a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
A force that opposes motion between two surfaces that are in contact.
the degree of compactness of a substance.
An object's change in position relative to a reference point.
A location to which another location is compared.
