Newton’s Laws of Motion
Newton’s laws of motionFrom  Wikipedia, the  free encyclopediaFor  other  uses, see Laws of motion.Newton’s laws   of  motion are  three  physical  laws  that,  together, laid the foundation for classical mechanics.  They  describe the relationship between a  body  and  the  forces  acting  upon  it,  and  its  motion  in  response  to  those forces.  They have been expressed in several different ways, over nearly three centuries,[1] and can be summarised  as follows.First law  :  When  viewed in an inertial  reference frame,  an object  eithers  re- mains  at  rest  or continues  to  move at  a constant  velocity,  unless  acted upon by an external  force.[2][3]Second law  : The vector sum of the external  forces F on an object is equal to the  mass m of that object  multiplied  by the  acceleration  vector  a of the object:  F = ma.Third law  : When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.The three laws of motion were first compiled by Isaac Newton in his Philosophi Naturalis Principia Mathematica (Mathematical Principles  of Natural Philoso- phy),  first published  in 1687.[4] Newton  used them  to explain  and  investigate the  motion  of many  physical  objects  and  systems.[5] For example,  in the  third volume of the  text,  Newton  showed that these  laws of motion,  combined  with his law of universal  gravitation, explained  Kepler’s laws of planetary motion.Contents1   Overview         22   Newton’s first  law         33   Newton’s second law         43.1         Impulse   .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .         43.2         Variable-mass systems   .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .         54   Newton’s third law         55   History         65.1         Newton’s 1st Law .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .  .        6
