CIE iGCSE Co-Ordinated Science P1.3 Mass and weight Exam Style Questions Paper 2
▶️ Answer/Explanation
Mass is the amount of matter in the object, and does not change with location.
Weight is calculated using \(W = mg\), and depends on gravitational field strength \(g\).
Since \(g\) is greater at the North Pole, weight increases while mass stays the same.

✅ Answer: (C)
Question
A rope is used to pull a block of mass 25 kg up a slope from point X to point Y.
Three distances are shown on the diagram.
The gravitational field strength g is 10 N/ kg.
What is the increase in gravitational potential energy of the block?
(A) 125 J
(B) 750 J
(C) 1000 J
(D) 1250 J
▶️Answer/Explanation
Ans: B
Question
The gravitational field strength at the Earth’s North Pole is greater than at the Equator.
An object is moved from the Equator to the North Pole.
What effect, if any, does this have on the mass and on the weight of the object?
▶️Answer/Explanation
Ans: C
