## Emergence
**Emerges from:** [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [space](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-space.extent), [time](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-time.dimension)

**Through:** The motion moves the thing down in space during time.

**Novel properties:**
- down motion
- no contact
- more motion

## Examples
- An apple drops from a branch in Isaac Newton's garden at Woolsthorpe Manor in 1666. *(physics)*
- The 2008 collapse of Lehman Brothers accelerated as asset prices fell daily during the financial crisis. *(economics)*
