a swinging pendulum
The pendulum will lose energy, due to friction.
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
Because of energy loss via friction.
A swinging pendulum will eventually stop because of friction with the air.
Obviously, it will stop after sometime , after swinging. It is because we cannot apply energy continuously to the swinging pendulum.

At its lowest point
A swinging pendulum demonstrates primarily two types of energy - kinetic energy when the pendulum is in motion, and potential energy - based on how high it is above the mid-point of the swing. If not for friction, a pendulum would continue to swing forever, with the sum of the kinetic and potential energy remaining constant but the distribution between the two constantly changing as the pendulum moved through its swings.
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).
As the pendulum stops swinging, its maximum kinetic energy (the initial energy at the beginning of the swing) decreases, and its potential energy increases. Once the pendulum stops, it will have zero kinetic energy and maximum potential energy.
A pendulum does not keep swinging because the kinetic energy that it has as it swings is detracted from somewhat by the air. This may be easier to see with a comparison to friction. Air resistance acts on a pendulum swinging through air just as friction acts on an object sliding across a surface, causing it to come to a halt.

Is law catalyst for starting the pendulum swinging? or is ethics? politics?
A swinging pendulum will eventually stop because of friction with the air.
If a pendulum is at its center position, then there are two possibilities: 1). It may be swinging. Then its kinetic energy is maximum and its potential energy is zero. 2). It may be stopped altogether. Then it has no energy at all.
