Use datalogging equipment to either:

  • Measure the periods of a pendulum; and/or
  • Measure the acceleration of an Atwood's machine

to determine a local value for gravitational field strength, g


  • Develop an understanding of collecting and processing data in a way that improves accuracy

PH12-12/Gravitational fields

  • Apply qualitatively and quantitatively Newton’s Law of Universal Gravitation to:

    • Investigate the factors that affect the gravitational field strength
    • Predict the gravitational field strength at any point in a gravitational field, including at the surface of a planet (ACSPH094, ACSPH095, ACSPH097)
