Mass is the amount matter in an object. Mass is usually expressed in grams/pounds. For example, if you had a mass of 100 pounds and you went to the moon, you would still have â¦ a mass of 100 pounds, because there is 100 pounds of matter in you. However, your weight, or the gravitational pull on you, would change.
Matter is defined as anything that occupies space and has mass. Mass is a measure of an object's inertia. It is proportional to weight: the more mass an object has, the more weight it has.However, mass is not the same as weight.Weight is a force created by the action of gravity on a substance while mass is a measure of an object's resistance to change in motion.atter is defined as anything that occupies space and has mass.
