What would be the best way to come up with a new model for friction based on my experimental results?(adsbygoogle = window.adsbygoogle || []).push({});

I have been finding the angle at which a block slides, or topples when the angle it is inclined at is increased. This has been done with blocks that are of different heights (towers of building blocks), and the experimental results don't fit the model for friction.

The initial model is coulombs model

(i.e. F=uR)

The model has been used to work out the angle for sliding and toppling with different amounts of blocks, so I decided to take logs of both the number of blocks and the angle, but then couldnt see how to put this back into a new model.

Any ideas how to look at a new model based my experimental results would be appreciated.

Thanks
