As the Moon moves around the Earth: a) The drag force on the Moon keeps it from getting too far away b) The attraction of the Moon to the center of the Earth accelerates it into a nearly circular orbit c) The drag force of the tides on the Moon bends its path into a nearly circular orbit   d) It’s attraction to the Earth is cancelled by the centrifugal force so it moves perpendicular to its orbit
