Jern OSS1851 Newton Cradle

Not only demonstrates a pendulum, but shows the laws of conservation of impulse and energy. Friction and damping effects have also been observed. Often used as toys to amuse people. If one of the balls is lifted and allowed to fall back at one end, then one will swing out the same distance at the other end. This causes the beginning of perpetual motion which dies down due to the resistance of the air and friction, an interesting process to watch. It can be an exquisite decoration for home and office.
