Newton's Laws

Newton's laws of motion are three physical laws which provide relationships between the forces acting on a body and the motion of the body, first compiled by Sir Isaac Newton. Newton's laws were first published together in his work Philosophiae Naturalis Principia Mathematica (1687). The laws form the basis for classical mechanics. Newton used them to explain many results concerning the motion of physical objects. In the third volume of the text, he showed that the laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion.

The laws enunciated by Isaac Newton (c1690) that elucidated the laws of motion and confirmed the concept of mass and thus helped initiate the modern scientific era. He invented the (Newtonian ) refracting telescope.
