How is a rubber band like elasticity? Consider a rubber band. When we think of "elastic," we may think of something that can be stretched How do the ideas of elasticity and responsiveness relate in real life to economics? If you apply pressure or stimulus to a rubber band how much does it stretch? Is it possible to measure the rate of change? Think of Theraband's or resistance bands - some require a lot of pressure to stretch them out (inelastic) while others do not require nearly as much (elastic). A rubber band that increases to 8 inches when stretched out is less responsive (less elastic) to the than a rubber band that expands to 14 inches
