Newton’s cradle, named after Sir lsaac Newton, is a device that demonstrates conservation of momentum and energy via a
series of swinging spheres. When one on the end is lifted and released, the resulting force travels through the line and pushes
the last one upward. The device is also known as an executive ball clicker, Newton’s balls, or Newton’s pendulum construction.
