Why does the same side of the moon always face the ground?
The same side of the moon always faces the ground. The "dark side" is not actually dark - it gets cycles of the day and night as much as most places on Earth - the "distant side" is a more correct term. The reason one party is never visible from the country is that it spins once on its axis at exactly the same time than it revolves around the ground. If its rotation rate was slightly different from its speed of revolution, they would eventually be exposed to the entire surface of the moon. However, these two intervals were the same for the whole recorded history and were probably for millions of years or more. Through their gravitational attraction, the Earth and the Moon create a tidal bulge on top of each other, with one bulge heading in the direction of the other body and one pointing. These bubles generate heat by friction of the rock that wipes against each other, and also turns into greater orbital power for the Moon, which means that it is constantly coming from the ground. Over time they sip the energy from the rotational momentum of both bodies and createThey solve the brake effect.
Because the Earth's mass dominates the ground-month system, the moon is experiencing a greater brake effect. Over time, its rotation gradually slowed until the speed of rotation coincides the speed at which the tidal bulge moves around the body. Today, the lunar tidal bulges are placed in a constant position due to the rotation of the moon, which means that a kind of balance has been achieved.
Themeasure of Earth's rotation also slows over time due to tidal forces, but the brake effect is much smaller - to be perfectly synchronized with the moon, the ground would have to rotate only once in a lunar cycle, or about 29.5 days. Then the moon would always be in the same place in the sky and visible only from one side of the Earth, but it is not. In some planetary systems, such as the dwarf planets Pluto and its satellite Charon, both bodies are tidal to each other.
