The law of supply states, 'Other things being constant, quantity supplied of a commodity is directly related to the price of commodity', i.e., supply rises when price rises and supply falls when price falls.

When quantity supplied of a commodity changes (rises or falls) due to change in its own price, it is called change in quantity supplied. Graphically it means movement along a supply curve.

When change (rise or fall) in supply is caused by changes in 'factors other than the price', it is merely called change in supply. Graphically it means shift of supply curve.

The supply curve will shift to the right.
