Definition: In physics, "driftlessness" refers to a state of motion in which an object moves in a straight line without encountering any obstacles or changes in its direction. It is a fundamental property of most objects and can be described using the concept of velocity. The presence of such a state of motion suggests that the object's movement is not influenced by external forces, such as gravity or friction. In physics terms, this means that the motion of an object is entirely determined by its own internal properties,
