WebMomentum is only conserved if the total external force is zero. If the system you consider is large enough, then any forces will be internal, not external. This is shown in the following cartoon, which is of course not to scale. A car accelerates from rest. The momentum of the car is not conserved. Webmomentum is conserved in a closed system. If you consider only the ball as the system, then there's an external force from the spring on the ball, so the ball's momentum is not conserved. If you consider the wall and spring and ball as one system, then you have to … birmingham city university careers serviceWeb18 mrt. 2024 · The total angular momentum is the sum of the spin and orbital angular momenta for the electrons in an atom.
