Labels:text | screenshot OCR: SIZE The gravitational pull between a sphere and an object on the sphere's surface depends on the size of the sphere. The amount of pull is determined by the sphere's radius [distance to its center(centre)] multiplied by itself. An increase in the radius produces a decrease in the pull. The above relationship is true when the mass of the sphere is evenly distributed throughout the sphere. For simplicity. this simulation treats the earth and all the other spheres on which the person "stands" as if their masses were Evenly distributed.
