现在我们都知道,如果没有空气的阻力,重的物体和轻的物体垂直下落的速度是一样的。
As we know now, heavy objects and light objects fall at the same speed unless air holds them back.
失速,用相对通俗的语言可以解释为:飞机失去了升力,然后在重力的作用下做面向地面的垂直运动。在训练中,飞机垂直下落的短短的时间很让我回味哦。
Explain the stall in simple words is airplane lose lift and drop by gravity. In the training, the short time that the airplane drops is so exciting.
