While a change in the price of the good moves us along the demand curve to a different quantity demanded, a change or shift in demand will cause a different quantity demanded at each and every price. A rightward shift in demand would increase the quantity demanded at all prices compared to the original demand curve. For example, at a price of $40, the quantity demanded would increase from 40 units to 60 units. A helpful hint to remember that more demand shifts the demand curve to the right.
