A: Mass is a measure of the amount of matter contained by an object, while weight is a measure of the gravitational pull on an object. As the gravitational force exerted by Earth is the constant upon which mass is calculated, the values of an object's mass and weight on Earth are approximately equal depending on geographic location. read more
This equation explains the relationship between mass, a property of an object, and weight, which is considered a force. If you went to the moon, your mass would be unchanged, but your weight would be 1/6 less because the force of gravity on the moon is 1/6 of the force of gravity on earth. read more
