Most people are aware that the Earth revolves around the sun each day for 24 hours, but few realize that our planet’s orbital speed fluctuates. This means that a day may sometimes seem longer or shorter than expected. The clocks that are atomic, which maintain standard time, have to be adjusted every few days by subtracting or adding one second. This change is called a leap second. This article will describe how this change occurs and why it matters to our daily schedules.

One of the most common rotating events is precession, which is the cyclical wobble of Earth’s axis of motion, similar to like a slightly off-center spinning toy top. This axial shift relative to fixed stars (inertial space) is observed for a period of 25,771.5 years. This is also the reason for the direction of cyclones in the Northern Hemisphere and in the Southern Hemisphere. Other rotating events include free nutation and the Chandler wobble and polar motion.

In addition, to these periodic events, the speed of a rotator can also be affected by weather conditions and other factors like earthquakes. For example, if the core of the Earth is rotating faster than its outer layer, the day will appear to be shorter. This change is caused by tidal forces acting on the surface of the Earth, as well as gravity pulls from other 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 designing fun park rides such as Ferris wheels and Carousels.
