inertial
Opposing change naturally
Inertial relates to inertia—the tendency of objects to resist changes in motion.
In physics, an inertial frame of reference is one where Newton's laws hold without correction for acceleration.
Inertial navigation systems track movement using accelerometers and gyroscopes rather than external signals: The submarine relied on inertial guidance when submerged.
