What is the gravity model ap human geography?

The gravity model in AP Human Geography is a mathematical formula used to predict the movement of people, goods, and information between two places. It is based on the principle that the movement of these entities is influenced by the population size and distance between two locations.

The gravity model states that the amount of interaction between two places is directly proportional to the size of their populations and inversely proportional to the distance between them. In other words, places with larger populations and closer proximity are more likely to interact with each other than places with smaller populations and greater distances.

The gravity model is used by geographers to understand patterns of migration, trade, and communication between different regions. It helps to explain why some cities are more interconnected than others, and why certain regions have greater economic and cultural exchange.

Overall, the gravity model is a useful tool for predicting and analyzing spatial interactions in AP Human Geography, and it helps geographers understand the patterns and relationships between different places on a global scale.
