When the shape of a wing creates more lift from the air passing around it than it does drag (air resistance), an aircraft will fly.
当鱼鳍的形状通过流动的空气产生比其(空气)阻力更多的升力时，飞行物便能飞翔。
Disrupted air, where the flow 'separates' from the body, creates turbulence which creates drag - which slows the car down.
与身体分隔的紊乱的空气产生涡流进而造成空气阻力，使得车速下降。
If there were no air drag — remember we dropped - an apple early on from three meters — it will hit the floor at about 780 milliseconds.
如果没有空气阻力-，记得早些时候，我们从3m处扔苹果-，在780毫秒以后，会掉到地上。
An ominous air emits from the chalice, gripping the hearts of those who peer at it as if determined to drag them to the world of the dead.
一股不祥的气息从这个圣杯中散发出来，抓住那些窥视它的人们的心，仿佛下定决心要将他们拽入死者的世界一般。
The analysis of aerodynamic force data shows that differ front shape is very important to aerodynamic force. For example, coach model air drag coefficient can be lowed to 0.5759 from 0.7509.
试验数据分析结果表明，不同客车前部造型对气动力影响非常显著，如通过改善造型可使空气阻力系数由0.7509降为0.5759。
Dissociation and ionization of air bring on lower drag coefficients of the orbiter than that obtained from perfect gas model, while the location of pressure center moves forward.
空气的离解和电离导致轨道器的阻力系数比完全气体计算值低，压心位置前移。
