# Motion notes

## Summary

For uniform motion, divide distance by elapsed time.[^source]

## Data and formula

| Distance (m) | Time (s) | Speed (m/s) |
| --- | --- | --- |
| 20 | 4 | 5 |

$$
v = \frac{d}{t} = \frac{20}{4} = 5
$$

The unit is metres per second, not metres.[^unit]

[^source]: These numbers are self-authored teaching examples, not experimental measurements.
[^unit]: Speed uses distance divided by time.
