IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
Friction acts as a resistance force that reduces the motion of an object, eventually causing it to come to a stop. In a perpetual motion machine, which is a hypothetical device that can operate indefinitely without an energy source, friction would gradually slow down the machine and prevent it from achieving perpetual motion. Essentially, friction prevents perpetual motion by converting the machine's kinetic energy into heat.
Perpetual motion machines of the first kind are hypothetical machines that violate the first or second law of thermodynamics by producing energy without any external source. Perpetual motion machines of the second kind are also hypothetical, but they generate energy by utilizing an external source and converting some of it into work without depleting the source. Both types of machines are not possible based on our current understanding of physics.
There is no conclusive evidence of a perpetual motion machine being successfully invented. Such a machine would violate the laws of thermodynamics, specifically the conservation of energy. Many attempts to create perpetual motion machines have failed to provide sustained motion without an external energy source.
Perpetual motion machines do not exist. If they did we would not be paying almost $3.00/gallon for gasoline, as a perpetual motion machine implies free energy. Newton's laws tell us that is not possible. For further explanation read up on Newton's laws of motion and thermodynamics
Machines that experience friction are simply called frictional machines or machines subject to friction. Frictional forces resist the motion or relative motion of surfaces in contact, causing resistance and heat generation in the process.
Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.

Lots of people who don't understand thermodynamics very well. (Perpetual motion machines are not possible.)
Perpetual motion machines are theoretical only. No one has actually invented one. A perpetual motion machine would have to be able to provide its own source of energy to continue operating.
Perpetual motion is impossible if there is any friction, or any other removal of linerar or angular momentum.
Perpetual motion machines have, to date, always been a disappointment.

No, an automobile engine is not a perpetual motion machine. It relies on fuel combustion to produce energy, which is not a perpetual source. Perpetual motion machines are theoretical devices that can operate indefinitely without an external source of energy, which violates the laws of thermodynamics.
Perpetual motion. This answer is more related to the question "What do all machines DO NOT HAVE.
