Why is perpetual motion impossible?

Perpetual motion is motion without end. Once an object begins to move, there should be no end to its movement. It should continue in its motion without ever stopping. On this earth, this would be impossible because of several reasons. First, if there is friction, that would cause energy to be lost and eventually the loss of energy will cause the object to stop its motion.

If such a machine were to work, there should be movement without the input of any energy. But this would go in direct opposition to the first law of thermodynamics, which is the law of the conservation of energy. The second law of thermodynamics is also a conflict as it says that energy cannot be created or lost. Only the energy that is currently available in the universe can be used and reused (with an accounting for loss). Thus, perpetual motion is not possible in our universe as we know it
