Answer:a conceptual diagram of a shopping cart (conceptual) alongside a physical model of a bridge (physical), or a conceptual model of an atom (conceptual) and a physical model of a cell (physical). Here are 5 examples of each:Conceptual Models: 1. Entity-Relationship Diagram (ERD): An ERD is a visual representation of the relationships between different entities (like customers, products, orders) in a system, often used in database design. 2. Flowchart:A flowchart uses symbols and arrows to show the steps in a process, like a manufacturing process or a software algorithm. 3. Mental Model:A mental model is a person's internal representation of how something works, such as how they understand how a website is navigated. 4. Conceptual Data Model:This type of model focuses on the high-level concepts and relationships within a system, like the entities "Customer," "Product," and "Order" in an e-commerce system. 5. Conceptual Model of the Solar System:This model would depict the planets orbiting the sun, their relative sizes, and their orbital paths, without necessarily including detailed physical properties. Physical Models: 1. Scale Model of an Airplane: This is a tangible, smaller version of an actual airplane, used for testing aerodynamics or design. 2. Human Organs Model:A 3D model of a human organ, like the heart or lungs, can be used for educational or medical training purposes. 3. Prototype of a New Product:This could be a physical, working version of a new product before it goes into full-scale production. 4. Landform Model:A physical representation of a landscape, like a mountain range or a valley, often used in geography or geology. 5. Building Model:A scaled-down version of a building, used for architectural design or construction planning.
