A student hits a hockey puck with a hockey stick and the puck speeds up. Another student claims that the student broke the Law of Conservation of Momentum
because the puck gained momentum. Which of the following is the best
explanation of why the Law is not broken in this closed system?
The Law of Conservation of Momentum only applies for objects of equal mass.
The momentum of the puck is the same before and after the hockey stick hits
the puck.
The hockey stick loses as much momentum as the puck gained.
The force on the puck cancels the force on the hockey stick because the forces
are equal and opposite.
