This formula assumes a continuum model and smooth surfaces. Observe that the ratio is inversely proportional to the side 'S'. Therefore, smaller the side, bigger the ratio, and bigger the side, smaller the ratio. As the cube gets smaller, adhesive forces increasingly dominate the gravity forces, and thus the smaller sugar cubes stick to us better than the large ones. Forces and Scale Interactions between objects, in the universe as we understand it, are governed by four major forces.
Gravity acts between all bodies with mass.
It is probably the most familiar force at the macroscale and cosmological scale. Yet, we know so little about it, especially at the smallest scale, where it is the weakest of all of the forces. It is always attractive. It is a long-ranged force that is especially dominant at the cosmological and macroscopic world. Electromagnetic Force is responsible for the forces that control atomic structure, chemical reactions and all electromagnetic phenomena.
