Encyclopedia > Gravity field

The gravity field is the field of force, caused by the gravitation of the Earth, and influenced by the Earth rotation, the atmosphere and by geological bodies. In physics, as defined by Asimov, a force is that which can impose a change of velocity on a material body. ... This article covers the physics of gravitation. ...

The field can be described by several observationables like

The last developments of Astronautics has caused a higher interest in the gravity field of other celestial bodies, too - e.g. of the planet Mars and some asteroids like Eris or Ida, and on a theoretical basis also on stars or extreme masses like black holes, and in the theories of cosmology. Gravitation is the tendency of masses to move toward each other. ... Gravimetry is the measurement of gravitational force, weight, or density. ... Geophysics, the study of the earth by quantitative physical methods, especially by seismic reflection and refraction, gravity, magnetic, electrical, electromagnetic, and radioactivity methods. ... An object is in a vertical position when it is aligned in an up-down direction, perpendicular to the horizon. ... The vertical deflections (deflections of the plumb line, astro-geodetic deflections) are important parameters of the local gravity field. ... Mount Cook, a mountain in New Zealand A mountain is a landform that extends above the surrounding terrain in a limited area. ... This article or section should include material from Geodetic datum. ... A geoid is a close representation, physical model, of the figure of the Earth. ... In construction, level (as an adjective) is to horizontal what plumb is to vertical. ... Trigonometry (from the Greek trigonon = three angles and metro = measure) is a branch of mathematics dealing with angles, triangles and trigonometric functions such as sine, cosine and tangent. ... Surveying is concerned with the application of mathematics and physics in obtaining accurate measurements for the determination of the position of points on the Earths surface. ... In physics, a potential is a scalar quantity that can be used to analyze the effects of complicated vectorial forces and similar quantities by means of simple conservation laws. ... Potential theory may be defined as the study of harmonic functions. ... Astronautics is the branch of engineering that deals with machines designed to work outside of Earths atmosphere, whether manned or unmanned. ... Mars, with polar ice caps visible. ... An asteroid is a small, solid object in our Solar System, orbiting the Sun. ... The Pleiades star cluster A star is any massive gaseous body in outer space, just like the Sun. ... An artists impression of a black hole with a closely orbiting companion star that exceeds its Roche limit. ... Look up Cosmology in Wiktionary, the free dictionary For the jazz band, see: Cosmology (band) Cosmology, from the Greek: κοσμολογία (cosmologia, κόσμος (cosmos) world + λογια (logia) discourse) is the study of the universe in its totality and by extension mans place in it. ...

This field may be thought of as a "clustering" of the HF in the vicinity of matter, or as a local polarizing effect that matter would have on the HF.
The "hypothetical" field described earlier as a clustering of the HF in the vicinity of matter is merely the prosaic gravity field of everyday experience.
In conclusion, field centrality requires that electromagnetic waves whose source is put in uniform motion, being a combination of electric and magnetic fields, should move through space with the same convective flow which describes the motion of their individual constituent fields in isolation.
