Distinguish between a movement along a given demand curve and a change in demandprovide an example for each?

Answer 1

The change in the demand of a commodity due to change in its price leads to moving the demand curve upward or downward depending upon the change in price. When the price rises, the demand falls. And when the price falls the demand for that commodity rises leading to movement in the demand curve. Shift in the demand curve is the result of the price remaining constant but the demand changing due to several other factors such as, change in fashion, population, etc. Hence at the same price when more is demanded the demand curve shifts to the right. and at the same price when less commodity is demanded it results in the shift of the demand curve to the left.

Answer 2

movement along a demand curve is the change in demand due to change in price where as change in demand curve or shift in demand curve is change in demand due to change in income, other products, community geographical area rather than a change in price.

Answer 3

movement on the curve is simply things going along as expected, like ok I want that and other people do too, so the demand curve is high. A shift occurs when the demand changes, like I found something new and everyone wants that thing now, so the demand for that other thing has shifted because nobody wants it anymore.
