I need more context. Is this a math class or a physics class?
Assuming ordinary unaccelerated terrestrial situations:
-- There is a pretty close correspondence between weight
and mass.
-- For almost every math problem involving mass there is
a corresponding math problem involving weight (or |weight|).
-- So I don't see why the question of mass versus weight
needs to come up.
OTOH in a physics class, or if the math book starts throwing
around physics equations (e.g. F=ma) or starts asking about
weightless astronauts, that's a horse of a different color.
