Force
Sir Isaac Newton described the motion of all objects using the concepts of inertia and force, and in doing so he found they obey certain conservation laws. In 1687, Newton published his thesis "Philosophiæ Naturalis Principia Mathematica". In this work Newton set out three laws of motion that to this day are the way forces are described in physics.
History of centrifugal and centripetal forces
Christiaan Huygens coined the term "centrifugal force" in his 1659 "De Vi Centrifuga" and wrote of it in his 1673 "Horologium Oscillatorium" on pendulums. Isaac Newton coined the term "centripetal force" ("vis centripita") in his discussions of gravity in his 1684 "De Motu Corporum".
