Not available (2014-04)
Using this simulation one can: describe the relationship between the Sun, Earth, Moon and space station including orbits and positions. describe the size and distance between the Sun, Earth, Moon and space station. explain how gravity controls the motion of our solar system. - identify the variables that affect the strength of gravity. predict how motion would change if gravity was stronger or weaker.
