This fundamental principle of physics is the basis behind the effectiveness of a seismometer.
A) The change of momentum of a body is proportional to the impulse impressed on the body, and happens along the straight line on which that impulse is impressed.
B) The mutual forces of action and reaction between two bodies are equal, opposite, and collinear.
C) Every body persists in its state of being at rest or of moving uniformly straight forward, except insofar as it is compelled to change its state by force impressed.
D) To every action there is always an equal and opposite reaction.

A seismometer works on the principle of inertia, which is described by Newton's first law of motion. It states that an object will remain at rest or in uniform motion unless acted upon by an external force. This principle allows the seismometer's mass to remain stationary while the Earth moves during an earthquake, enabling the detection of seismic waves.
