Many people are aware that Earth revolves around the Sun every 24 hours. However many people are unaware that the speed of rotation is not the same every day. It is possible for a day to appear longer or shorter than what you’d expect. This is the reason timekeeping atomic clocks which maintain standardized time must be periodically adjusted by adding or subtracting a second. This change is known as a leap second. This article will describe what is a leap second and the importance it has to our daily routines.
A typical rotating event is precession, which is the oscillation of Earth’s axis, much like a slightly off-center spinning toy top. This axial shift relative to fixed stars (inertial space) has a cycle of 25,771.5 years. This is also the reason for the direction of cyclones in the Northern Hemisphere as well as the Southern Hemisphere. Other rotating events include the Chandler wobble free nutation, polar motion.
The rotator’s speed can be affected by other variables, including weather conditions, earthquakes, and other recurring events. For instance, if the core of the Earth is rotating faster than its outer layer, a day can appear to be shorter. This is due to the tidal forces that are acting on surface of the Earth, as well as gravitational pulls from other large objects within the Solar System, such as Jupiter and Saturn. This effect is why the Earth’s rotating speed has to be considered when designing fun park rides, like Ferris wheel and carousels.
