Static models are representations that do not change over time. They are often used in various fields, such as architecture, engineering, and economics, to illustrate concepts or systems at a specific moment. These models can be physical, like scale models of buildings, or digital, like graphs and charts that display data. Unlike dynamic models, which account for changes and interactions over time, static models provide a snapshot of a situation. They help in understanding complex systems by simplifying them into manageable parts, making it easier to analyze and communicate ideas without the influence of time-related variables.
