Analogy in teaching is the use of known physical phenomena and processes with unknown physical phenomena and processes compared to find out their commonalities and similarities, and based on that, some of the characteristics of new knowledge and laws A analogy to understand the forces between molecules The composition of the material there is a gravitational and repulsive force between molecules, under what circumstances show repulsive? Under what circumstances showed gravity? As shown in Figure 1, the two fists that two Molecule, when in two graphs
