A perpetual motion machine is impossible because it violates the laws of thermodynamics. The first law states that energy cannot be created or destroyed, so a machine cannot run forever without input. The second law states that no process is 100% efficient, as some energy is always lost as heat or friction. Together, these laws prove that a perpetual motion machine cannot exist in reality. #MechanicalEngineering #Thermodynamics #Engineering #engineeringmemes #instagramreels #EngineeringStudents
