Problem
(a) Define the terms (i) mass and (ii) weight.
(b) A student says, “An object has the same weight everywhere because its amount of matter does not change.” Identify the conceptual error in this statement and explain the correct idea in not more than three sentences.
(c) An object shows a reading of 49 N on a spring balance at the Earth’s surface. If the same object is taken to a planet where the acceleration due to gravity is one-sixth that of Earth, predict qualitatively (without calculation) how its weight will change and justify your answer.
