Simple Pendulum Properties

Key Characteristics

  • • Period depends only on length and gravity
  • • Independent of mass (Galileo's discovery)
  • • Independent of amplitude (small angles only)
  • • Used in clocks for timekeeping

Applications

  • • Measuring local gravity (gravimeters)
  • • Pendulum clocks (grandfather clocks)
  • • Seismometers for earthquake detection
  • • Foucault pendulum (Earth's rotation)
