Newton’s Greatest Works Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) Natural Philosophy was the study of the laws of Nature This book was divided into an introduction and three books Philosophiae Naturalis Principia 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 Mathematics 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 292) 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.
