Answer:
In the world of science, models can be described as representations of phenomenons which are present on the Earth or in the universe. A model can be an idea, mathematical calculation, equations, visual representation or computational representation etc.
The strength of a model is that it helps to understand the phenomenons of nature easily. It helps us to understand concepts which otherwise would have been very difficult to understand.
The drawback of a model is that if it is wrong, then people will get the wrong idea of a concept.
