Why is Newton’s cradle (Newton’s balls) described as an “almost-ideal” closed system? Explain your reasoning in one or two sentences.(2 points)

Question

And write like a fifth grader

Answer 1

Newton's cradle is almost-ideal because it only works when nothing else is moving or interfering with it. It's like playing a game where you can only win if you're really careful and don't let anything else get in the way.
