基本解釋加速度矢量英漢例句雙語例句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(shù)。原聲例句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(shù)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耶魯公開課 - 基礎物理課程節(jié)選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耶魯公開課 - 基礎物理課程節(jié)選I want to consider a particle which has definite acceleration a, a constant one, but a is now a vector.我想考慮一個加速度爲 a 的質(zhì)點,加速度恒定,但 a 是一個矢量耶魯公開課 - 基礎物理課程節(jié)選acceleration vector更多例句詞組短語短語acceleration vector polygon 加速度矢量多邊形rotation acceleration vector 鏇轉(zhuǎn)加速度矢量generalized acceleration vector 廣義加速度矢量Acceleration Vector for Moving Point 動點的加速度矢vector acceleration 矢量加速度acceleration vector更多詞組
