** Its SI unit is m/s .
** Its CGS unit is cm/ s .
** It is a scalar quantity (that is , it has only magnitude ).

** The distance covered by a body in a specified direction in an interval of time is called the velocity of the body.
** Its SI unit is m/s due ( in a specifies direction ).
** Its CGS unit is cm/ s due ( in a specifies direction ).
** It is a vector quantity (that is , it has both magnitude and direction ).

Hope it helps !!
