About This Product
The pendulum is swung from one knife edge and then reversed onto the other, and the weights are moved until both periods are equal. The distance between the knife edges then equals the length of the equivalent simple pendulum, which gives g without needing to locate the centre of gravity. The Kater's Reversible Pendulum can be supplied on export terms to Latvia, Guyana, Maldives, Solomon Islands and South Korea.
Frequently Asked Questions
Why does Kater’s Reversible Pendulum have two knife edges?
It is swung from each knife edge in turn. When the periods match, the knife-edge separation equals the equivalent simple pendulum length, which is used to calculate g.
