The first thing you should know is that our planet has several types of movements, which are, according to science, what the star does in relation to the Sun. The best known are the displacement of translation and rotationbeing the first the one that makes the Earth around the Sun and the second when it rotates on its own axis.

Taking into account the above, the planet takes 365 days to complete a movement of translation at a speed of 107 thousand kilometers per hour, according to the measures imposed by space agencies.
We move at the same speed as the Earth.
On the other hand, the rotation time is 24 hours, a figure that has been under discussion in recent months, because the The International Service for Earth Rotation and Reference Systems (IERS) stated that the planet broke records by completing the shortest day in history for as long as records have been kept.
According to the entity, the star rotated 1.59 milliseconds faster than usual, so it has been said that it supposedly began to move faster. Which leads to the question: why do we not feel the increase in the speed of our home?

Do we perceive accelerations?
According to some specialized media, the human being is unable to perceive the movement of the Earth, because it is at a constant speed. Despite everything, it is capable of perceiving accelerations and movements at rest.
Imagine that you are traveling in an airplane, you will undoubtedly feel how it takes off and lands, but not its movement in the air, because you are in a constant state of acceleration and you are moving at the same speed as the aircraft.
This being the case, if the star slows down in a resounding way or, on the contrary, increases its speed, we would feel the change of environment. In other words, both you and everything that is immersed in the planet rotates at the same speed and therefore does not feel the movement.

The ear
Likewise, we are not able to capture the planetary movement because it is carried out very slowly: only 15 degrees of rotation every hour, or what is equal to 0.004 degrees per second, well below the internal perceptual threshold of our ear as to capture disturbances in the terrain.
Just so you understand, if you could spin around in an office chair at that speed you wouldn’t feel a thing either. In other words, a person would take a full revolution in half an hour at the speed of Earth’s rotation.
