entity
A model is similar to the real object it represents by capturing its key features and characteristics. However, a model is usually a simplified version of the real object, focusing on specific aspects or dimensions for a particular purpose. Models are used to understand, analyze, or predict the behavior of the real object in a more manageable way.
A model is similar to the real object it represents in that it is a simplified representation that captures essential features or characteristics of the real object. Models are used for understanding, analysis, and prediction, and they provide a framework to study the behavior or properties of the real object in a controlled or simulated environment.
An entity refers to a distinct element with unique identity or characteristics, such as a person or organization. A cartographic object, on the other hand, represents a geographic feature or object on a map, like a road or building. In essence, entities are real-world entities while cartographic objects are representations of physical elements on a map.
Instantaneous speed is indicated by a speedometer in a vehicle or by a GPS device that shows real-time speed. It represents the speed of an object at a specific moment in time.
Concave mirror is used to a real image as big as real object. If the object is placed at center of curvature , then real image is formed at the same center of curvature.

The model is similar to the real object because of how it is three-dimensional.

Entity could be anything which is perceived to have a distinct and separate existence (living or non-living). The basic object that the ER model represents is an entity. An entity is a thing in the real world with an independent existence. An entity may be an object with a physical existence or it may be an object with a conceptual existence. Each entity has attributes- the particular properties that describe it. A particular entity will have a value for each of its attributes.
In this context, an "object" refers to a specific instance of a class in programming. It represents a real-world entity with its own attributes and behaviors.
A scale represents the relationship between a model and the actual measurement if the real object.
In data modeling, an entity represents a real-world concept or thing, while an object is a specific instance of that entity. Entities are more abstract and general, while objects are concrete and specific.
Globe
It usually represents a part of a whole.
If you asking where you'd find them in the real world - Binoculars and telescopes are two examples.
Table is where the data is stored and in a well designed schema a table represents some real world object such as CUSTOMER, ORDER, etc., Now the real world objects have relationships. For example, a CUSTOMER has many ORDERS. To represent this relationship a database relationship was invented.
A class is a blueprint or a detailed description of a real-world object. An object is an instantiation of a class into memory.
