From the second law of thermodynamics, "It is impossible to convert heat completely into work in a cyclic process." Thus, energy in a system is gradually lost. Because of this, the energy will eventually run out (though it may take a very long time), and perpetual motion is impossible.
Because perpetual motion can not happen
Theoretically it is impossible. Many have tried and many continue to attempt to develop a perpetual motion machine. Only if there is no friction and no energy is lost to the surroundings, would perpetual motion be possible... No. Such machines are not possible, although until the end of mankind people will perpetually try to imagine or create one.
No one, and no one ever will, since perpetual motion machines are a scientific impossibility.
Perpetual Motion Machine
Perpetual motion would only fit the principle of the conservation of energy if it was a machine that moved that did not have any friction or produce any sound or produce any form of heat or energy that could be lost in any way. Since no such machine is possible to create, as far as we know, perpetual motion is declared an impossibility and does NOT fit the principle of the conservation of energy. Energy will undoubtedly be lost somewhere in a moving system.

Perpetual Motion Machine.
Its a machine that has to be started but doesn't need to be restarted.
There is no answer to your question because a perpetual motion machine is impossible. If one could be built, its own motion would be considered work.
A perpetual motion machine of the first kind it what we usually mean by a perpetual motion machine. A device which once started will continue to run and do useful work forever without the need to add energy to keep it going. The laws of physics make such a device impossible.
it depends on what you use to build it
