Scalar: The quantities which has only magnitude are called scalar quantities, for example distance. Vector: The quantities which has magnitude and direction both are called vector quantities, for example displacement.

Direction angles: These are the angles made by the vector with the positive direction of the axis. Direction cosines: cosines of the direction angles are called direction cosines. Direction ratios: The terms which are proportional to the direction cosines are called direction ratios.
