Newton’s Cradle – 4 Different Styles
$10.00 – $20.00
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. Great for any desktop.
