Is the physics on the double pendulum accurate. I understand with the conservation of angular momentum and shrinking the moment of inertia it could look like that intellectually, but my instinctive self is unsure.
- nstart 5y agoIt’s not. Increase the duration to 20,000 and you see a classic gaming bug of the momentum going haywire eventually. Unsure if it’s anything to do with the environment or the coding. On mobile so can’t really analyze it.
- red_trumpet 5y agoWell, even if the math is correct, the simulation will be lossy if one works with finite precision. And because of the chaotic nature of the double pendulum, small errors will eventually add up to big deviations.
