Isaac Newton Research Paper

Before the discoveries of the great Sir Isaac Newton, there were other theories revolving around gravitational theory. The theory began around 340 B.C. from the mind of Aristotle, though Aristotle's theory of gravity was quite different. He believed that objects would try and return to their “natural place”, which was partly true at the time saying that the “natural place” was Earth itself. After Aristotle came Galileo, who changed the theory of gravitational movement. In Galileo's theory he stated that all objects would accelerate at the same speed in a downward motion disregarding the mass of the object, which gave the first actual understanding of gravity. Then came Johannes Kepler, a german physicist who developed the first three laws of

Isaac Newton was a seventeenth century physicist, astronomer and mathematician, who is also acclaimed to be one of the greatest minds in history. Not only being the man to give us the modern day gravitation theory, but also the three laws of motion. Newton’s law of universal gravitation states that every mass attracts every other mass in the universe, and the gravitational force between the two objects is even to the product of their masses, divided by squared distance between them.

Henry Cavendish was the next great gravitational theory physicist. He contributed to the overall theory by giving a value to Newtons symbol for the gravitational constant (G). His value was 6.67*10^-11, which he concluded from his experiment. Cavendish's experiments for determining the value of G involved a rod about 2-feet long. Two small spheres were attached to while the rod was suspended by a thin wire. When the rod twisted, the torsion of the wire begins to exert a force that is proportional to the rotation of the

A marble moving along a cloth will be drawn towards the ball, as the Earth is to the Sun, but it will not fall into it as long as it keeps moving at constant speed. Einstein argue that gravity was not an attractive force between bodies as had been previously thought. Although there are celestial bodies that can warp space-time.Black holes are areas of space with such a high gravitational pull that not even light can escape the chasm. Black holes are real celestial objects, and are formed by dying planets imploding on themselves. The Schwarzschild Radius, is the radius of a event horizon of a nonrotating black
