When there is friction - as is usually the case - motion will eventually stop.
IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
No friction, in other words a vacuum.
there is no such thing aas a frictionless object (Perpetual motion machine) so friction still effects it
Perpetual motion machine is impossible because of the loss of energy due to friction or some other factors. This becomes clear in case of heat engine too. Certain amount of energy will be lost in irreversible way. Hence perpetual motion becomes impossible.

Perpetual motion is impossible if there is any friction, or any other removal of linerar or angular momentum.
Perpetual motion machines are an impossibility. Energy conversion is never 100% efficient. Even if it were, friction is never zero.

it affects motion by friction a friction pull it down or up

Perpetual motion would only work in a perfect environment - perfect vacuum - zero friction, zero resistance. The best we can hope for is to minimize the input energy - increase efficiency...
Some energy will always be lost due to different factors such as friction.
Friction makes things slow down.
