What fundamental concept underpins the measurement capability of early devices like pendulums and seismometers?
Answer
The principle that mass resists changes in motion (Inertia)
The core concept underpinning early inertial measurement devices, such as seismometers and pendulums, is inertia—the property stating that an object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an external force.
