Very confusing photogrammetry: pixel, scale and accuracy

As we talk about the specifications of Aerial photo then we need to assign the following:

- Cell size or pixel (for example: 10cmx10cm)
- Scale (for example 1:1000)
- Accuracy (error)

But I couldn???t know whether these specifications are linked to one another!
Is there an empirical equation that calculates these specifications?

If we get an aerial photo, then we can know the cell size only, but what???s about the scale and the accuracy?

Thank you in advance,

Regards

Jamal
