   He was raised by his grandmother
       Early Years (con’t)
   AT age Twelve, he was enrolled in King
    School at Grantham
   Henry Stokes and Mr. Clark inspired
    Newton to become a scientist

   Entered Cambridge University in 1661
   Received a fellowship at Trinity College
    in 1967
   Became a Lucasion Professor of
    mathematics in 1669, and held it for 32
   Elected as a member of Parliament fo
    the university of Cambridge.
    Newton’s Greatest Works
   Philosophiae Naturalis Principia
     (Mathematical Principles of Natural
          Natural Philosophy was the study of the laws of
     This book was divided into an introduction
      and three books
 Philosophiae Naturalis
 Book 1 states, the foundation of the
  science of mathematics (Hall)
 Book 2, inaugurates the theory of fluids
 Book 3, shows the laws of gravitation at
  work in the universe
   Founder of Calculus
   Newton’s contributions to mathematics:
     differentiation
     integration
     Fluxions
     Inverfluxion
Newton’s Law of Gravitation
   Every particle in the Universe attracts
    every other particle in the Universe with
    a force that depends on the product of
    the two particle masses divided by the
    square of the distance between them.
   He formulated a Universal Gravitational
    Constant called the G-Constant. It’s
    value is 6.670 x10^-8cm^3/gsec^2
       Newton’s First Law
   Every body continues in rest or in
    uniform motion in a straight line, unless
    it is compelled to change that state by
    forces impressed upon it (Christianson
     Newton’s Second Law
   The change in motion is proportional to
    the motive force impressed and is made
    in the direction of the right line in which
    that force is impressed.
       Newton’s Third Law
   To every action there is always an
    equal reaction or, the mutual actions of
    two bodies upon each other are always
    equal and directed to contrary parts.
