Stopping time

Here are a few things to try:

• What happens when you increase g?
• The value of g at the surface of the Moon is about 1.6 m/s². Plug that in and compare freefall there with freefall on the Earth.
• Pick a certain positive initial velocity, and run the simulation. What happens if you start with a negative initial velocity of the same megnitude?
