Detailed explanation-1: -Mass of an object is a measure of the amount of matter present in that object. The amount of matter present in an object remains same whether the object is on moon or earth. Therefore, mass of an object measured on the moon is same as that measured on the earth.
Detailed explanation-2: -For instance, on Earth, a 5.0-kg object weighs 49 N; on the Moon, where g is 1.67m/s2 1.67 m/s 2, the object weighs 8.4 N. However, the mass of the object is still 5.0 kg on the Moon.
Detailed explanation-3: -The mass of an object remains the same on the earth and on any other planet. Therefore the mass of the body on the space will be 5 kg.
Detailed explanation-4: -The mass and weight of an object on earth are 5 kg and 49 N respectively. What will be their values on the moon? Assume that the acceleration due to gravity on the moon is 1/6th of that on the earth. Ans: 5 kg and 8.17 N.
Detailed explanation-5: -On moon, the mass of the object is 5 kg and the weight is 8.15 N.
