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