Movement along the supply curve is defined as the graphical representation of the change in the supply of any commodity due to the change in its own price, other things remaining constant. This condition is known as an extension of supply. It can be graphically shown by the movement from a point to another point of the same supply curve.
The change in the supply curve other than the price determinant is said to be the shift in the supply curve. A shift in supply curve occurs when the producers are willing to offer more or less of a commodity due to the change in other determinants of supply except for the price. In other words, it occurs when the supply of goods and services changes even when the price does not change.
