Sir Isaac Newton

           Sir Isaac Newton ( 25 December 1642 - 20 March 1726) was an English physicist and mathematician who is widely recognised as one of the most influential scientists of all time and a key figure in the scientific revolution.

           Eventually Newton's genius came to be widely known. His three laws of motion i.e, "Inertia", "Acceleration", and "Action and Reaction" remain a cornerstone of modern physics. His law of universal gravitation laid forth the theory that all particles in the universe exerted some gravitational force. In Newton's view, gravitational force was everywhere, from an apple falling from a tree, to the moon being kept in orbit by its mutual attraction with Earth. While imperfect, his law was later altered significantly by Einstein's theory of relativity -- Newton's conception of universal gravitation dominated physics for more than two centuries.

Newton's Laws:

  • Newton's First Law Of Motion: "Every object is in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it".

  • Newton's Second Law Of Motion: "The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object".

  • Newton's Third Law Of Motion: "For every action there is an equal and opposite reaction".

  • Newton's Law Of Universal Gravitation: "Any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them".

  • Newton's Law Of Cooling: "The rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings".
