Rigid Body Celestial Mechanics


Spherical bodies with a uniform distribution of mass can be treated as if all the mass were concentrated at the center. However, this is not the case for most real bodies. Gravitation can thus produce rotational forces on extended bodies.	Sapience Home Site Map About Sapience Science Physics Mechanics Gravitation

Spherical bodies with a uniform distribution of mass can be treated as if all the mass were concentrated at the center. However, this is not the case for most real bodies. Gravitation can thus produce rotational forces on extended bodies.

Spherical bodies

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.

Symmetric bodies

This includes many bodies of interest. These can be examined using laws of calculus.

Irregular bodies

This includes many bodies of interest, but the effects of gravitational forces can be quite complicated.


Other sciences including chemistry, astronomy, earth science, and biology principally demonstrate applications. Other areas of physics including thermodynamics, electromagnetism, relativity theory, quantum theory, and structure of matter are fairly important. Other areas of mechanics including particle mechanics, rigid body mechanics, nonrigid mechanics, and other areas of gravitation will be useful.	Sapience Home
Personal studies including the human body, psychology, and biography are mostly rather weakly connected. Anthropology including social foundations, demography, physical anthropology, human ecology, human geography, and particular groups are also rather weakly connected. Culture including material culture, conceptual culture, and behavioral culture is more strongly connected. Institutions including families, education, economics, government, and religion can be connected. Connections to sociology, and history will be developed as the site expands.
