An ideal pendulum is one in which no air resistance or friction is present. Hence when set into motion it never loses energy to it's surrondings.
So when released, and left to swing, the energy potential it had get's convertedinto kinetic energy and therefore the pendulum swings. When it reaches it's amplitude(Highest swing) the energy is converted back to potential, and as it falls back to kinetic. As it is "ideal" it never loses energy to heat/ friction. Therefore, the conversion of kinetic energy to potential etc etc will always be constant and it will never stop.
Although in reality it is impossible to have an "ideal" pendulum, near ideal ones can be obtained by suspending the pendulum in a vacuum.

A heavier pendulum will swing longer due to its greater inertia.
The pendulum of a clock is the long weighted bar that swings back and forth in the case below the clock. It was discovered several hundred years ago that the time it takes for one swing of a particular pendulum is constant, no matter how big or small the swing is. It can, therefore, be used to measure time.

A pendulum
it all has to do with a pendulum when you swing back and forth you are using potenial and kinetic enery

if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
Gravity makes a pendulum swing back and forth. The object starts at one point, and then moves in a circular motion to the apex of it's next point. The kinetic energy becomes less and less as time goes on if no extra energy is added.

how is pendulum swing related to teaching process?
Every time the pendulum swings back and forth, some energy is lost to friction. Friction with air, and friction in the supporting string or whatever. If you manage to reduce this friction (for example, reduce air friction by making the pendulum swing in a vacuum), it will swing longer. However, you won't be able to reduce energy losses completely; it may swing longer, but not forever.
