the universe's way of reminding you that speed is boring but change is everything
means The rate at which something speeds up, slows down, or changes direction over time.
from From Latin acceleratio, built on accelerare 'to hasten' — itself ad- 'toward' plus celer 'swift,' the same celer that gallops through 'celerity.' English took the noun in the 16th century, but it was Newton and the calculus crowd who gave it teeth, fixing it as the rate of change of velocity rather than just a fancy word for hurrying.
- feels like force
- You feel acceleration, never velocity — cars don't fix this
- gravity is faking
- Einstein proved gravity is just acceleration in disguise
- brutal units
- Measured in meters per second per second, stacked
- fighter pilots
- Pull too many g's and blood drains, vision blacks out
- zero to oblivion
- A sneeze accelerates roughly 10 g's of pure expulsion
