Question

What is the principle of compound pendulum?

Answer 1

The principle of the compound pendulum:

1. A compound pendulum consists of an extended mass that oscillates freely around a horizontal axis.
2. Kater's pendulum is a reversible compound pendulum designed to determine the value of $g$, or gravity's acceleration.
3. The principle of compound pendulum states that the time period and frequency of the compound pendulum depends on the length of gyration, the moment of inertia and the mass of the pendulum as well as gravitational acceleration.
