This is an essay I did on explaining how gravity works as well as how it effects the tides... How high tide and low tide work

String Theory is the theory of a theoretical framework in which the point-like particles of particle physics are replaced by one dimensional object called strings. The theory describes how the strings proliferate through space and cooperate with each other. On distances larger than the string scale, a string looks like an ordinary particle, with charge, mass and other properties determined by the vibrational state of the string. One of these vibrational states that the strings corresponds to the graviton, the quantum mechanical particle that carries gravitational force and therefore if string theory were to be correct, it would also prove the existence of the graviton. However String theory cannot be proved because the string unit is not yet measurable and even if the string unit could be measured, other elements of string theory (such as its proposed 11 dimensional cosmology) would also need to be verified empirically.

Gravity: Gravity is a force of nature that keeps things on Earth instead of floating out of the atmosphere.

no one is really sure what causes gravity, but the effects have been studied by many

A given spot on the coast will experience two high and two low tides each day. High tide occurs when the Moon and Earth are facing towards each other and away from each other. Low tide occurs when the Moon is facing the Earth at 90˚ and 270˚.

All the behavior relating to particles and forces is described by the Standard Model but except gravity. It seems hard to prove and describe this force in microscopic forms. Over the years, it seems hard to formulate the quantum theory of gravity. In the attempt to describe the microscopic theory of gravity, the string theory emerged. The they attempt to complete, unify and give a consistent description of the fundamental structure of the universe. This

1. Identification: In the 17th century, various fields of science began to advance. Isaac Newton combined the ideas of earlier scientists, and developed the concept of gravity.

Therefore, during experiment (2:39 pm first in and 4:01 pm last out), we had second low tide after we put meter stick on 2B but before 3A. Then, the graph shows that the tide started to rise slowly during rest of period. 1B (2:40 - 4:01 pm), 3A (3:01-3:52 pm) and 4B(3:13-3:38 pm) have positive

waves to larger waves. When the water starts to move it is subject to the Coriolis

In 1916 Einstein proposed his new General Theory of Relativity that built upon Newton's Universal Theory of Gravitation which showed "that gravity is responsible for the motions of both planets and falling objects near the Earth" (Fix, p 86). Einstein' theory "describes gravity as a curvature in four-dimensional spacetime" (Singh, p. 502). The original intent of the theory was to explain the inaccuracies of Mercury's orbit when using Newton's law and the Sun's bending of light.

First explained with science by Isaac Newton in 1686, tides are known as the regular rise and fall of the ocean. Tides are created by the gravitational forces of the sun and the moon. A high tide is created when the moon's gravitational force tugs on water from the oceans and causes bulges. Even though high tides would be the most powerful on the side of Earth facing the moon, high tides will occur throughout the whole earth. Sometimes, depending on the Earth’s stage during the orbit around the sun, the earth is able to have special and even sometimes rare tides. One tide that’s rare is known as The Proxigean Spring Tide. The rare Proxigean Spring Tide is a very high tide that produce large waves. It occurs when the moon is unusually close to the Earth and in a new moon phase. When this type of tide occurs, it also means that the moon is between the earth and sun. In the book Life as We Knew It when the moon his with an asteroid knocking it out orbit. The moon gets very close to earth and the first natural disaster to occur are tidal waves. The Proxigean Spring Tide came to mind because the moon, in order to happen,the moon must be unusually close

Explain why the Sun's influence on Earth's tides is only 46% that of the Moon's, even though the Sun is so much more massive than the Moon.

First, Sir Isaac Newton discovered gravity after observing an apple fall to the ground. However, one of his most notable contributions is not the discovery of gravity but his discovery that gravitation is universal. The force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers.

Before Newton talked about gravitation the main knowledge of scientists was a elementary knowledge of optics, mechanics and astronomy.Copernicus Kepler and Galileo provided the background knowledge of the stars and planets, but Newton used their data to discover the whole gravitational system.10Newton reasoned that the planets and all other physical objects in the universe moved through mutual attraction of gravity.Newton said that every other object in the universe affected every other object through gravity.This explained why the planets move in an orderly fashion. Newton found that “the force of gravity towards the whole planet did arise from and was compounded of the forces of gravity towards all it’s parts, and towards every one part was in the inverse proportion of the squares of the distances from this part.”Newton proves all of this mathematically. This was known to be the single most important contribution to physics that ever has been made.11

6. What causes ocean tides? Tides are caused by the gravitational pull of both the moon and the sun. The moon being closer has a greater effect on tides. Water on the side of Earth closest to the moon bulges toward the moon. There is also a bulge away from the moon on the opposite side of the Earth.

General Relativity is a two part theory created by the German physicist, Albert Einstein. The two sections of relativity is special relativity and general relativity. Special relativity focuses more on lines, constant-velocity motion on the mass of objects, the passage throughout time, and that passing the speed of light is impossible. General relativity deals with accelerated motion, gravitational fields on mass, size, and time. General relativity also states that matter and space effect each other and that the universe ends and there may be more universes out there. Relativity also includes space-time. Many people think that space and time are completely different variables, but physicists often combine them into “space-time”. Space-time is a four-dimensional coordinate system used in relativity and other areas of physics. The dimensions are, length, width, height, and the 4th is the time dimension.
