Rotation and Orbits - Rotation's moving effects
Rotation's moving effects
Earth's daily tides are caused both by gravity and our planet's spinning movements. Both the Sun and Moon produce a gravitational pull on
Earth. Yet because the Moon is closer to Earth than the Sun, it has about double the gravitational force as that of the Sun, which means it has about double the influence on the tides.
As the Moon revolves around Earth, the Earth and Moon are revolving together, like one unit, around a common point located within the Earth. This point is called the center of gravity or the center of mass. At this center of gravity, the gravitational forces of the Earth and the Moon pull out on each other equally. As the two objects rotate as one system, everything in and on Earth experiences centrifugal forceThe apparent force pushing a rotating body away from the center of rotation.. (While centrifugal...
