A Newton’s cradle 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, transmitting a force through the stationary spheres that pushes the last sphere upward.
This device is often used for demonstrations in the classroom, as well as a toy to amuse people. Newton’s Cradle was invented in 1967 by English actor Simon Prebble and named in honor of scientist and mathematician Isaac Newton, because it employs Newton’s Laws.
