👉 In physics, a "rissoid" is an object that behaves like a sphere when subjected to uniform circular motion. These objects are characterized by having a high density and low mass, making them very difficult to crush or break.
The term "rissoid" is derived from the Latin word "risus," which means "ring." In this context, "rissos" refers to a ring-like shape, and "rissodes" indicate that these objects are spherical in shape.
