Problem
List any two differences between mass and weight of a body with reference to (i) their nature and (ii) their dependence on location.Intuitive explanation
Mass and weight are often confused, but they're fundamentally different properties. Mass is the amount of matter in an object—an intrinsic, unchanging property—while weight is the gravitational force acting on that mass, which depends on local gravity. The key insight is that mass stays the same everywhere (on Earth, the Moon, or in space), but weight changes dramatically depending on the gravitational field strength at your location. Understanding this distinction explains why astronauts are "weightless" in orbit despite having the same mass.
