Investigating the oscillation period of a pendulum.

Method

Pendulum Experiment Method

To measure the period of a pendulum, set up a pendulum of known length. Use a stopwatch to time how long it takes for the pendulum to complete 10 oscillations. Repeat this measurement three times for accuracy.

  1. a

    State the independent variable in this experiment.

    Aim for approximately 1 distinct marking point.
