| Abstract: | In this article, how the tide of the ocean water produced by the attraction of the moon decelerates the rotation of the earth is explained, emphasized on the action of the frictional force between the ocean water and the ocean bottom. The effect on the motion of the moon by the "reaction" of the water tide is also explained briefly. |
