In addition to the rotational effects produced by gravitation, real bodies are elastic or fluid, not rigid. Gravitation then produces tidal effects, which include alteration of orbits and rates of rotation, mechanical stress, a tendency for bodies to become spherical or ellipsoidal, and heat generation due to friction. |

Bodies with a uniform, or spherically symmetrical distribution of mass can be treated as particles with all their mass concentrated at the center. This can be mathematically proven, although I do not have the details.
This includes many bodies of interest. These can be examined using laws of calculus.

Other areas of physics including thermodynamics, electromagnetism, relativity theory, quantym theory, and the structure of matter can be connected. Other areas of mechanics including particle mechanics, rigid body mechanics, nonrigid mechanics, and other areas of gravitation can be connected. Other sciences including other areas of chemistry, astronomy, earth science, and biology can be related to this study. |

Personal studies including studies of the human body, psychology, and biography can be connected. Anthropology including social foundations, demography, physical anthropology, human ecology, human geography, and particular groups can be connected. Culture including material culture, conceptual culture, and behavioral culture will be significant. Connections to institutions, sociology, and history will be developed as the site expands. |
