Which of the following will cause an increase in the mass of an object?

increase in the gravitational pull
decrease in the gravitational pull
increase in the amount of matter present in the object
decrease in the amount of matter present in the object

Increase the amount of matter present in the object

The mass of an object is a measure of the amount of matter present in the object. Mass is independent of the gravitational field strength; the dependency on gravitational field strength is that of weight. The other property characteristic to matter is the amount of space it occupies, also known as its volume. The ratio of these properties of matter, mass over volume, produces a characteristic property called density.
