Quick explanation

Calculate the average for a small distance and a short time interval by measuring multiple values, including the oscillation period of a pendulum

  • This point belongs to Physical quantities and measurement techniques, especially Physical quantities and measurement techniques outcomes.
  • You need to be able to calculate the average for a small distance and a short time interval by measuring multiple values, including the oscillation period of a pendulum.
  • The key ideas to know are Determine and Calculate.
  • Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.

Method

Pendulum Experiment Method

1. Set up a pendulum with a known length. 2. Use a stopwatch to measure the time taken for 10 complete oscillations. 3. Repeat the measurement three times for accuracy. 4. Calculate the average time for one oscillation.

  1. a

    State the independent variable in this experiment.

    Aim for approximately 1 distinct marking point.
