1Calculate the mass that a person can lift on the Moon if he or she can lift a mass of 100 kg on the Earth. (Acceleration due to gravity of the Moon is \( 1.63\ \text{m/s}^2 \) and of the Earth is \( 9.8\ \text{m/s}^2 \).)
2For the base and the top of a mountain, where is the acceleration due to gravity less and where is it more? What is the difference in the weight of an object at those places?
3What is mass? Why does it not change from place to place?
4Why is weight a vector quantity?
5Write four differences between mass and weight.
6Why does an object weigh more at the poles than at the equator?
7Find the weight of a person of mass 60 kg on the Earth (\( g = 9.8\ \text{m/s}^2 \)) and on the Moon (\( g = 1.63\ \text{m/s}^2 \)).
8Why can a person jump higher on the Moon than on the Earth?
9Why is it easier to lift a small stone than a big one?
