acceleration vector

常見例句

雙語例句

• Well, the acceleration vector there will be zero from one.
  加速度矢量爲(wèi)。
• 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?cè)谶@點(diǎn)觀察運(yùn)動(dòng)的軌跡，它的加速度是指曏這個(gè)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(duì)加速度給出一個(gè)嚴(yán)格的定義，加速度,作爲(wèi)一個(gè)矢量,是速度的一堦導(dǎo)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(duì)導(dǎo)數(shù)再求一次導(dǎo),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(yuàn)意的話,我可以把加速度寫成矢量形式

• 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(gè)加速度爲(wèi) a 的質(zhì)點(diǎn),加速度恒定,但 a 是一個(gè)矢量
