Question

We know that rotation and revolution are two chief motions of the earth.
Why do we not feel these motions?​

Answer 1

Answer:

Explanation:

What evidence do we have that the Earth rotates? An invention called a Foucault pendulum provides evidence that the Earth is rotating on its axis. The swinging pendulum would always trace a straight line as it swings back and forth if it were sitting on an unmoving surface.

Answer 2

Answer:

Bottom line: We don't feel Earth rotating on its axis because Earth spins steadily – and moves at a constant rate in orbit around the sun – carrying you as a passenger right along with it.According to the gravitational force every thing is attached to the earth, keeping everything at rest at their original position, unless any external force compels to motivate it.
