WebScientists call this shape an “oblate spheroid”. Earth only has one natural satellite — the Moon! Where Did the Word Earth Come From. The word Earth has been around for over 1,000 years. It means “the ground” and is German. While the word is over 1,000 years old, it was not used as the name for our planet until the 16th century. ... WebBecause Earth is an oblate spheroid rather than a perfect sphere, it is wider at the equator and narrower toward each pole. Therefore, the bottom of Litke Deep, which is near the North Pole, is closer to Earth's centre than the bottom of Challenger Deep is; the latter is 14.7268 km (48,316.3 ft) further, at 6,366.4311 km (3,955.9 mi) from Earth ...

WebClairaut's theorem characterizes the surface gravity on a viscous rotating ellipsoid in hydrostatic equilibrium under the action of its gravitational field and centrifugal force. It was published in 1743 by Alexis Claude Clairaut in a treatise which synthesized physical and geodetic evidence that the Earth is an oblate rotational ellipsoid. It was initially used to …

WebNewton predicted that it must be flattened at the poles and bulging at the equator, in other words, an oblate spheroid. The force, F, needed to keep an object in circular motion is given by F = mω 2 r where m is its mass, ω its angular velocity, and r its orbit radius. The angular velocity is the same everywhere on the Earth’s surface.
