Newtons Cradle
The original classic executive desk toy is a wonderful demonstration of some fundamental concepts in energy transformation and transfer, momentum, collisions and friction. Raising one ball gives it potential energy; releasing it transforms potential to kinetic energy. When it collides with the second ball and stops, its energy is transferred down through the balls until the last ball swings up and then down to start the process again. Over time, the balls lose small amounts of energy in the form of heat (due to friction between the balls).
