What is a Perpetual Motion Machine?
Perpetual motion is the motion of bodies that continues forever. Thus, such a machine never stops.
The question is, are these machines possible? So, let us look at some of the criteria for its possibility.
- No two moving parts should touch other to avoid friction and loss of perpetual energy due to heat.
- Operation of the machine inside a vacuum to circumvent air friction.
- No sound should be made by the machine.

There are a lot of other laws and principles to obey. Thus, the possibility of a perpetual motion machine still remains a question.
