Newton's law of motion

 Newton's three laws of motion: 

  1. Newton's first law of motion . It states that everybody continues in the state of rest or of uniform      motion, in a straight line, unless it is acted upon by same external force.

  2. Newton's second law of motion . It states that the rate of change of momentum directly               propotional to the impressed force, and takes place in the same direction, in which the force acts.  

  3. Newton's third law of motion . It states that  to every action, there is always an equal and opposite reaction.
