# fast (speed)

a change where a thing moves a large amount of distance in a short amount of time

- Computed level: L9 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [lot](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-lot.quantity), [short](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-short.length)

**Through:** motion occurs across a large distance within a short span of time

**Novel properties:**
- rate of motion
- high velocity
- temporal efficiency of movement

## Examples
- The Parker Solar Probe reached 692,000 km/h during its close approach to the Sun in 2023. *(physics)*
- Usain Bolt ran 100 meters in 9.58 seconds at the 2009 World Championships in Berlin. *(biology)*
- Google's TPU v4 processes AI training tasks 2.5 times faster than its predecessor in real-world benchmarks. *(computing)*
