Centrifugal force is the unbalanced reaction of inertia to centripetal force. So centripetal force constantly "pulls" us toward the Earth as we orbit, while "centrifugal" force is the inertial tendency of mass (our bodies) to continue moving in a straight line (e.g. flung in to space).

#### NOAA Tides & Currents

The tidal force exerted by the sun is a composite of the sun's gravitational attraction and a centrifugal force component created by the revolution of the earth's center-of-mass around the center-of-mass of the earth-sun system, in an exactly analogous manner to the earth-moon relationship.

#### Why don't we feel the centrifugal force due to the earth's ...

Then, gravity will pull you towards the center of the Earth, but the centrifugal force will effectively throw you outward in the plane of rotation - so you will be thrown "South" a little bit (as "out" is "up + South" relative to the Earth's surface there).
