![]() State the precautions you would take for the experiment.Įnsure that the oscillation is steady before starting to time.Įnsure that the angular displacement of the bob is less than 10 degrees.ĭescribe how you would obtain experimentally accurate values for internal (external) diameter of a thick metal pipe. ![]() The period of the pendulum is given by average time for 20 oscillations divided by 20. ![]() The measurement is repeated and the average is calculated. When the oscillation is steady, the time taken for 20 oscillations is measured using a stopwatch. The simple pendulum is made to oscillate at a small angle. ![]() Describe an experiment to show how the period of pendulum can be determined
