WebSep 22, 2004 · The bulge of the Earth's equator Assuming the Earth is exactly spherical, we expect gravity to always point towards the center of Earth. ... If the planes flew east … Web20. Many sources state that the Earth's gravity is stronger at the poles than the equator for two reasons: The centrifugal "force" cancels out the gravitational force minimally, more so at the equator than at the poles. The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.
WebTidal heating (also known as tidal working or tidal flexing) occurs through the tidal friction processes: orbital and rotational energy is dissipated as heat in either (or both) the surface ocean or interior of a planet or satellite. When an object is in an elliptical orbit, the tidal forces acting on it are stronger near periapsis than near apoapsis. . Thus the deformation … WebIn this way the combination of gravity and inertia create two bulges of water. One forms where the Earth and moon are closest, and the other forms where they are furthest apart. Over the rest of the globe gravity and …

Webwhere r is the actual earth radius and R e is the effective earth radius. Commonly, the effective earth radius factor, k, is chosen as 4/3.However, at long ranges and with shallow angles, k can deviate greatly from the 4/3. (With no atmospheric refraction, k = 1. An infinite value for k represents a flat Earth). ). The effearthradius function provides two methods …
