Rotating Events in Our Time

Most people are aware that the Earth rotates around the Sun each 24 hours. However most people don’t know that the speed of rotation differs slightly. This means a day can sometimes feel longer or shorter than expected. The nuclear clocks, that maintain the standard time, have to be adjusted every few days by adding or subtracting one second. This change is known as a leap second. This article will explain what a leap second is and why it’s crucial to our daily schedules.

Precession is a common rotating event. It is the cyclical wobble of the Earth’s axis, similar in nature to a toy top that spins slightly off-center. This axial shift relative to fixed stars (inertial space) has a time lapse of 25,771.5 years. This is also responsible for the direction of cyclones both in the Northern Hemisphere and in the Southern Hemisphere. Other rotating events include free nutation as well as the Chandler wobble, and the polar movement.

The rotator’s speed can be affected by other factors such as weather conditions, earthquakes, and other events that occur regularly. If the core of Earth rotates faster, a day can feel shorter. This is due tidal force that is 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 the reason the Earth’s rotating speed has to be accounted for when designing fun park rides, like Ferris wheel and carousels.
