Why cant we feel the earth spinning?
gpt
When you spin around on a tire swing, you feel a force pushing you outward.  This is called centrifugal force, and it results from the fact that your body wants to move in a straight line, rather than in the circular path of the tire swing.

On the surface of the earth, the force of gravity we experience is much greater than the centrifugal force.  So you can't really "feel the earth spinning" because it gets drowned out by gravity.
