Newton's cradle

Newton's Cradle is a device that demonstrates the principles of conservation of momentum and energy through a series of swinging spheres. It consists of a frame holding a row of identical metal balls suspended by thin wires. When one or more balls on one end are lifted and released, they strike the stationary balls in the center, transmitting the force through the line and causing the balls on the opposite end to swing outward. This classic physics demonstration visually illustrates Newton’s laws of motion and is often used as an educational tool or desk ornament.
