I was watching a SciFi tv show where large objects had an outer speed limit of 18000 kph and that got me wondering what things in everyday life are faster than even 500 kph.
I know bullets can be fast, but they are not exactly everyday life (at least in my life).
I included mass for obvious relativistic reasons.
Can’t find any solid numbers on it, but the micromirrors on a DLP projector are really fast. They rotate 10 degrees or so back and forth something like 1024 times for each color channel for each frame at 60fps.
I’d love to see the acceleration calculations for them.
Tiny masses but insane acceleration.
