Many people are aware that Earth revolves around the Sun every 24 hours. However most people don’t know that the speed of rotation can vary. It is possible for a day to appear longer or shorter than you think. The clocks that are atomic, which maintain the standard time, have to be adjusted every few days by adding or subtracting one second. This is referred to as leap seconds. This article will explain how this change takes place, and how it matters to our daily schedules.
One standard rotating event is precession, the circular wobble of Earth’s axis of motion, similar to 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. It’s also responsible for changing the directions of cyclones in the Northern and Southern Hemisphere. Other rotating events include the Chandler wobble as well as free nutation and Polar motion.
In addition to these recurring events, the speed of a rotator can be affected by weather conditions and other factors like earthquakes. If the core of Earth rotates faster, a day can feel shorter. This change is caused by the tidal forces that are acting on surface of the Earth and gravitational pulls from other objects in the Solar System, such as Jupiter and Saturn. This is the reason the Earth’s rotational speed needs to be considered when designing fun park rides like Ferris wheel and carousels.
