and therefore, when i solve the equations, va i get both vp and va because those are the situations that the velocity vector is perpendicular to the position vector.
因此,当我解方程时,分别得到vp和,因为速度向量,垂直于方向向量。
speed is the magnitude of the velocity vector and the speed, therefore, always has a positive value.
速率是速度矢量的大小,因此速率一般,都是正值。
this acceleration that is necessary to make the change in the velocity vector is always pointing towards the center of the circle.

this expression not only contains the term of dot product of velocity vector and temperature gradient, but also contains the dot product of velocity vector and the pressure gradient.
该式不仅含速度矢量与温度梯度矢量的点积项,还含有速度矢量与压力梯度矢量的点积项。
so, maybe if i actually stated directly that way, see, i'm just saying the velocity vector has a length and a direction.
也许我们可以这样理解,看,我说过速度矢量有模长和方向。

more precisely curl v measures twice the angular velocity, or maybe i should say the angular velocity vector because it also includes the axis of rotation.
更精确地,curv,v值为角速度的2倍,或许我应该说,角速度向量,因为它带有旋转轴。
so, even if the speed is constant, that means, even if a length of the velocity vector stays the same, the velocity vector can still rotate.
因此即使速率不变,也就是说速度矢量的的大小不变,但它的方向可以做旋转。
well, the first observation is that the velocity vector what can i say about the velocity vector of this motion?
