Rotating Events in Our Time

A lot of people know that the Earth revolves around the sun each day for 24 hours, but not all realize that our planet’s rotational speed fluctuates slightly. It’s possible that a day could appear longer or shorter than what you’d expect. This is why the clocks made of atomic energy that keep a standard time must be regularly adjusted, adding or subtracting a second. This is referred to as a leap second. This article will describe what is a leap second and why it’s crucial to our daily routines.

A typical rotating event is precession, which is the oscillation of Earth’s axis of rotation, much as a spinny, slightly off-center toy top. This change in axial orientation relative to fixed stars (inertial spaces) has a duration of 25,771.5. This is also responsible for the direction of cyclones in the Northern Hemisphere as well as in the Southern Hemisphere. Other rotating events include the Chandler wobble free nutation, the polar motion.

In addition to these periodic events, the speed of the rotator can be affected by weather conditions and other elements, including earthquakes. For instance, if the core of the Earth rotates faster than its outer layer, days will appear to be shorter. This is due tidal force acting on the Earth’s surface as well as gravity pulls of other massive objects within the Solar System such as Jupiter and Saturn. This is why it’s important to consider the Earth’s speed of rotation when creating fun park rides such as Ferris wheels and Carousels.
