let’s assume a waterbody on the surface

of the Earth.

Your Topic Goes Here

• Your subtopics go here How weak the lunar gravitational force is.

Such a weak force, and we can count on it to oscillate currents and flood tides?

It is so obvious that the lunar gravitational

force doesn’t make much sense to the cause of tides on the Earth.

6

Using the same way, we can get that the solar gravitational force on a waterbody on the Earth is only 1/1745 the Earth’s gravitational force on the same waterbody.

This means the solar gravitational force is weak too, though it is much bigger than the lunar. (All numbers here are from reference books, and are used as approximate numbers. )

So now we can conclude: If the gravitational forces are the forces that

cause tides on the Earth, the Sun should be the significant influence not the Moon.

But this isn’t in accord with the characteristics

of the tidal changes.
