A class compares gravity using two scale models: • Solar system model: A small asteroid passes near Earth and its path bends slightly. • Galaxy model: The Milky Way's gravity keeps billions of stars, including the Sun, moving in long-term orbits around the galactic center. How does gravity's effect change with scale, based on these models?
