Answer to U The Lennard-Jones potential is a potential energy function that describes the interaction between two neutral molecule

I don't know the history behind this convention, but it certainly dictates that test particles in the force field move from higher to lower potentials. History of intermolecular and surface forces. Van der Waals equation of state.

The Lennard-Jones potential is a relatively-simple mathematical model describing the potential energy $V_{LJ}$ between a pair of neutral atoms as a function of both the distance in units of radii where the potential is zero $\sigma$ (sigma) and the maximum depth of the potential well $\varepsilon$ (epsilon).

Apart from being an important model in itself, the Lennard-Jones potential frequently forms one of 'building blocks' of many force fields. The Lennard-Jones potential (also referred to as the L-J potential, 6-12 potential or, less commonly, 12-6 potential) is a simple mathematical model that represents this behavior. It was proposed in 1924 by John Lennard-Jones. The L-J potential is of the form This extends the work done by Lennard-Jones and Ingham in 1924, Corner in 1939, and Wallace in 1965.

The Lennard–Jones potential (LJ) is a simple pair potential that can accurately model weak van der Waals bonds between noble gases, yielding reliable bond energies and bond lengths (Lennard–Jones 1924). The LJ has the form (1) ɛ V LJ (r) = 4 ɛ [ (σ γ) 12 − (σ γ) 6] Proposed by Sir John Edward Lennard-Jones, the Lennard-Jones potential describes the potential energy of interaction between two non-bonding atoms or molecules based on their distance of separation. The potential equation accounts for the difference between attractive forces ( dipole-dipole , dipole-induced dipole, and London interactions ) and repulsive forces. The Lennard-Jones potential is a relatively-simple mathematical model describing the potential energy $V_{LJ}$ between a pair of neutral atoms as a function of both the distance in units of radii where the potential is zero $\sigma$ (sigma) and the maximum depth of the potential The Lennard-Jones Potential.
