1.	(a) Distinguish between inertial and gravitational mass. (b) Which is more fundamental -mass or weight- and why ? (c ) Why moon travellers load heavy weights at their back before landing on the moon ?
Answer» Solution :(b) Mass is more FUNDAMENTAL than weight because the mass of a body always remains samewhereas the weight of a body varies from place to place. (c ) As the value of g is very small on the moon the travellers FEEL weightless. To overcome this weightless, they CARRY HEAVY bags.
