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

fore Anytime you move the control column fore or aft during flight, you change the angle of attack. 开始学习		przód

coefficient The coefficient of lift is a way to measure lift as it relates to angle of attack. 开始学习		współczynnik
occur Every airplane has an angle of attack where maximum lift occurs. 开始学习		występować
peak As angle of attack increases, CL also increases. This continues to a point where CL peaks. 开始学习		osiagąć szczyt/maksimum
separation 开始学习		oderwanie
disruption Increasing the angle of attack beyond CLmax causes progresive disruption of airflow from the upper surface of the wing. 开始学习		zakłócenie
