The tangential speed of Earth's rotation at a point on Earth can be approximated by multiplying the speed at the equator by the cosine of the latitude. [42] For example, the Kennedy Space Center is located at latitude 28.59° N, which yields a speed of: cos(28.59°) × 1,674.4 km/h = 1,470.2 km/h.

When a Foucault pendulum is suspended at the equator, the plane of oscillation remains fixed relative to Earth. At other latitudes, the plane of oscillation precesses relative to Earth, but more slowly than at the pole; the angular speed, ω (measured in clockwise degrees per sidereal day), is proportional to the sine of the latitude, φ:
Polar motion in arc-seconds as function of time in days (0.1 arcsec ≈ 3 meters). [1] Polar motion of the Earth is the motion of the Earth's rotational axis relative to its crust. [2]: 1 This is measured with respect to a reference frame in which the solid Earth is fixed (a so-called Earth-centered, Earth-fixed or ECEF reference frame). This ...
Earth has reportedly reached its quickest spin speeds in the past half-century.
This minuscule change in time means we might need to consider a negative leap second. Earth Is Spinning Faster Than Usual, Giving Us the Shortest Day EVER Recorded Skip to main content
Replacing =, where is the magnitude of the spin rate of the Earth, to obtain f = ω = 2 Ω sin φ . {\displaystyle f=\omega =2\Omega \sin \varphi .} Thus the Coriolis parameter, f {\displaystyle f} , is the angular velocity or frequency required to maintain a body at a fixed circle of latitude or zonal region.
Earth rotates on its axis at about 1,000 miles per hour. That’s the short answer, but it’s not the whole story.
