A model is a simplified representation or example of something that helps us understand how it works. In science, a model shows how a system functions (like the solar system model). In fashion, a model is a person who wears clothes to display them. In academics, a model can be a sample essay or structure. Models are used in many subjects like math, engineering, and business to test/ ideas before applying them in real situations. A model doesn’t show every detail but focuses on the most important parts to make learning or designing easier.
