One person slowly moved the paper past the pen, as the other hit the end of the table.The first trial represented a medium magnitude movement.
My results showed the trial with the greatest amplitude was trial three because the table was being hit with the most force, making the table and the pen move more than the other three trials.
The trial with the least amplitude was trial two because the table was hit with the least amount of pressure.
It can be used to repeat the experiment or to test other hypotheses in new experiments.
(Name)__________________ (Date)______________ Title: ______(the name of the lab or experiment) The purpose or problem states the reason(s) why you are doing the experiment.
Hypothesis: An increase in the magnitude of vibrations will result in an increase in amplitude of the seismograph.
Materials: clamp, metal bar, piece of string, rubber bands (2), table, pencil, two people Procedure: I laced a piece of paper directly beneath the pen and the clamp stand.
The second trial was the soft movement, and the third was the hardest, or the most forceful magnitude.
While looking at each individual seismograph, the greatest magnitude was observed and identified.
While observing the experiment, I noticed that the more vibrations or higher magnitude resulted in a higher amplitude on the seismograph.
The harder the table was being hit, the higher the amplitude rose. I believe the results are accurate because while the experiment was in progress, the frame moved at the same rate as the table.
