2D Motion - Comparing the path of projectiles on Earth and Mars Imagine you are repeating the "Land the Rover" experiment on Mars. How would the experiment differ than the one done on Earth? You'd have to include a discussion of the how HLPs behave on Earth (more "gravity" and lots of air friction) vs Mars (less "gravity" and hardly any air friction). Include, at least, a set of graph stacks to help in the comparison.

Forces/2D Motion - HLP and the ISS
Revisit the physics of the ISS...how did it get into near-Earth orbit? Why are astronauts "weightless"? How is the ISS really like a HLP? How did Isaac Newton usher in the concept of launching satellites with his "Newton's Cannon" thought experiment? Address the physics of the ISS through the lens of 2D Motion and Forces.
