I know a high school student who has this question. My first thought was that it does not hold if the mass is changing with time. I was thinking of the situation of a snowball rolling down a mountain picking up more snow as it rolls to the bottom. There is obviously mass gained so does Newton's Second Law hold for this situation at the very basic level (for a high school physics question)? If it does, can you think of a situation where it wouldn't hold? Remember that this is a high school introductory course in Physics
