• A perpetual motion machine tries to produce energy without any energy input. • There are two main types: • Type I: Produces energy from nothing, violating the First Law of Thermodynamics (Conservation of Energy). • Type II: Converts all heat into work with 100% efficiency, violating the Second Law of Thermodynamics. 2. Why It’s Impossible • In the real world, there is always friction, air resistance, and heat loss, which continuously drain energy from the system. • Therefore, no machine can mo
