What is the definition of density?

Density is a measure of how compact the mass in a substance or object is. The density of an object or substance can be calculated from this equation: density in kilograms per meter cubed is equal to mass in kilograms, divided by volume in meters cubed. Or in other words, density is mass spread out over a volume.

Also question is, what is the definition of density in science?

Density is a measure of mass per unit of volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

What is the definition of density for kids?

Every object on earth is made of atoms. Gravity pulls these atoms to the earth. You can measure the pull of gravity on an object – we call that measurement weight. Density is how close together the molecules of a substance are or how much mass a substance has in a given space.
