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 help in visualizing structures or processes without considering dynamic factors like time or external influences. In contrast to dynamic models, which account for changes and interactions, static models provide a simplified view. They can be physical, like a scale model of a building, or abstract, like a mathematical equation. Static models are valuable for analysis and communication, making complex ideas easier to understand.
