Standing here on the earth

    [SOLVED] standing here on the earth

    1. The problem statement, all variables and given/known data
    When I am standing here on the earth, the effective net force on me in the rotating reference frame of the earth must be 0. However, consider the forces on me in an inertial frame with origin at the center of the earth. Then the net force on me would be gravity minus normal, correct? And that should equal Rw^2 where R is the radius of the earth and w is the angular velocity of the earth's rotation. Assume I am at the equator. Is all that correct?

    2. Relevant equations
