radius vector
Definition
In physics, radius vector (r) refers to a vector that represents both magnitude and direction from an origin point to another point in space.
Analogy
Imagine you are giving directions to your friend who is lost. You tell them how far they need to go (magnitude) and which way they should turn (direction). The radius vector works similarly by specifying both magnitude and direction from one point to another.
