Why perpetual motion don't work?

Perpetual motion machines violate the laws of thermodynamics, particularly the first and second laws. The first law states that energy cannot be created or destroyed, meaning a machine cannot generate more energy than it consumes. The second law posits that energy transformations are not 100% efficient, leading to inevitable energy loss as heat, which prevents a machine from operating indefinitely without an external energy source. Therefore, perpetual motion is impossible within the established framework of physics.
