    Answer:

    Velocity

    Explanation:

    In physics, there are two types of quantity:

    – Scalar quantity: these quantities have a magnitude only, so they don’t have a direction. Examples of scalar quantities are mass, temperature, time…

    – Vector quantity: these quantities have both a magnitude and a direction. Example of vector quantities are velocity, acceleration, force…

    An example of vector quantity is velocity. Velocity is defined as

    v=\frac{\Delta x}{\Delta t}

    where

    \Delta x is the displacement of an object, which is a vector connecting its initial position to its final position of motion

    \Delta t is the time elapsed

    Therefore, velocity has a magnitude and a direction (which is the same as the direction of the displacement). This quantity is used in daily life in many situations, for example when we drive in a car, it is useful to know the velocity at which the car is going.
