Why dont we feel earths rotation?

  1. Mar 29, 2013 #1
    Earth is completing one rotation in one day i.e, in 24 hours. Its equator length is around 40,000 km. Every point on equator is moving with a speed of 40,000/24 i.e, 1667 km/hr. Why dont we feel that speed even though we are moving at such high speeds when we are at equator?

    We don't get blown over because the air moves with the earth. We weigh a tiny bit less at the equator because of the spin. Gravity continues to act vertically downwards, so we notice no changes in the forces on us because there are no changes in magnitude or direction.

    Magic effects of inertia :)
