Sir Isaac Newton His life and accomplishments By Kelsey Zolac

Facts  Isaac Newton was born on January 4, 1643  Born in Woolsthrope, Lincolnshire, England, UK  Died on March 31, 1727, in London, England  Was a Philosopher, Mathematician, Astronomer, Physicist, and Scientist  Was abandoned by mother and left with maternal grandmother until age 12

More Facts  Went to the University of Cambridge, Trinity College, and The King’s School  His love for science did not go unnoticed  Graduated with no honors or distinctions  Earned the title of scholar  In 1667 he was elected a minor fellow at Trinity College

Accomplishments  Invented the reflecting telescope in 1668  In 1687 this magnum opus – Philosophiæ Naturalis Principia Mathematica was published  Sir Newton also discovered gravity.

Laws of Motion  The Laws of Motion are defined as “The three laws that govern the motion of material objects”  In Philosophiæ Naturalis Principia Mathematica Sir Isaac Newton formulated his Three Laws of Motion.

First Law of Motion “ An object in motion stays in motion (same speed and direction) unless acted upon by an unbalanced force. An object at rest stays at rest unless acted upon by an unbalanced force.”

Example of Law 1 An example of this law is a car driving at a constant speed in one direction then hitting a brick wall. In this case the car was an object in motion until it hit the brick wall, the unbalanced force.

Second Law of Motion The second Law of Motion says, “ Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).” F=MA

Example of Law 2 An example of Law 2 is when someone is trying to push a car, but can not due to the fact the car has a greater mass than the person, and the person isn’t pushing hard enough.

Third Law of Motion “For every action there is an equal and opposite re-action,” is the third law of motion.

Example of Third Law An example of the third Law of Motion is a balloon releasing air. The air is let out in the opposite direction the balloon itself is going.

Gravity  Sir Newton discovered gravity when he saw an apple fall from a tree.  Realized some force must be acting upon the apple to make it fall  Newton used the idea of gravity to explain the astronomical observations of Kepler

Conclusion  Sir Isaac Newton discovered some of the biggest things in science such as gravity and the Laws of Motion.  His findings will be taught to many generations to come
