<ul><li>Sir Isaac Newton was born in 1643 in Woolsthorpe, England.
His father was a wealthy, uneducated farmer who died three months before Newton was born. Newton's mother remarried and he was left in the care of his grandmother.
. He attended Free Grammar school; though Newton did not excel in school, he did earn the opportunity to attend Trinity College Cambridge where he wanted to study law.
Later on in 1665, he discovered the generalized binomial theorem, and began to develop a mathematical theory that would later become infinitesimal calculus. </li></li></ul><li><ul><li>By 1666, he had completed his early work on his three laws of motion and was later published in his book Principia.
As the years progressed, Newton completed his work on universal gravitation, diffraction of light, centrifugal force, centripetal force, inverse-square law, bodies in motion and the variations in tides due to gravity.
However, in 1679 his work came to standstill after he suffered a nervous breakdown. Upon regaining his health Newton returned to the University, and he became a leader against what he saw as an attack on the University by King James II. When William of Orange drove James out of England, Newton was elected to Parliament.
Throughout his career he was torn between fame and his fear of criticism of plagiarism. His overwhelming fear of criticism caused him to resist immediate publication of his work, later died in 1727.</li></li></ul><li>Refracting Telescope<br /><ul><li> He developed a theory of color based on the observation that a prism decomposes white light into the many colors that form the visible spectrum.
Also formulated an empirical law of cooling and studied the speed of sound.</li></li></ul><li>Gravity<br /><ul><li> gravity is the force that causes things to fall down.
It was the force of attraction between two objects.
an object with more matter mass exerted the greater force, or pulled smaller object toward it. That meant that the large mass of the earth pulled objects toward it.
Isaac calculated the force needed to keep the moon moving around the earth.</li></li></ul><li>First Law<br /><ul><li>states that an object that is not being pushed or pulled by some force will stay still, or will keep moving in a straight line at a steady speed.
means that there is a natural tendency of objects to keep on doing what they're doing. All objects resist changes in their state of motion.</li></li></ul><li>Second Law<br /><ul><li>An object accelerates in the direction the force is moving it.
that heavier objects require more force to move the same distance as lighter objects. Newton used his theory in a mathematical equation, which is expressed forced is equaled to mass time’s acceleration.</li></ul>F = Mass x Acceleration<br />
Third Law<br /><ul><li>That if an object is pushed or pulled, it will push or pull equally in the opposite direction.
That for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.</li></li></ul><li>Today<br /><ul><li>Isaac Newton’s calculations changed the way people understood the universe.
He proved that the planets were held in place by the sun’s gravity.
He also showed that the force of gravity was affected by distance and by mass. </li></li></ul><li>Thank You <br />
