Katers pendulum stopwatch meter scale and knife edges theory katers pendulum shown in fig 1 is a physical pendulum composed of a metal rod 120 m in length upon which are mounted a sliding metal weight w 1 a sliding wooden weight w 2 a small sliding metal cylinder w and two sliding knife edges k 1 and k 2 that face each other . Why we use katers pendulum katers pendulum can be used as a gravimeter for the measurement of the local acceleration due to gravity with the help of katers pendulum this measurement can be carried out with greater accuracy than an ordinary pendulum. The reversible pendulum katers pendulum has two pivot points on opposite sides of the centre of gravity from which the pendulum can be suspended as shown in fig 1 la and lb are the distance of the centre of gravity from pivot points a and b respectively following eq3 the time period about a and b can be written as 6 o2 e th
