It is the classic way of showing the interplay between potential energy and kinetic energy, along with the effects of nearly-elastic collisions. Easy to assemble and has a fun value also. It Include Base Plate, Vertical Stand, Top horizontal plate ,Fly wheel with string and axle. It Demonstrate the conservation of mechanical energy. On rotating the wheel by hand to the top and releasing, its potential energy will gradually convert into kinetic energy as it falls. When the wheel reaches its lowest position and starts moving up again, kinetic energy starts changing with potential energy. The wheel will stop when the total energy is lost due to friction..
