位置向量
Sign in to saveAlso known as location vector, radius vector, position
vector representing the position of a point with respect to a given origin and axes
A position vector is a mathematical tool that describes where a point is located in space by measuring its distance and direction from a fixed starting point called the origin. It's useful because it provides a precise, standardized way to specify locations and track how objects move in physics, engineering, and other fields.

位置向量（position vector，location vector，radius vector）又稱向徑、矢徑、位矢，是几何学中用来表示空间裡某质点或物体相对于某的“几何位置”的向量。 設定一坐标系，參考这坐标系，质点或物体的坐标，就是相对于這坐标系的原点的位置向量。在运动学裏，位置向量是描述质点运动的基本参量，是一个向量：有大小，也有方向。
