Newton's cradle is a decorative device that illustrates the conservation of momentum and energy with suspended spheres. When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force that pushes the last sphere upward. This process is repeated, creating an interesting visual phenomenon.

This device is named after the English scientist Sir Isaac Newton and was designed by the French scientist Edme Mariotte. It is also known as Newton's pendulum, Newton's balls, Newton's clock, or ball clicker.
