• Thus, the massof the object on earth is 1 2 k g. We know that the mass of the object remains the same through out the universe. Hence, mass of the object on the moon is also 1 2 k g. We know, weight of the object on the moon = 1 / 6 of the weight of the object on the earth. Therefore, W (m) = 1 / 6 × W (e) That is, W (m) = 1 / 6 × 1 2 0 N = 2 0 N
