OK, if I'm moving in the plane, then position and velocity are in there.
如果在平面上运动,那么位置和速度也会在这个平面上。
Pulling up hard, Stricklin was trying to get the plane into a position in which he just might survive an ejection and still spare the crowd below.
就这样,斯特里克林拼命拉升着飞机,尽量让飞机进入一个既有利于自己活着弹射出去,又能够拯救下面的观众的位置。
So, if you just look at the position vector, and the velocity vector for any motion at any given time, then together, they determine some plane.
如果你看一下任何时刻运动时的,位置矢量和速度矢量,它们决定了某个平面。
I think it's clear, the position of the object with respect to the ground, this vector is the same as the position of the object with respect to the plane, plus the position of the plane with respect to the ground.
我觉得很明显,物体相对于地面的位置,这个矢量等于,物体相对于平面的位置矢量,加上物体相对于地面的位置矢量
