vector & scalar

                                                             Scalar & Vector


           The difference between scalar and vector is that a vector is a quantity showing the direction and the amount of something. 

Vector - example; the velocity of a car is 3 m/s to the left. This description of the velocity is showing the direction (left) and the amount of something ( velocity). 

            The scalar is also showing the amount of something but without a direction. 
         
         example;  the velocity of the car is 3 m/s. This description of the velocity is showing the amount of something ( velocity).
