In 1514 AD, a Polish astronomer Nicholas Copernicus proposed this theory, noting that the earth rotates on its axis and revolves around the sun. It has been a well-known and scientifically proven fact ever since. Later, scientists calculated that the Earth spins at about 1,000 miles per hour and rotates the sun at 67,000 miles per hour.
But have you ever wondered if the Earth is spinning at such a huge speed, why can’t we
feel that speed?
The answer lies in the nature of the movement itself. We do not feel a constant movement. We only feel movement when there is a change in speed or direction.
Imagine yourself in a plane that flies smoothly at constant speed and constant altitude, but you can unblock your seat and go out for a walk, but you don’t feel the movement of the aircraft. The simple reason behind this is that you, the plane and everything inside the plane travel at the same speed. To move forward, you have to look through a window or overcome sudden changes in speed to feel the movement.
Just as we cannot feel the movement of an airplane, so does the massive journey of Earth into space. The reason is that the rotation speed and the orbital velocity of the Earth remain the same and consistent with ours, so we do not feel any acceleration. In short, if the Earth is spinning, then we and everything else on Earth is spinning with it at the same speed. That is why we do not feel any acceleration.
If there is any change in the orbital velocity of the Earth, then I would definitely feel the motion.
So why is the Earth still spinning without any interruption?
Simply because doing so does nothing for the planet. To understand this understanding, first we need to understand Newton’s first law of motion. According to this law – a moving body will continue to move until or unless acted upon by an external or unbalanced force. In short, the earth will maintain the same movement or acceleration unless some form of force is applied.
Until then, let’s enjoy an amazing trip on Earth.
