Volume is a scalar quantity because it only has magnitude and no direction. It measures the amount of space occupied by an object or substance.
A vector quantity.
Current density is a vector quantity because it has both magnitude and direction. It represents the flow of electric charge per unit area in a specific direction, as opposed to current which is the total amount of charge flowing through a conductor. The direction of current density indicates the direction in which the charges are moving.
Relative density is a scalar quantity that represents the ratio of the density of a substance to the density of a reference substance (usually water). It does not have direction, so it is considered a scalar.
Velocity is a vector quantity.
