Newton's cradle

  • the cradle in motion

    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. the last sphere swings back and strikes the still nearly stationary spheres, repeating the effect in the opposite direction. the device is named after 17th-century english scientist sir isaac newton. it is also known as newton's pendulum, newton's balls, newton's rocker or executive ball clicker (since the device makes a click each time the balls collide, which they do repeatedly in a steady rhythm).[1][2]

    a five-ball newton's cradle

    a typical newton's cradle consists of a series of identically sized metal balls suspended in a metal frame so that they are just touching each other at rest. each ball is attached to the frame by two wires of equal length angled away from each other. this restricts the pendulums' movements to the same plane.
