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.
Satellites are visible and move at some km per second. Pretty fast
Inside the atmosphere anything faster than some hundreds km/h get so much drag that they either are extremely small (bullets) or extremely powerful (planes, maglev trains)
Are we observing them moving, or are they stationary and we are the ones moving? dramatic dun-dun-duuuunnnn
(kinda joke kinda serious)
You’re moving at about 700 m/s while sitting in your couch, according to Earth’s rotation. So if the plane goes west at max speed, it would be 1400 m/s faster than going west.
The answer is yes, depending on your frame of reference.
Everything in the Universe is moving.
