So, the definition will take effect. The acceleration is as a vector, and the acceleration vector is just the derivative of a velocity vector. 有必要对加速度给出一个严格的定义,加速度,作为一个矢量,是速度的一阶导数。 - 2
So, the velocity vector is the derivative of a position vector with respect to time. - 3
And, the way we can get it, so, it's called usually V, so, V here stands for velocity more than for vector. And, you just get it by taking the derivative of a position vector with respect to time. 根据它的原理,我们通常用v表示,这里的V更代表速率而不是矢量,你能通过,对一个关于时间的位置向量求导得到它。
