An inertia damper is a device that counters vibration using the effects of inertia and other forces and motion.
[1] The damper does not negate the forces but either absorbs or redirects them by other means.
Inertial compensators are also used in simulators or rides, making them more realistic by creating artificial sensations of acceleration and other movement.
The Disneyland ride “Star Tours: The Adventure Continues” is a fair example of this principle.
There are many types of physical devices that can act as inertia dampers: This physics-related article is a stub.
