature on the upper portion causes air to accelerate as it passes over the wing. start learning		krzywizna

sufficient start learning		wystarczający
incline Wing is attached to the fuselage with the chord line inclined upward at a slight angle. start learning		pochylnia
angle of incidence Angle of incidence is the angle between the chord line and a line parallel to the longitudinal axis of an airplane. start learning		Kąt zaklinowania skrzydła
axis start learning		oś
thus far start learning		dotąd
fore Anytime you move the control column fore or aft during flight, you change the angle of attack. start learning		przód
aft start learning		ku tyłowi
coefficient The coefficient of lift is a way to measure lift as it relates to angle of attack. start learning		współczynnik
occur Every airplane has an angle of attack where maximum lift occurs. start learning		występować
peak As angle of attack increases, CL also increases. This continues to a point where CL peaks. start learning		osiagąć szczyt/maksimum
separation start learning		oderwanie
disruption Increasing the angle of attack beyond CLmax causes progresive disruption of airflow from the upper surface of the wing. start learning		zakłócenie
stall A stall is caused by the separation of airflow from the wing’s upper surface. start learning		przeciągniecie
onset The onset of a stall is gradual. start learning		początek
gradual start learning		stopniowy

cease When drag again equals thrust, the airplane ceases to accelerate and maintains a constant airspeed. start learning		zaprzestać
decelerate When you reduce thrust, the force, the force of drag causes the airplane to decelerate. start learning		zwalniać
moderately start learning		umiarkowanie
parasite drag Parasite drag increases with an increase in airspeed. It consists of all drag not associated with the production of lift. start learning		opór szkodliwy
