The massof an object is how much matter there is in the object.
You weight it.
mass = volume X density
Mass.
The amount of matter (mass) in a certain amount of space (Volume).
It has like more dense
density
amount of mass contained in a certain space
Amount of mass contained in a certain space There is also linear density, mass per unit length. Sometimes density is a force per unit of volume instead of a mass per unit of volume.
Mass per unit volume is the object's "Density".
Density is the ratio between the mass and volume, at a given temperature.
Mass is the amount of matter in an object, while weight is the gravitational force applied to an object. Mass is a function of weight since weight it determined by the amount of force placed on an object of a certain mass.
Density is the amount of mass in a certain unit volume of a substance (Density equals mass divided by volume).
