simple pendulum

FIRST TEST  Maintain fixed the length and changing the amplitude of the oscillation. Record the results in a table.  The period increases, decreases or remains constant?  SECOND TEST Maintain fixed the amplitude of the oscillation and measure the period. Record the result in a table. Check the hypothesis.  The period of oscillations is proportional to the square root of the pendulum length. Use an Excel spreadsheet to analyse the results. http://www.esperimentifisica.cloud/phisics_laboratory/pendulum/pendulum.html
