Mo8-L4b: What is the Law of Conservation of Momentum?





                                              Momentum Equation














































               An object’s momentum is in the same direction as its   Conservation of Momentum
               velocity.
                                                                  According to the law of conservation of momentum,
               According to Newton’s f rst law, if the net force on an   the total momentum of a group of objects stays the
               object is zero, neither its velocity nor its momentum   same unless outside forces such as friction act on
               change.
                                                                  the objects.
               Because momentum is the product of mass and
               velocity, the force on an object equals its change in
               momentum.
