WebAug 7, 2024 · The rotation of the Earth about its axis makes it bulge at the equator and contract at the poles due to the centrifugal forces. How do we know, without any external references, that the Earth is spinning if there is nothing to compare it to? For example, imagine it was spinning in empty space with no other objects. The planet Earth has a rather slight equatorial bulge; its equatorial diameter is about 43 km (27 mi) greater than its polar diameter, with a difference of about 1⁄298 of the equatorial diameter. If Earth were scaled down to a globe with an equatorial diameter of 1 metre (3.3 ft), that difference would be only 3 mm … See more An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body's axis. A rotating body tends to form an oblate spheroid rather … See more The fact that the Earth's gravitational field slightly deviates from being spherically symmetrical also affects the orbits of satellites through secular orbital precessions. They … See more • Astronomical object § Shape • Clairaut's theorem (gravity) • Earth's gravity • Planetary flattening See more Gravity tends to contract a celestial body into a sphere, the shape for which all the mass is as close to the center of gravity as possible. Rotation causes a distortion from this spherical shape; a common measure of the distortion is the flattening (sometimes called ellipticity or … See more Because of a planet's rotation around its own axis, the gravitational acceleration is less at the equator than at the poles. In the 17th century, following the invention of the pendulum clock, … See more

WebThe moon pulls on the Earth and slows down the Earth’s rotation. The moon’s pull creates a bulge near the Earth’s equator, which means there is a lower level of water at the poles.

It is zero if there is no change in the distance from the object of interest to the axis of rotation. Coriolis force is perpendicular to the velocity (in the rotating frame), not to the centrifugal force. lithography suppliers
