Problem
An explorer of mass 75 kg lands on the Moon for a scientific survey.
(i) Calculate the explorer’s weight on the Earth. Take the value of the acceleration due to gravity on the Earth as 9.8ms−2.
(ii) The acceleration due to gravity on the Moon is 1.6ms−2. Find the explorer’s weight on the Moon.
(iii) Determine the factor by which the explorer’s weight changes when moving from the Earth to the Moon.
(iv) If the explorer uses a bathroom scale calibrated on the Earth, what reading (in newtons) should be expected when he stands on it on the Moon? Justify your answer briefly.
