Mass Density

Mass density is a measure of how much mass (or material) is packed into a certain volume of a substance. It is calculated by dividing the mass of an object or material by its volume. For example, if you have two objects of the same size, but one is made of a heavier material like iron and the other of wood, the iron object has a higher mass density because it contains more mass in the same space. Density helps us understand how compact or heavy a material is, influencing its behavior and suitability for various uses.
