Sir Isaac Newton's Law Of Universal Gravitation Essay

The general and widespread acceptance of Sir Isaac Newton’s models and laws may often be taken for granted, but this has not always been so. Throughout history, scientists and philosophers have built on each other’s theories to create improved and often revolutionary models. Although Newton was neither the first nor the last to bring major innovations to society, he was one of the most notable ones; many of his contributions are still in use today. With the formulation of his laws of motion, Sir Isaac Newton contributed to the downfall of Aristotelianism and provided a universal quantitative system for approximating and explaining a wide range of phenomena of space and the physics of motion, revolutionizing the study and understanding

Newton’s first law of motion states that an object in motion will remain in motion, while an object at rest will remain at rest unless acted upon by another force. This seems to be true with humans as well because it is more likely that a person will remain active in their later years if they remain to be active through the critical time of their late teens and twenties. Because a major portion of this age category is in college, it is crucial for universities and community colleges to provide physical education to help students achieve and maintain a standard level of physical and mental fitness outside and inside the classroom.

Sir Isaac Newton, an astronomer, mathematician, and a scientist is described to be "one of the greatest names in history of human thought.”  According to biography.com, Newton was born on December 25, 1642 in Woolsthorpe, Lincolnshire, England, and was interested in creating mechanic toys as a young boy (2016). He even invented an impressive, small windmill, which would grind wheat and corn, at a young age. Newton explored beyond the secrets of light and color, found gravity, and even discovered a new form of mathematics, called calculus. It was Newton who had explained why a rock is heavier than a pebble, and how earth's gravity could hold the moon in its orbit. Isaac Newton’s discoveries proved him

Isaac Newton is considered one of the most important philosophies (scientist) in history. One of the biggest accomplishments the newton created was discovering the theory of gravity. Defined in the Principia, his theory about gravity helped to explain the movements of the planets and the Sun. This theory is known today as Newton's law of universal gravitation. Also Newton's created the laws of motion were three fundamental laws of physics that laid the foundation for classical

The Law of areas, which means that all planets sweep out equal areas in equal time.

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.

Nicholas Copernicus was the first to question the universal truths and teachings of the church. He devised a theory that the earth along with the other planets revolved around the sun. This theory disagreed with Aristotle and the old teachings that the universe revolved around the earth, and that man was the center of the universe.

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

Another contributor to the Scientific Revolution was Galileo Galilei. A professor at the University of Padua, Galileo, like Copernicus, began to doubt the theories of philosophers and scientists, such as Aristotle, and using his self-built telescope, Galileo studied the skies and came to support the Copernican theory. Galileo considered himself a devout member of the church, but he disagreed with the Bible's teachings in many cases. He once stated that, "The Bible shows the way to go to Heaven, not the way the heavens go."4 Through his telescope, Galileo noted that there was no distinction between the Heavens and the Earth, a belief that was contrary to former scientific and church teachings. Also, Sir Issac Newton, took the work of his predecessors a step further and developed the Law of Gravitation. He theorized that the planets moved in the manner that they did because of the forces of gravity. This was yet another blow to the former

One of the most well known is, “To every action there is always an opposed and equal reaction”.2 These three basic theories are the most widely known theories that Newton proposed. The development of these theories founded what is now modern physics. These theories also gained Newton attention and credibility in the scientific community, which further helped spread his accomplishments.

His first law states, “The orbits of the planets are ellipses, with the Sun at one focus of the ellipse.” As shown in Figure 1, The Sun is not at the focus of the ellipse, but is instead at one focus [usually there is nothing at the other focus of the ellipse]. The planet then trails the ellipse in its orbit, which implies that the Earth-Sun distance is continually changing as the planet goes around its orbit. Kepler’s second law states, “The line joining the planet to the Sun sweeps out equal areas in equal times as the planet travels around the ellipse.” As shown in Figure 2, an imaginary line from the center of the sun to the center of a planet sweeps out the same area in a given time. This means that planets move faster when they are closer to the sun. Kepler’s third and final law states, “The time taken by a planet to make one complete trip around the sun is its period. The ratio of the squares of periodic times for two planets is equal to the ratio of the cubes of their mean distances from the sun.” Kepler’s third law indicates that the time taken by a planet to orbit the Sun increases quickly with the radius of its orbit ("Johannes Kepler: The” 1-4). Kepler’s laws challenged Aristotelean and Ptolemaic astronomy. His statement that the Earth

After Tycho’s death, his assistant, young mathematician Johannes Kepler used Tycho’s observations and came up with his First Law that orbits of the planets are elliptical instead of round like Copernicus believed. With his Second Law, Kepler stated that the speed of the planets depends on their distance from the sun which helped English astronomer and physicist Isaac Newton, to come up with his Law of Universal Gravitation.

Isaac Newton was born in a time were a lot of ideas and concepts were being discovered but he discovered one of the

In this quote Newton is saying that known of his work would have been possible if it had not have been for the philosophers and scientists before him. The “giants” are people like Galileo and Aristotle, Newton was “standing on the shoulders” of them, he used their knowledge and findings to help create his.

Nonetheless, nothing could take away from Newton’s innate ability to understand the world around him in ways that nobody had been able to before.
