Can you give three points of different between mass and weight ? How much would a 70 kg astronaut weight on the moon?

70 kg. Mass is a measure of the particles that makes up an object and the composition of the object does not change on the moon. However, the object's weight will change on the moon, just as it appears to change in an elevator. The acceleration due to gravity on the earth is approximately 9.8 m/s^2, depending upon where an object is located. On the moon, the acceleration due to the moon's gravity is 1.6 m/s^2, which is approximately 1/6 that on the earth. Since an object's weight is dependent upon the pull of gravity, the object's weight will change with the pull of gravity. Since the moon does not strong gravity pull as earth, the object would weigh approximately 6 times more on the earth than on the moon. But the mass doesn't change. Thus a 70-kg object on the moon is still a 70-kg object on the earth.
