what is the common name for gravitational force
Gravity Gravity, or gravitation
title: Gravity text: and prevents further acceleration. The force of gravity on Earth is the resultant (vector sum) of two forces: (a) The gravitational attraction in accordance with Newton's universal law of gravitation, and (b) the centrifugal force, which results from the choice of an earthbound, rotating frame of reference. The force of gravity is the weakest at the equator because of the centrifugal force caused by the Earth's rotation and because points on the equator are furthest from the center of the Earth. The force of gravity varies with latitude and increases from about 9.780 m/s at the Equator to about 9.832 title: Gravitational acceleration text: Gravitational acceleration In physics, gravitational acceleration is the acceleration on an object caused by the force of gravitation. Neglecting friction such as air resistance, all small bodies accelerate in a gravitational field at the same rate relative to the center of mass. This equality is true regardless of the masses or compositions of the bodies. At different points on Earth, objects fall with an acceleration between and depending on altitude and latitude, with a conventional standard value of exactly 9.80665 m/s (approximately 32.174 ft/s). This does not take into account other effects, such as buoyancy or drag. Newton's law of title: Gravity text: Gravity Gravity (), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—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 starsand for the stars to group together into galaxiesso 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 title: Gravity text: is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass. The most extreme example of this curvature of spacetime is a black hole, from which nothing—not even light—can escape once past the black hole's event horizon. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force which causes any two bodies to be attracted to each other, with the force proportional title: Kilogram-force text: Kilogram-force The kilogram-force (kgf or kg), or kilopond (kp, from Latin "pondus" meaning "weight"), is a gravitational metric unit of force. It is equal to the magnitude of the force exerted on one kilogram of mass in a gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). Therefore, one kilogram-force is by definition equal to . Similarly, a gram-force is , and a milligram-force is . One kilogram-force is approximately 2.204622 pound-force. Kilogram-force is a non-standard unit and is classified in SI Metric System as a unit that is unacceptable for use with SI.
