Density describes the relationship between ____ and ____.
Mass and volume
400
Explain the difference between mass and weight.
Mass is a measurement of the amount of atoms that make up an object. Mass does not change when you go from earth to the moon. Weight is a measurement of the pull of gravity on an object. Weight will change when you go from the earth to the moon.
