What happens to momentum when an impulse acts on a system?

Question

Quizplus · Accepted Answer

According to the impulse-momentum theorem, an impulse acting on a system will change its momentum. Therefore, choice B is the correct answer. Choice A (momentum is conserved) is incorrect because momentum is only conserved in a closed system where no external forces act. Choice C (impulse does not affect momentum) is incorrect because impulse is defined as the change in momentum of a system, so it must affect momentum. Choice D (all of the above are possible) is incorrect because only choice B is correct.
