Consider the following statements
1. The two most important forces acting on the Earth to create tides are the Moon's gravitational field pulling the ocean towards itself and the centrifugal force, or outward movement from the axis of rotation, caused by the Earth and Moon revolving in their orbit.
2. At the center of both the Earth and the Moon, centrifugal and gravitational forces cancel each other out, preventing the Moon from falling on the Earth and the Earth from flying out of orbit.
3. Both the Earth and the Moon revolve around the one center of both of their masses.
4. This common point is called the barycenter and is located at about ¾ of the radius from the Earth's center.
5. Although the Moon is the Earth's only satellite, the Earth moves slightly when they both orbit the barycenter.
6. In addition, the barycenter is not always in the same place due to the elliptical rotation of the Moon.
7. there is one revolution of the Moon every 27 days, so the angular velocity is the same at all places and the centrifugal force lines up with the radius from the barycenter.
