PHY.5:3 - Forces
| Force | Tension |
|---|
| Resolution and usable explanation | More resolved variables can expose a mechanism while making the relevant consequence harder to obtain. |
| Scale separation and coupling | A fast process can relax quickly yet continue to alter the slow behavior through its response. |
| Mean response and variability | An average can settle one question while missing fluctuations that determine another. |
| Local approximation and changed conditions | A useful omission can fail at a boundary, during preparation or after the work changes the forcing. |
| Available grounds and further inquiry | Existing laws and bounds may settle the choice; an unresolved physical premise can sometimes justify a targeted comparison. |
