Newton's cradle demonstrates conservation of momentum and energy using a number of spheres suspended evenly. Lift and release one of the end balls, and watch. Only the end balls will lift off and swing, while the central balls remain stationary. A mesmerising effect of the Newtons Cradle. The momentum will continue, reducing until all the energy is lost at which point the balls will stop.
