Gravity Model
The Gravity Model is a concept used to predict and analyze interactions between entities, like people, cities, or countries, based on their sizes and distances. Just like how larger objects exert more gravitational pull in space, larger populations or economies tend to attract more trade or interaction. The model suggests that the closer two entities are to each other, the stronger their interaction will be. For example, two neighboring cities are likely to trade more than two distant ones, and larger cities will exchange more goods and services than smaller ones.

The Gravity Model is a concept used to predict the interaction between two places, such as trade or travel. It suggests that larger locations attract more activity because of their size, while distance decreases interaction. Imagine a pair of magnets: a bigger magnet pulls more strongly and if two magnets are far apart, they attract each other less. In this way, bigger cities or countries engage more with each other than smaller ones, especially if they are close together. The model helps researchers understand patterns of movement and exchange in economics, sociology, and geography.
