					Force and Motion
                               More than three hundred
                                 years ago, an English
                               mathematician, scientist,
                              and astronomer named Sir
                               Isaac Newton used three
                             laws to explain how objects
                                        move.
Sir Isaac Newton 1642-1727
 Newton’s first law of motion states that an
  object at rest tends to stay at rest and an
  object in motion tends to stay in motion,
unless the object is acted upon by an outside
                     force.
Newton’s second law of motion states that a
change in an object’s motion depends on the
 object’s own mass and the strength of the
            force acting upon it.
Newton’s third law of motion states that for
every action there is an equal and opposite
                 reaction.
Newton’s first law of motion states that an object at rest tends
to stay at rest and an object in motion tends to stay in motion,
      unless the object is acted upon by an outside force.

         there is an equal and opposite reaction.
