Why Don’t We Feel The Earth’s Rotation? Explained

In 1514 A.D Nicolaus Copernicus a polish astronomer postulated the theory, states that the Earth spins on its axis and revolves around the Sun. Since then it is a scientifically proved and well-known fact. later scientists were able to calculate that the Earth spins at a speed of about 1,000 miles per hour and orbits around the Sun at a speed of 67,000 miles per hour.

But have you ever wondered If Earth is revolving with such an enormous speed why can’t we feel that speed?

The answer lies in the nature of motion itself. We don’t feel constant motion. We only feel the motion when there is a change in speed or change in direction.

For Instance,

Think of yourself being on an airplane where it smoothly traveling at a constant speed and constant altitude, yet you can unbuckle your seat, go for a walk still you do not feel the motion of the plane. The simple reason behind this is that you, the plane, and everything inside the plane is traveling at the same speed. In order to pursue motion, you have to look through the window or overcome a sudden change in speed to feel the motion.

Just like we cannot feel the motion of the plane,  in the same manner, the gigantic space ride of Earth is also unperceived. The reason is that spinning and orbital speeds of the Earth stay the same and constant with us, as a result, we do not feel any acceleration. Simply put, If Earth rotates then we and all the other things on Earth are rotating with it at and at the same speed. This is the reason why we don’t feel any acceleration.

If there is any change in the orbital speed of the earth then we would certainly feel that motion.

So why does Earth spins so constantly without any interruptions?

Simply because there is no hindrance to the Earth from doing so. To grasp this understanding, we need to first understand Newton’s 1st law of motion. According to this law- an object in motion will remain in motion until or unless acted upon by an external or unbalanced force. Simply put, the Earth will remain in the same motion or acceleration unless some force exerts on it.

Until then let’s enjoy the incredible journey of our Earth.
