Definition: Unfluctuant is a mathematical concept in mathematics that refers to a quantity or object that remains constant over time. It can be defined as an attribute of a physical system that does not change with respect to time, and it describes how quickly a quantity changes when compared to its original value. In physics, unfluctuant quantities are often used to describe the state of motion of objects in a closed system where all forces acting on them are constant. For example, an object's velocity can remain
