Weight

Weight (Mass)
2
Mass is a measure of how much matter an object
has. Weight is a measure of how strongly gravity
pulls on that matter. Thus if you were to travel
to the moon your weight would change because the
pull of gravity is weaker there than on Earth
but, your mass would stay the same because you
are still made up of the same amount of matter.
