How quickly does the Earth rotate?

How quickly does the Earth rotate? The answer to this question is not as simple as it seems because speed is always measured relative to some reference frame. For example, we measure the speed of a car relative to stationary objects like the road.

However, the speed of the Earth is measured relative to the center of our planet. The highest speed caused by Earth’s rotational motion is at the equator, while the lowest is at the poles.

How quickly does the Earth rotate? The rotation speed of the Earth at the equator is approximately 1674 km/h (about 465 m/s), while at the poles it is 0 km/h.

One full rotation around its own axis takes the Earth 23 hours and 56 minutes. If the rotational speed of the Earth were to change, we would certainly notice it through changes in the order of day and night.
