Many people are aware of the fact that the Earth revolves around the sun every 24 hours, but they don’t realize that our planet’s orbital speed varies slightly. A day can sometimes seem longer or shorter than what you’d expect. That is why the Atomic clocks that regulate standard time have to be periodically adjusted by adding or subtracting a second. This is referred to as leap seconds. This article will describe how this change occurs and why it is important to you could try this out our daily schedules.

One standard rotating event is precession, a periodic wobble of Earth’s central axis of motion, similar to like a slightly off-center rotating toy top. This axial shift relative to fixed stars (inertial space) has a cycle of 25,771.5 years. It’s also responsible in changing the direction of cyclones within the Northern and Southern Hemisphere. Other rotating events include the Chandler wobble as well as free nutation and Polar motion.

The rotator’s speed can be affected by other factors such as weather conditions, earthquakes, and other recurring events. If the core of Earth rotates faster, then the day will feel shorter. This is due to tidal forces that acts on the Earth’s surfaces, as well gravitational pulls from other large objects within the Solar System such as Jupiter and Saturn. This is the reason that the Earth’s rotational speed must be considered when creating fun park rides such as Ferris wheels and carousels.
