Homogeneous Sphere

A homogeneous sphere is a perfectly round object made of material with a uniform density throughout, meaning its mass is evenly distributed. Imagine a solid ball of clay where every part weighs the same per volume. This uniformity simplifies calculations in physics and engineering because the entire object can be treated as if its properties are the same everywhere inside. Examples include some planets or models used to understand gravitational forces. The key aspect is that density remains constant from the center to the outer surface, making it an idealized but useful shape in scientific studies.
