I listed a few interesting phenomena; maybe we could try to storyboard and/or animate a single instance as a demonstration?
Here’s my (oh so very rudimentary) concept art:
The idea is to demonstrate a simple case (the transaxial case) of a much broader topic of Coriolis forces in a way with which people can easily relate. We would probably start with the normal case (2nd circle in the image), and then explore walking speeds in different directions (1st and 3rd circle) before moving on to the flying case (4th circle). We could then end with the running case. I expect the topic could be well covered in about 3-5 minutes, using largely looping animations lasting not much longer than 10-20 seconds (rendered from various angles).
There is probably cause to stop midway through the sequence and talk briefly about system design. Some people may wonder whether these changes in weight are noticeable. They are, indeed, very noticeable for smaller systems and lower levels of gravity (think 20% of your weight at walking speeds… even more for running speeds). The effect can be diminished by increasing radius, but does not fade quickly. To drop it to just 5% of weight while walking would require a radius of several hundred kilometers for a system simulating Mars gravity. It might be best to stay away from the math on this for now, instead saving it for animations specific to system design, variable gravity, and tidal forces.
I picture the animation having a standing/walking/flying/running human, a spinning hub-and-spoke “space station”, a background star field (for visual reference), and animated force vector “arrows”, which grow/shrink as the human model’s speed changes. A simple, repeating animation would be needed for each of the visualized speeds. The station’s interior could have a few points of interest (a chair, a desk, a plant, ect.), to show relative movement within the interior (unless that complicates things too much). Displaying the equations and how their input variables and functional outputs change as we transition between different speeds might be good too. It could also be useful to occasionally transition to a simplified “ball and string” model mid-animation, to demonstrate centripetal forces in an inertial reference frame.
Finally, I picture needing two camera modes. One is stationary in reference to the human model (non-inertial reference frame). The other is stationary in reference to the background stars (inertial reference frame). A third, possibly useful, camera would be stationary in reference to the station (also non-inertial). Using some combination of these, it should be possible to demonstrate the principle from the needed variety of perspectives.
@tanner What do you think? Is this within your skills? Or am I being too ambitious here? What else would we need to do this that I haven’t considered?
We could also comment on how the time it takes for the person to make one loop (the period) changes. This number is very demonstrative. In the flying case, for example, the period is infinity (i.e. the person is no longer moving in a circle relative to the background stars, thus no “gravity” is generated).
