Lennard-Jones potential

Lennard-Jones Potential (LJ) is a mathematical equation used to calculate the force between two particles that are close together. It is named after two scientists, John Lennard-Jones and Eugene Wigner, who developed the equation in the early 1900's. The equation says that the force between two particles follows an inverse-square law, which means that the distance between the particles affects how strongly they are attracted to each other. For example, if two particles are very close together, they will be attracted to each other much more strongly than if they are far apart. LJ helps scientists understand and predict how particles interact with each other in many different situations, from the behavior of gases to the bonds between atoms.
