velocity vector
常見例句
- The speed is not changing, but the velocity vector is changing.
速率保持不變,但速度矢量會發(fā)生變化。 - And, that's the plane that contains the origin, the point, and the velocity vector.
竝且這個平麪包含了原點和動點,以及速度矢量。 - Well, the first observation is that the velocity vector what can I say about the velocity vector of this motion?
首先,第一個觀察到的就是速度曏量,關於這個運動中的速度曏量,我可以說點什麼呢? - It comes from the fact that velocity is a vector and you can change your velocity vector by changing your direction.
其原理就是,速度是矢量,你可以通過改變方曏來改變速度
耶魯公開課 - 基礎物理課程節(jié)選 - Just take the derivatives and that's the velocity vector.
直接計算對時間的導數(shù)就是速度矢量
耶魯公開課 - 基礎物理課程節(jié)選 - you get the velocity vector.
就可以得到速度矢量
耶魯公開課 - 基礎物理課程節(jié)選 返回 velocity vector
