Hey there,
I'm trying to find some information on static friction, particularly extended theories of Amonton's. So far, I've found that Amonton said that static friction is a result of surfaces conforming to each other while not moving. I'm tyring to find recent extensions to this theory, mainly like this: "On the molecular level, it has been extended lately to propose that the intermolecular forces have time to make tiny bonds between molecules of the object with molecules of the surface. These extra forces have to be overcome to start the object moving, causing the static friction to be higher than the kinetic friction." I've done searches on Google, but I can't seem to come up with anything. I find lots of information about the surfaces conforming with each other, but nothing on bonds formed on stationary objects.Thanks!
Edit: By doing further research I am guessing that the bond that forms between the object and the surface would be classified as Dipole-Dipole since this is a relatively weak force but involves neutral molecules?
