the mass of the object determines the amount of inertia in an object. Mass determines the amount of inertia an object has. It is an object's intrinsic property to resist change. the two main things are speed and velocity. You have to factor in a bunch of smaller things too, but those don't really have much effect.
Full Answer. The amount of an object's mass contained within the physical space it occupies, which is its volume, determines its density. Like weight, the density of an object is a different property than its mass. The density of an object is equal to its mass divided by its volume.
