2. One of the Earth’s
movements - Earth rotating
about the Earth–Moon
barycenter, which I call the
Earth’s “ZiZhuan” (“子转”),
is an eccentric rotation. The
right drawing shows the
Earth doing eccentric
rotation. So, different linear
speeds at different positions.

3. Driven by the Earth’s rotation, a certain Ocean
floor turns to face away from the Moon, with its
speed continuing to increase until it reaches to a
point (Point D) on the Earth furthest from the
Moon. (It is at this point the ocean floor reaches
to its maximum linear speed.) The ocean floor
then passes this point and decelerates. 3

4. At this time period, by
the effect of inertia, the
water above the ocean
floor runs backwards
when the ocean floor
accelerates and runs
forward when the ocean
floor decelerates. In this
way, a flood tide and ebb
tide is achieved.

5. The ocean floor continues to
rotate with the Earth and
turns to face towards the
Moon with its speed
continuing to decrease until
it comes to a point (Point J)
on the Earth nearest to the
Moon. (It is at this point the
ocean floor reaches to its
minimum linear speed.) It
then passes this point and
accelerates.

6. At this time period,
because the overall
speed is slow, the
effect of inertia is not
obvious while another
effect takes the lead –
The “speed inversely
proportional to the area”
effect. And the Moon's
gravitational pull on
the Earth helps too.
