Vector

Explanation:

Vector is a quantity that shows the direction or path through which a body travels with as it changes position.

As body travels, the direction sometimes changes and this is described by the vector of the body.

Velocity is a vector quantity that describes the displacement per unit of time of a body.

Speed is a scalar that deals with the distance covered per time

So, a vector specifies the magnitude of a physical quantity and also the direction through which it travels.
