6. VECTORS AND SCALARS

Scalar Quantities: 

Scalar quantities are those quantities which have only magnitude but no direction.

Examples: Mass, length, density, volume, energy, temperature, electric charge, current, electric potential etc.

Vector Quantities: 

Vector quantities are those quantities which have both magnitude as well as direction.

Examples: Displacement, velocity, acceleration, force, electric intensity, magnetic intensity etc.
