In liquid water, this twisting leads to molecular friction and heating.

Yet the molecular friction is essential somewhere.

The molecular friction between two components is proportional to their difference in speed and their mole fractions.

Molecular friction rarely upsets the dominant balances (geostroppic and hydrostatic) in the ocean.

The basic assumption of the theory is that a deviation from equilibrium between the molecular friction and thermodynamic interactions leads to the diffusion flux.

Drifting of the tip is also seen due to piezo hysteresis, which causes displacement due to molecular friction and polarization effects due to the applied electric field.

He can also scale walls using a combination of his sharp claws and micro-scales on his hands and feet that create molecular friction like those of a gecko lizard.
