A change in quantity supplied refers to a movement along the existing supply curve, caused by a change in price. On the other hand, a change in supply is a shift of the entire supply curve due to factors such as changes in technology, input prices, or government regulations affecting production. Therefore, the primary difference between the two is the direction of the movement - one is along the curve and the other shifts the curve.
