The Earth travels on its orbit at a speed of approximately 4400 km per hour. Why do we not feel this high speed ?
We are too small compared to the size of the Earth
Our relative speed with respect to the Earth along the Earth's orbit is zero
The gravity of the Earth constantly pulls us towards the Earth's centre
The solar system as a whole is also moving
Answer is Right!
Answer is Wrong!

– In physics, we typically feel acceleration (changes in speed or direction), not constant velocity. Since our velocity relative to the Earth’s surface (for the orbital motion) is zero and remains zero, we don’t feel the orbital speed.
– This is related to the concept of inertial frames of reference. We are in the same inertial frame as the Earth’s surface for this motion.
