What must a vector quantity have
that a scalar quantity cannot have? (A) A direction, (B) a
magnitude.
All physical quantities like
acceleration or distance or force can be divided into two categories. Both scalar and vector quantities
have a magnitude, but vectors have something scalars do not: a direction. This is how we define the
difference between scalars and vectors. A direction is something a vector
must have and a scalar cannot have. We choose answer option (A).
