Astronomy question

If the world is always spinning, why dont we feel as though it is spinning?

Also if we stand at Antarctica, at the South Pole,why dont we fel as though we are upside down?

Re : Astronomy question

We don't feel the spinning of the earth because we are spinning too.

If we were standing on something that was spinning relative to us then we would feel it - but because we are moving at the same rate as the earth we don't notice the movement, in the same way that when you are in aeroplane you don't feel the movement.

It is movement RELATIVE to another object or frame of reference that we notice and experience through the push and pull forces applied on us when experiencing such travel.
