The Moon does not pull water “like a magnet.” It pulls everything on Earth through gravity, but because water is fluid and can move more freely, the effect is much more visible in the oceans.
How does it work?
F = G\frac{m_1 m_2}{r^2}
This means:
* The greater the mass, the stronger the gravitational force
* The smaller the distance, the stronger the pull
Why do tides happen?
1. The side facing the Moon:
The part of Earth closest to the Moon feels a slightly stronger gravitational pull, so ocean water bulges toward the Moon.
2. The opposite side also has a tide:
Earth and the Moon rotate around a shared center of mass, creating an inertial effect on the far side, which causes water there to bulge outward too.
Result:
Because of these two bulges, most places on Earth experience:
* 2 high tides
* 2 low tides
each day.
Why is the effect more obvious in water?
* Water can flow and change shape easily
* Land is also pulled slightly, but because it is solid, the movement is much less noticeable
example:
Imagine a large ball filled with water—if you gently pull one side, the water shifts and bulges in that direction. The Moon does something similar to Earth’s oceans, but on a massive scale.
