Abstract: A new method for measuring gravitational acceleration is designed by using parallel-axis theorem of rotary inertia.The source of uncertainty in the experiment is analyzed to improve the measurement accuracy.The measuring result agrees with the locality value of gravitational acceleration.
Key words: three-line pendulum, rotary inertia, parallel-axis theorem, gravitational acceleration
