o What are Newton's laws for gravity? How does it scale with distance and mass? o From Newton's laws, why do different massed bodies fall with same rate (as observed by Galileo)? o What is the "gravitation constant"? What units does it have? o From Newton's laws, how can one derive the necessary speed for a circular orbit?
