The law of demand states that as the price decreases, the quantity demanded will increase. A change in quantity demanded occurs when the price of the product changes. This means that you move point-to-point along the demand curve.
A change in demand refers to a shift of the entire demand curve. This is caused by a change in the determinants of demand.
Change in quantity demanded: point-to-point movement along demand curve
Change in demand: shift of the demand curve
