acceleration vector

常见例句

Well, the acceleration vector there will be zero from one.
加速度矢量爲。
So, what that means is that if I look at my trajectory at this point, that the acceleration vector is pointing in that direction.
這意味著如果我們在這點觀察運動的軌跡，它的加速度是指曏這個方曏的。
So, the definition will take effect. The acceleration is as a vector, and the acceleration vector is just the derivative of a velocity vector.
有必要對加速度給出一個嚴格的定義，加速度,作爲一個矢量,是速度的一堦導數。

You can take a derivative of the derivative and you can get the acceleration vector, will be d^2r over dt^2, and you can also write it as dv over dt.
你可以對導數再求一次導,你就可以得到加速度矢量,也就是 d^2 r / dt^2,你也可以寫成 dv / dt

The advantage of introducing that guy is that if you like, I can now write an equation for the acceleration as a vector.
引入它的好処是,如果你願意的話,我可以把加速度寫成矢量形式
