SUMMARY
The Lennard-Jones (L-J) potential equation is defined as V(r) = V(r) repulsive + V(r) attractive, where the ^12 term represents the repulsive force and the ^6 term signifies the attractive force. The attractive force is characterized by a negative gradient, as indicated by the equation F = -∇V. Analyzing the graphs of 1/r^12 and -1/r^6 confirms that the former represents a repulsive potential while the latter illustrates an attractive potential.
