Question

An 80 kg patient went to a doctor . The doctor advised him to reduce his weight. Should the patient
plan to live on the moon so that his weight gets reduced? Explain your answer.

Answer 1

I think the patient should not plan to live on the moon. But in this case weight gets reduced:

$$W_E=mg_E=(80)(9.8)=784\ N$$

$$W_M=mg_M=(80)(1.6)=128\ N<W_E$$
