  How much would a 70 kg man weight in the moon? What would be his mass on the earth and on the moon? (Acceleration due to gravity on moon = 1.63 m/s2)

Answer:

                  Let us calculate the weight of the man on the moon. Mass of the man on the moon, m = 70 kg Acceleration due to gravity, g = 1.6 m/s We know that weight is given by Thus, the man weight 114.1 N on the moon. We know that the mass of a body is constant everywhere in universe. So, the mass of this man would be same on the earth as well as on the moon. Hence, the mass will be 70 kg on earth as well as on moon.
