Since larger places attract people, ideas, and commodities more than smaller places and places closer together have a greater attraction, the gravity model incorporates these two features. AP Human Geography Chapter 10: Agriculture. Sending industrial processes out for external production. Some prefer to use the functional distance between cities instead of the actual distance. For decades, social scientists have been using a modified version of Isaac Newton's Law of Gravitation to predict the movement of people, information, and commodities between cities and even continents. Spyman stated that Eurasia's rimland, the coastal areas, is the key to controlling the World Island. The gravity model can also be used to compare the gravitational attraction between two continents, two countries, two states, two counties, or even two neighborhoods within the same city. Agricultural Geography, Political Geography…) This type of model is used in urban geography. ronit_barman1. It is based on Newton's universal law of gravitation, which measured the attraction of two objects based on their mass and distance. Gravity. Based on the idea that certain types of political and economic relations (especially colonialism) between countries and regions of the world have created arrangements that both control and limit the extent to which regions can develop, Three Main Sectors are :Primary, Secondary and Tertiary and it describes the main areas at which people work in the economy, The Increase in efficiency of production as the number of goods being produced increases. The functional distance can be the driving distance or can even be flight time between cities. Person who developed the model: (Who, Where, When, How) The gravity model was created by Ernst Georg Ravenstein, in London, in the late 1800’s. Newton's law states that: "Any two bodies attract one another with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.
