A model toy is a simplistic model or prototype of an object or product with many details removed so that it can be used to explain a mechanism concisely. A model toy is also useful in a description of the whole model. There are two types of model toys: A mathematical toy model and a physical toy model. A mathematical model toy is often made by reducing the number of dimensions and variables, or limiting them to a particular symmetrical shape. Whereas, a physical model toy is analog mechanism that is often used to illustrate an effect in order to make it easier to visualize. An example of physical model toys may be: Orbital mechanics described by two spinning spheres attached by an elastic.
