Newton's cradle, named after English 17th century scientist Isaac Newton, is a device that demonstrates conservation of momentum and energy using a series of swinging spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward. The device is also known as Newton's balls or Executive Ball Clicker.
