Which way is the momentum occuring if a child is riding a merry go round at a constant speed. So for example at each 4 "sides" of the merry go round which direction is momentum .
I know the velocity is always tangent to the circle at a specific point. does the momentum go in the same direction as the velocity. or no because the force is pointing in towards the center

and to go along with that. if velocity and mass are constant does that mean the change in magnitude of the momentum is 0?
