What happens to the frame of a seismograph when seismic waves arrive?
It moves with the same frequency and amplitude as the seismic waves, while the large mass suspended within it is damped from these oscillations due to it's own inertia. The relative movement between this stationary mass and the frame can then be recorded.
What machine detects earthquakes?
A seismometer (the term seismograph may be used to describe a seismometer combined with an instrument for recording and displaying the amplitude and frequency of the seismic waves that the seismometer measures). Please see the related link.
What are the functions of the seismograph?
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
What does a seismograph look like?
A seismograph typically consists of a base, a mass suspended on a spring, and a recording device for tracking ground motion caused by seismic waves. The mass remains stationary during ground motion, creating a relative motion that is recorded as a graph called a seismogram on the recording device.
Did choko invent the seismograph?
Yes, Choko did not invent the seismograph. The seismograph was invented by the Chinese polymath Zhang Heng in 132 AD during the Han Dynasty. Zhang Heng's seismograph could detect and record earthquakes from a distance.
Why does the pendulum of a seisomgraph remain at rest?
The pendulum of a seismograph remains at rest due to inertia. When there is no seismic activity, the pendulum stays stationary in its equilibrium position until external forces disrupt this balance. The motion of the pendulum when detecting seismic waves helps record and measure the intensity and duration of the earthquake.
The part of a seismograph that does NOT move during an earthquake?
The seismograph's mass, typically a heavy weight or pendulum, remains stationary during an earthquake. Its inertia allows it to stay in place while the ground moves. This mass is connected to a recording device that captures the motion caused by seismic waves during an earthquake.
What happens to the frame of a seismograph when seismic waves arrive?
It moves with the same frequency and amplitude as the seismic waves, while the large mass suspended within it is damped from these oscillations due to it's own inertia. The relative movement between this stationary mass and the frame can then be recorded.
Why a seismograph wouldn't work if the pen vibrated along with the rest of the machine?
explain why a seismograph would not work if the pen vibrated along with the rest of the machine.
How does a seismograph record seismic-waves?
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.

How does an old seismograph work?
The seismograph works as follows. A pen, along with a particular calculated amount of (small) weight is attached to a spring. The other end of the spring is attached to a heavy and stable(so that it can with stand the earthquakes) base support. When an earth quake occurs, the movement of the smaller weight is recorded on a roll of moving paper by the pen. Then the extent of the earthquake is measured by those graphs(seismographs).
What year was a seismograph made in?
The first seismograph was invented in 132 AD by Chinese astronomer Zhang Heng during the Han dynasty. It was a copper vessel with a pendulum mechanism that could detect and record earthquakes.
What affects a pendulum?
The mass of the pendulum, the length of string, and the initial displacement from the rest position.
Which part of the seismograph moves as the ground shakes during an earthquake?
The part of the seismograph that moves during an earthquake is called the pen.
How does part of the seismograph remain at rest during an earthquake?
pen
How do the cycles change when more mass present in a pendulum?
With more mass in a pendulum, the period of the pendulum (time taken for one complete cycle) remains the same as long as the length of the pendulum remains constant. However, a heavier mass will result in a slower swing due to increased inertia, which can affect the amplitude and frequency of the pendulum's motion.
