Distinguish between mass density and weight density?

Answer 1

The difference is that the mass density not effect by gravity but weight density effect by gravity. for example if mass density cotn in earth equal to 20 kg/m3 and weight density equal to 196.2 N/m3 this cotn will change the weight density in the moon but mass density not change because gravity moon diffrent to gravity earth

mass density =mass/volume (no gravity)

weight density= (mass * gravity)/volume (gravity)

Answer 2

Mass density refers to the amount of mass per unit volume of a substance, usually expressed in units such as kg/m^3. Weight density, on the other hand, refers to the weight of a substance per unit volume and is influenced by the acceleration due to gravity, typically expressed in units like N/m^3 or lb/ft^3. Mass density remains constant regardless of location, while weight density can vary depending on the strength of gravity at a particular location.

Answer 3

Quite simply, mass density is mass per unit volume, and weight density is weight per unit volume. So it all comes down to understanding the difference between mass and weight.
