[QUOTE="DrClaude, post: 6855964, member: 461323"] Ordinary matter is made of protons, neutrons, and electrons. The interaction between atoms or molecules is due the the Coulomb interaction between the protons in the nuclei and the electrons (including nucleus-nucleus and electron-electron interactions). It is in that sense that it is ultimately electromagnetic interaction. (To be exact, one should consider also quantum mechanics spin, but the resulting interaction will also be of a magnetic nature.) There is also gravitational interaction between atoms and molecules, so there is gravitational potential energy, but it is negligible in this case. [/QUOTE]
