a press of matter that results in a change in motion

- Status: review  ·  Domain: everyday  ·  Arena: force

## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [interaction](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-interaction.process), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [motion](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-motion.movement), [press](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-press.force)

**Through:** when matter interacts through a press, it produces a change in motion

**Novel properties:**
- directed transfer of motion
- contact-mediated acceleration
- resistance to displacement

## Examples
- The 2011 Tohoku earthquake shifted the Earth's axis and moved Japan's main island by 2.4 meters due to tectonic plate pressure. *(geophysics)*
- A hydraulic press exerts 500 tons of force to stamp car chassis at the Tesla Fremont Factory. *(engineering)*
- Myosin molecules in human muscle fibers generate piconewton-scale forces to slide actin filaments during contraction. *(biology)*
