Gravity
Gravity (from Latin gravitas , meaning 'weight' [1] ), or gravitation , is a natural phenomenon by which all things with mass or energy —including planets , stars , galaxies , and even light [2] —are brought toward (or gravitate toward) one another. On Earth , gravity gives weight to physical objects , and the Moon 's gravity causes the ocean tides . The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing , forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

Gravity , or gravitation , is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including objects ranging from atoms and photons , to planets and stars . Since energy and mass are equivalent , all forms of energy (including light ) cause gravitation and are under the influence of it. On Earth , gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides . The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects. |

Gravity or gravitation is a natural phenomenon by which all things with mass are brought towards (or 'gravitate' towards) one another including stars, planets, galaxies and even light and sub-atomic particles . Gravity is responsible for the complexity in the universe, by creating spheres of hydrogen — where hydrogen fuses under pressure to form stars — and grouping them into galaxies. Without gravity, the universe would be an uncomplicated one, existing without thermal energy and composed only of equally spaced particles. On Earth, gravity gives weight to physical objects and causes the tides. Gravity has an infinite range, and it cannot be absorbed, transformed, or shielded against. |

Gravitation , or gravity , is the natural phenomenon by which physical bodies appear to attract each other with a force proportional to their masses . It is most commonly experienced as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. The phenomenon of gravitation itself, however, is a byproduct of a more fundamental phenomenon described by general relativity , which suggests that spacetime is curved according to the presence of matter through a yet-to-be discovered mechanism . |

Gravitation , or gravity , is a natural phenomenon by which physical bodies attract with a force proportional to their mass . Gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, and coalesced matter to remain intact, thus accounting for the existence of the Earth , the Sun , and most of the macroscopic objects in the universe . |

Gravitation , or gravity , is a natural phenomenon in which objects with mass attract one another. In everyday life, gravitation is most familiar as the agent that gives weight to objects with mass and causes them to fall to the ground when dropped. Gravitation causes dispersed matter to coalesce, thus accounting for the existence of the Earth , the Sun , and most of the macroscopic objects in the universe . Gravitation is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; for the formation of tides ; for natural convection , by which fluid flow occurs under the influence of a density gradient and gravity; for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena observed on Earth. |

Gravitation is a natural phenomenon by which objects with mass attract one another. [1] In everyday life, gravitation is most commonly thought of as the agency which lends weight to objects with mass. Gravitation compels dispersed matter to coalesce, thus it accounts for the very existence of the Earth , the Sun , and most of the macroscopic objects in the universe . It is responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth, for the formation of tides ; for convection (by which hot fluids rise); for heating the interiors of forming stars and planets to very high temperatures; and for various other phenomena that we observe. Modern physics describes gravitation using the general theory of relativity , in which gravitation is a consequence of the curvature of spacetime which governs the motion of inertial objects. The simpler Newton's law of universal gravitation provides an excellent approximation for most calculations. |

Gravitation is also the reason for the very existence of the Earth , the Sun , and most macroscopic objects in the universe ; without it, matter would not have coalesced into these large masses and life , as we know it, would not exist. |

There have been numerous theories of gravitation starting with the ideas of the Greek philosopher Aristotle in the 4th century BC . He believed that there is no effect without a cause , and therefore no motion without a force . He concluded that all things tried to move toward their proper place in the crystalline spheres of the heavens, and that bodies fell toward the center of the Earth in proportion to their weight . |
