Do you think that the everyday 24 hours is exact the same? You think that your watch is telling you everything but it is not. There are forces altering the velocity of the rotation of the Earth. The effect is so small that it is hard to notice. The gravitation forces cause tides by the gravitational forces amid the Earth and from the outer space, the moon, sun etc. causes drag force as they interrelate with this planet. That tidal friction is an additional 2.3 milliseconds to each day. Meteorological conditions structures can alter the Earth’s spin, with airstreams smearing a decelerating force to Earth’s surface. Lastly, earthquakes can muddle with the span of a single day by essentially reallocating the planet’s mass. For example, earthquake that hit Japan during 2011 in fact fast-tracked the Earth’s rotation (since it lifted the mass on the way to the center of the Earth) and reduced the 24 hours by 1.8 microseconds.

This planet is spinning on its axis one time for each 24 hours. In the center of the Earth, the rate of Earth’s spin is aroun1,000 miles per hour (1,600 km/h). Each day consists of 24 hours and we all experience day and night on regular routine but we never notice the spin or the rotation. We do not understand the spin since everything on the planet like humans, atmosphere and Earth’s oceans are circling laterally with the Earth at the identical continual rate.

The land feels secure and hard underneath your feet. Even though the planet is continuously spinning, we are still stable. The secret to our stability and firmness is the gravity. The other reason is momentum. So, you can say for this two things: gravity and momentum you do not feel the earth spin. The external part of the Earth is stirring at 1675 km/h or 465 meters/second. It is 1,040 miles/hour.

**Here is the calculation: **

The circumference at the equator is equal to 40,075 km and the total time to complete one rotation on its axis is 23.93 hours. 40,075 km ÷ 23.93 hours = 1,675 km/hour or 465 meters per second.

Divide the distance by the time. We did not take it as 24 hours because astronomers calculate a day in two ways and it results in the day being 23 hours and 56 minutes. They name it as a sidereal day. The Sun also requires an additional four minutes every day.

Now that you saw the calculation and you know the reasons why the Earth spin changes and how we remain stable. When you are on a plane or car, you think you are stable or you may feel like you are not moving at all. As we mentioned about the watch, you may want to put some additional seconds to it as the Earth’s rotation is decelerating down by two-thousandths of a second each day.
