Scientific models are used to study and understand objects, events, and phenomena.

If the model is smaller or bigger than the actual object, it is referred to as a scale model 

A mathematical model is sometimes referred to as a data model

A physical model can be a scaled replica of an object.  

A computer model utilizes physical materials to provide a visual representation of abstract concept.

Physical model are highly accurate as they closely resemble the objects or systems they are trying to represent.   

A mathematical model is a representation of real-world situations using mathematical equations, data, graphs and diagrams.

Computer models allow scientists  to improve their design.

Pilot train for many hours using real planes  before they can fly in a flight simulator.

All models are quite helpful and have no limitations.
