# stop (action)

to be a change that motion interacts with limit and ends

- Computed level: L15 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: all  ·  Arena: stop

## Emergence
**Emerges from:** [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [boundary](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-boundary.limit), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [interaction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interaction.process), [interacting](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interacting.social), [limit](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-limit.boundary)

**Through:** motion interacts with limit through mutual change, resulting in cessation of movement

**Novel properties:**
- cessation of movement
- mutual resistance
- final displacement
