Assignment...
- On the simulation for the earth and the sun, what happens when you increase the size of the sun? What happens when you decrease the size of the sun?
- What happens when you increase the size of the earth and the sun stays the same size?
- On the simulation for the earth and the moon, what happens when you decrease the size of the earth? What happens when you increase the size of the earth? What happens when you increase the size of the moon or decrease the size of the moon?
- Give a quick summary of what these simulations show.
