Rotational Speed facts
While investigating facts about Rotational Speed Of Earth and Rotational Speed Formula, I found out little known, but curios details like:
The NFL uses tracking chips embedded in players shoulder pads to record a players every move on the field. They are also located inside footballs to track: velocity, rotation ,ball speed and location.
how rotational speed is changed to linear speed?
The Japanese earthquake in 2011 increased the Earth's rotation speed, shortening the day by 1.8 microseconds.
What rotational speed would be required to simulate gravity?
In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what rotational speed is needed. Here are 40 of the best facts about Rotational Speed Calculator and Rotational Speed To Linear Speed I managed to collect.
why is rotational speed maximum at the equator?

An armored vehicle prototype invented by Preston Tucker in 1930s. Tucker Tiger, as it was called, was entirely bulletproof, had air conditioning, and a turret that could rotate 360 degrees. Its maximum speed was 114 mph, but it was rejected by the Army because they felt it was too fast.

Arthur Ganson's "Machine with Concrete", a kinetic sculpture of 12 connected gear pairs with the last gear stuck in concrete. It can still turn though, due to gear reduction that cuts the rotational speed by 1/50th for each gear set. The last gear will take over 2 trillion years to turn once.

If Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator. All of the land masses would be scoured clean of anything not attached to bedrock.
-
The theory that in 'Superman' (1978), Superman doesn't actually turn back time by litterally reversing the earth's rotation. Instead, he himself travels to the past by flying faster than the speed of light, and the reversing earth is simply a visual metaphor for this.

The 2011 earthquake in Japan was so powerful it moved Honshu (the main island of Japan) 2.4m (8 ft) to the east, shifted the Earth on its axis by estimates of between 10 cm and 25 cm, and increased earth's rotational speed by 1.8 µs per day.
-
The neutron star 'PSR J1748-2446ad' rotates on its axis 716 times per second, and is the fastest spinning known neutron star. At its equator, it spins at 24 percent of the speed of light.
-
Neutron star PSR J1748-2446 is the fastest spinning celestial object in the universe. The star rotates 716 times every second, so its equator moves at about 25% the speed of light. It is also 50 trillion times the density of lead and has a magnetic field a trillion times stronger than the Sun’s.
-
The Voyager 2 carried a tape recorder whose reels rotated at high speeds which caused issues with its operations. Due to the conservation of angular momentum, the space probe started an undesirable rotation in the opposite direction whenever the tape recorder was turned on.
-
Due to irregularities in Earth's rotation speed, clocks sometimes strike 23:59:60 to stay in sync with a day's real duration, essentially creating minutes with 61 seconds.
-
The 2011 earthquake near Japan increased the Earth's rotation speed, shortening the day by 1.8 microseconds.
Why does volumetric efficiency decrease with rotational speed?
You can easily fact check why is the rotational speed of the earth by examining the linked well-known sources.
In 2011 earthquake near Japan increased the Earth's rotation speed, shortening the day by 1.8 microseconds.
He made these determinations by improving on the design of the rotating mirror that had originally been used to measure speed of light.
Uranus is the seventh planet from the Sun, it has the third largest planetary radius and the fourth largest planetary mass in the Solar System. Uranus is unique because its axis of rotation is always tilted sideways, which means that its north and south poles are where other planets have their equators. Wind speeds can reach up to 560 miles per hour (900 kilometers per hour).
In 1862 Foucault used a rotating mirror in an enclosed space to accurately determine the speed of light and he became interested in precision engineering.
The speed of light was calculated in 1849 using mirrors and a rotating cog. The value was more precise than the previously accepted value from 1676. - source
What happens when the rotational speed of a generator coil is increased?
Modern cars measure the tire-pressure by sensing individual tire rotation and comparing it to speed and other sensory inputs.
How to calculate rotational speed?
If the Earth stopped spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator, and all of the land masses would be scoured clean of anything not attached to bedrock.
Because of the planet Mercury's orbit and rotational speed, some areas of the planet can experience two sunrises and sunsets per day.
The fastest spinning star discovered is a pulsar named PSR J1748−2446ad and is part of a globular cluster called Terzan 5 in the constellation Sagittarius 18,000 light-years from Earth. It rotates at 24% of the speed of light or 716 times per second at its equator.
The same side of the Moon is always facing the Earth due to 'tidal locking'. The Moon rotates at the exact same speed as it takes to orbit the Earth (28 days).
The tides are slowly slowing down the earth's rotation and speeding up the moon's orbit, therefore moving it away from us.
