Newton’s Laws of Motion:-

Newton’s Laws of Motion:-
   These principles can be wrapped up in just three statements that were clearly stated for the first time by Sir Isaac Newton (1642-1727), who published them in 1687 in his philosophiae Naturalis principia Mathematica (“Mathematical Principles of Natural Philosophy”). These three statements are called  Newton’s Laws of Motion. The first low stated that “When the net force on a body is zero, its motion doesn’t change”. The second law relates the force to acceleration when the net force is not zero. The third law is a relationship between the forces that two interacting bodies exert on each other. (Newton used the ideas and observation of many scientists before him, including Copernicus, Brahe, Kepler, and especially Galileo Galilei, who died the same year Newton was born). Newton’s laws are empirical laws, deduced from experiments. Newton’s laws are adequate for speeds that are low compared with the speed of light when the bodies move with the speed of light then Newton’s laws failed like atomic particles in an accelerator relativistic mechanics developed by Albert Einstein is applicable.
