Newton's cradle, named after Sir Isaac Newton, is a device that demonstrates conservation of momentum and energy. It is constructed from a series of pendulums butting into one another. Each pendulum is attached to a frame by two strings of equal length angled away from each other. This string arrangement restricts the pendulums' movements to the same plane. 7 1/4"Item in video is an item similar to the one for sale but may differ cosmetically.
