Problem

A sack of rice is weighed on the surface of the Earth at a place where the value of

g

9.8\,\text{m/s}^2

. Answer the following: (i) Define mass and weight. (ii) If the weight of the sack is

147\,\text{N}

, calculate its mass. (iii) The same sack is taken to the Moon where

g = 1.63\,\text{m/s}^2

. Find its weight on the Moon. (iv) Will the mass of the sack change on the Moon? Give reason for your answer.
