A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
Is law catalyst for starting the pendulum swinging? or is ethics? politics?
Obviously, it will stop after sometime , after swinging. It is because we cannot apply energy continuously to the swinging pendulum.
-- its length (from the pivot to the center of mass of the swinging part) -- the local acceleration of gravity in the place where the pendulum is swinging
A clock pendulum swinging back and forth. A weight on a spring moving up and down.
That is the correct spelling of the word "swinging" (pendulum-like motion).
Pendulum
because it has to keep moving until it can't move no more
Most pendulums are operated by a spring, when the spring looses its tention it can no longer keep the pendulum swinging. Others may work on a different system but the system in not perpetual and will loose its ability to keep the pendulum swinging. As a point of interest you canot use a pendulum in space.

The period or frequency of the pendulum
Small: This is to ensure that the motion of the pendulum mostly stays along one direction, i.e. it is swinging back and forth as opposed to rotating or moving erratically. Only when the pendulum is moving in this manner can you say that it follows SHM - Simple Harmonic Motion (If that is the aim of the experiment)
It is known as the Pendulum.
