While the Earth is indeed in constant motion, rotating on its axis and orbiting around the Sun, we typically do not feel this movement on a day-to-day basis due to its gradual and consistent nature.
The Earth completes one full rotation on its axis approximately every 24 hours, causing day and night. However, this rotation is relatively slow and smooth, so we don't perceive the motion directly. Similarly, the Earth orbits the Sun once a year, but the movement is also gradual and doesn't generate a noticeable sensation.
The reason we don't feel the Earth's movement is that we, along with everything on Earth's surface, are also moving at the same speed. Our bodies and surroundings are in a state of constant motion together with the Earth, so we don't experience any relative movement that would make us feel the Earth's rotation or orbit.
It's worth noting that although we don't feel the Earth's movement directly, we can observe its effects, such as the changing position of the Sun and stars in the sky throughout the day and seasons, as well as the annual cycle of the Sun's path.
