Just like the first law of motion and object at rest remains at rest unless acted uponan unbanlaced foce
When the ground shakes, the suspended weight of the seismograph, because of its inertia, scarcely moves, but the shaking motion is transmitted to the marker, which leaves a record on the drum.
The seismometer does move during an earthquake. The simplest seismograph consists of a bed that a band of graph paper is pulled over and a suspended pen that touches the paper. The paper moves under the pen. The pen is fairly stationary because of its inertia. When the earth shakes, the pen traces a line that corresponds to the movement of the bed under it.
The pendulum is made of weights that are suspended on springs. The weight suspended on the springs creates enough inertia so that the pendulum is unmoved during an earthquake. The truth is, if there is enough force to overcome the inertia of the suspended weights, it will move.
a seismograph measures how big an earthquake is. it acts like a swingset. the top of the seismograph stays in 1 place. Its mainly the pendulum
the pen...its the paper that moves
It's broken.
A seismograph is the device that scientists use to measure earthquakes. The goal of a seismograph is to accurately record the motion of the ground during a quake

earthquakes are measured by seismic waves so scientists use a seismograph. there are a bunch of seismographs at a station and each one records the same stuff according to the p, s, and surface waves.
It is Seismograph!.!

explain why a seismograph would not work if the pen vibrated along with the rest of the machine.
Well you know when you write a sentence, the paper stays in one place while your hand moves the pen. But in a seismograph, it's the pen that remains stationary while the paper moves. Why is this? All seismographs make use of a basic principle of physics: Whether it is moving or at rest, every object resists any change to its motion. A seismograph's heavy weight resists motion during a quake. But the rest of the seismograph is anchored to the ground and vibrates when seismic waves arrive.

A seismometer (replacing the outdated term seismograph), but other instruments may also respond to an earthquake. The simplest example of a seismograph is a pendulum.
The part of the seismograph that moves during an earthquake is called the pen.
The mass of the pendulum, the length of string, and the initial displacement from the rest position.

Scientists measure the magnitude (energy) of an earthquake using a seismograph (sort of sensitive pendulum that records the shaking of the earth).
