Inertialess is a term used in physics and engineering to describe a hypothetical object or system that does not exhibit inertia. Inertia is the property of matter that resists changes in its state of motion. An inertial object, when at rest, tends to stay at rest, and when in motion, tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This fundamental concept is captured by Newton's first law of motion.

An object or system that is inertialess, in contrast, would have no resistance to changes in its velocity. This means it could instantaneously accelerate or decelerate without any force being applied, or it could change its direction of motion without any torque. Such a concept deviates significantly from our understanding of the physical universe as described by classical mechanics and is not observed in any real-world phenomena.

The idea of inertialessness often arises in theoretical discussions or thought experiments where scientists explore the boundaries of physical laws. For instance, it might be considered in scenarios involving hypothetical faster-than-light travel or in discussions about the nature of mass and its relationship to motion. However, it is crucial to understand that inertialessness is a theoretical construct and not a description of any known physical entity. All observed matter possesses inertia, which is directly proportional to its mass.
