If we measured the mass of an object with an ordinary bathroom scale on Earth, on the Moon, and on Mars, we would find that it weighed most on Earth and least on the moon. In each case, the mass did not change, but the weight did. This is because the gravitational force of each planet is different, but the spring in the scale has not changed. For this reason, we use a balance to determine the mass of an object.
