Vector Quantity is defined as which quantity has both direction and magnitude.
It can be represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude.
Although, it does not have any position. For example, Acceleration, Displacement, and Velocity are Vector Quantities, while Speed of the magnitude of Velocity, Mass, and Time are Scalars Quantity.
The Measurement of the Increase or Decrease in the Medium of the temperature is a Vector Quantity. But, the Measurement of the Medium’s Temperature is a Scalar Quantity.
​Force and displacement are vector quantities (they have both magnitude and direction) and the dot product of two vector quantites always gives a scalar quantity. So work has only magnitude but not direction.
