How to study the effect of the Sun or the Moon?s gravity on ocean motion? Of course, Newton?s gravity should be considered. However, Newton?s law considers the Earth as a 0-D point, the ocean motion inside of a 0-D point of the Earth is negative 3-D, and Newton?s law becomes invalid in a negative space. In order to solve the problem, we divide the Earth into two parts, one part is the studied ocean, the other is the left Earth without the ocean. A mechanics model can be then established for the 0-D ocean dynamics.
