Gravity force simulation answer key A glacier is a large accumulation of many years of snow, transformed into ice. Newton's "law" of gravity is a mathematical description of the way bodies are observed to attract one another, based on many scientific experiments and observations. NASA's Gravity Recovery And Climate GRAVITATIONAL PULL See Gravity GRAVITY The force of attraction between two objects which is influenced by the mass of the two objects and the distance between the two objects. Gravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. Gravity is the field around physical bodies, such as planets, that draws objects toward its center. 'Dark matter' theory suggests that a huge amount of dark (invisible to direct observation) matter, interacting gravitationally with the normal, visible matter in the universe, exists. Glaciers, also known as “rivers of ice,” actually flow. The gravitational equation says that the force of gravity is proportional to the product of the two masses (m 1 and m 2), and inversely proportional to the square of the distance (r) between their centers of mass. This solid crystalline material deforms (changes) and moves.
