The problem is of e.g. a larger spherical type thing happily traveling along at a fixed velocity but with a smaller (e.g. 10x smaller by diameter) sphere adhered to the surface. This large/small pair now hits a surface.

What is the likelihood of detachment based on? I am thinking it is a function of the mass of the smaller particle and the deceleration of the combo pair as it hits the wall (i.e. if the F=ma in this scenario exceeds the adhesion force then the smaller thing detaches?)

Now, keep the smaller sphere the same size but increase the larger sphere (lets assume the same force of adhesion between the pair to keep it simple). If traveling at the same velocity as before it seems like there should be a greater chance of detachment, but is this because of momentum exchange? As you can see my Physics here is shocking!

If someone could sort out this basic issue first I'd then like to expand slightly.

Thanks!
