Here are some questions to answer when playing with the simulation.

1. What are all the possible combinations of acceleration?

2. Which 2 of the 4 accelerations point in the same direction?

3. Which 2 of the 4 accelerations point in opposite directions?

4. When centripetal and coriolis acceleration are present, or radial, centripetal and coriolis, or tangential, centripetal, and coriolis, or all four, the position trace forms a spiral.  Which combination of accelerations would cause the radius of the spiral to increase the fastest?
