A single pendulum is a device capable of generating a reciprocating swing. A single endless pendulum or a non-stretchable string is suspended at a certain point in the gravitational field, and the other end is fixed with a heavy ball to form a pendulum. If the ball is only limited to swing in a vertical plane, it is a flat pendulum. If the ball swing is not limited to a vertical plane, it is a spherical pendulum.
The approximate period formula for the single pendulum motion is: T = 2π √ (L / g). Where L is the pendulum length and g is the local gravitational acceleration.
Under the action of gravity, it can wrap around a rigid body that oscillates through a certain fixed horizontal axis. That is, the complex pendulum is a dynamic motion system in which a rigid body is slightly oscillated under the action of gravity by a fixed horizontal axis. Also known as physical pendulum.
