This section is concerned with "missing energy" that can be stored in an object as internal energy. Should there be a similar concern about "missing momentum" and "internal momentum"? (A) Yes, but the effects will be much smaller because momentum is proportional to elocity whereas energy is proportional to velocity squared. (B) Yes, but the effects can be ignored because physicists are only concerned with systems where momentum is conserved. (C) No, because momentum is a vector whereas energy is a scalar. (D) No, as long as "potential momentum" is not introduced.

							The correct option is (D).
Without any applied external force to a system, the change in momentum of the system is zero. But if a term “potential momentum” is present then the applied external force to a system is equal to change in momentum of the system plus missing momentum of the system. Thus the system acted by the without any external force, then the change in momentum will be equal to the negative of missing momentum of the system. But in reality this is not possible, since the term “potential momentum” is not introduced yet. Therefore there is no similar concern about “missing momentum” and “internal momentum” as long as “potential momentum” is not introduced. Therefore option (D) is correct.
