Reference literature confirms that tides are caused by the moon's gravitational pull, and specialized sources explicitly note that this pull creates a bulge on the far side of Earth.
It is a major misconception that freely falling reference frames are inertial in a gravitational field. This is one outcome when employing Einstein’s principle of equivalence between a dynamical acceleration and a homogeneous gravity, which does not exist technically in nature, because gravity is radial from all mass centers, even at nearly infinite distances between masses. Even though floating objects within a space station orbiting Earth appear to move with constant inertial velocities, tidal forces exist to accelerate all such objects. The four oceanic tides of Earth prove that the Moon and Sun are the two external gravitational bodies pulling on Earth, even if an earthbound observer cannot physically feel the tidal forces. Theoretical experiments demonstrate how to observe tidal effects internally to determine the external gravitational forces. Tidal forces make dumbbell-shaped artificial satellites rotate around a heavenly body once per orbit. A liquid in free fall like mercury becomes prolate in shape and aligns with the external gravitational force if the liquid’s surface tension can be minimized. Today’s technology is very precise and can detect most subtle forces, so that local experiments can distinguish between a reference frame in free fall versus a truly inertial frame placed far away from gravitational bodies. Tidal forces always exist in any neighborhood of a test mass due to the radial gravitational force from any external mass, so the mathematical limit of a shrinking local reference frame always contains tidal forces within its domain. Thus, Einstein’s equivalence principle is an approximation and is technically applicable for only point masses.
Tide is a phenomenon that occurs due to the gravitational pull of the moon on the surface of the oceans and seas. This force causes the daily movement and displacement of the water surface. Since the waters of the oceans are more flexible due to their fluid and soft nature compared to the land, this effect is more observed in them. The moon's gravitational force pulls the water towards itself and creates a bulge on its surface, called the tide. Conversely, in the area where the moon's gravitational force has less effect on the seas, the waters recede, and this phenomenon is called the ebb. The main issue is that the moon's gravity is one-sixth of the Earth's gravity; how can the moon have a greater effect on the waters and create tides, and why does this phenomenon occur is considered an important research question. This research aims to examine how tides occur and the factors effecting them. The research method is descriptive, using library studies and scientific articles. The research findings indicate that the moon's gravity is the main reason for tides, and the sun also plays a role in creating tides. However, due to its great distance from the Earth, its effect is less than the moon.

The size and strength of a wave depend on how fast and long the wind blows, and how much open water (called the fetch) it travels across. Waves crash onto beaches, shape coastlines, and can even carry energy across entire oceans.[55] Tides are another important ocean movement. They are the regular rise and fall of sea levels, mostly caused by the gravitational pull of the Moon and the Sun. When the Moon and Sun line up, we get spring tides, which are especially high and low. When they are at right angles, we get neap tides, which are more moderate. Tides affect sea life and the way people use coastlines.[56][57] There are also internal waves, which happen under the surface of the ocean where different layers of water meet. These waves cannot be seen from above, but they are very important because they help mix ocean layers and move nutrients around.[58] Another key process is upwelling. This happens when deep, cold water rises up to the surface, bringing nutrients with it. These areas, like those near Peru and California, are some of the most productive places in the ocean.
Life is dense with phenomena that repeat in regular intervals. Each day, for example, the tides rise and fall in response to the gravitational pull of the moon. Similarly, the progression from day to night occurs as a result of Earth’s rotation, and the pattern of the seasons repeats in response to Earth’s revolution around the sun. Outside of nature, many stocks that mirror a company’s profits are influenced by changes in the economic business cycle.
In mathematics, a function that repeats its values in regular intervals is known as a periodic function. The graphs of such functions show a general shape reflective of a pattern that keeps repeating. This means the graph of the function has the same output at exactly the same place in every cycle. And this translates to all the cycles of the function having exactly the same length. So, if we know all the details of one full cycle of a true periodic function, then we know the state of the function’s outputs at all times, future and past. In this chapter, we will investigate various examples of periodic functions.
