Which term describes a physical representation of an object; prototypes and appearance models are examples?

• A. Model
• B. Scale Model
• C. Physical Model
• D. Annotate

Answer: (C)

A physical model is a tangible representation of an object used to study its size, shape, and how it might work or look. Prototypes are physical, often functional versions built to test performance, and appearance models are physical forms crafted to show surface details and visual appeal. Both exist as real objects you can touch and inspect, which is what makes them physical models. A generic model could be mental or digital, not necessarily a physical object, and a scale model is a specific type of physical model that is reduced or enlarged in size. Annotate is about adding notes, not creating a representation. So the best term for a tangible representation with prototypes and appearance models as examples is physical model.
