(2016). To understand a gravity model definition, you should understand that it is called the gravity model because it is related to Isaac Newton’s Law of Gravitation, … Gravity model — Gravity models are used in various social sciences to predict and describe certain behaviors that mimic gravitational interaction as described in Isaac Newton s law of gravity. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Journal of Geography, 76, 5, 179-82, Sep/Oct 77 The authors suggest ways in which the gravity model can be used in high school geography classes. Gravity like representations have been applied in a wide variety of contexts, such as migration, commodity flows, traffic flows, commuting, and evaluating boundaries between market areas. To make this method as accessible as possible, we will take a step-by-step approach to understand the components of the formula and how to calculate it for the example data, which we will begin to compile in the next step.
