Abstract: Kate pendulum is an accurate and ingenious experimental method to measure the

acceleration of gravity. In this paper,based on the principle,the model of Kate pendulum is

introduced,the experimental method is summed up,some common experimental errors are pointed out,and

the analysis is given so as to guide the ex- perimenters to pay attention to understand the

experimental principles and avoids going into the experimental errors.

Key words: Kate pendulum, acceleration of gravity, conjugate point, period
