Density

Real World Example

Imagine trying to pack a suitcase for a long trip and struggling to fit everything in. This is similar to the concept of density, where you're trying to fit as much mass (clothes and items) into a limited space (your suitcase). Just as packing more items into the same suitcase makes it feel heavier and more compact, increasing the mass within a given volume increases an object's density, showing how tightly matter is packed together.
