What is Vector and Scalar Quantity? What are some examples of vector quantities? Scalar product, also sometimes known as a dot product, is the product of two vectors that return a single numb A quantity with magnitude but no direction is defined as a scalar quant Scalar quantities cannot be combined together, whereas vectors can. On the other hand, a quantity which has both magnitude and direction is known as a vector quantity. Vector Quantities: Vector quantities refer to the physical quantities characterized by the presence of both magnitude as well as direction. Vector is a measurement that refers to both the magnitude of the unit and the direction of the movement the unit has taken. These quantities have magnitude and direction but they are scalar. It doesn't include displacement or speed; the scalar quantity of distance only discusses how much ground was covered. . But distance represents only, Ans: It is scalar.
