The physics works correctly when the tolerances are tight — cheap plastic versions dissipate too much energy to show clean elastic collisions. Conservation of momentum and kinetic energy made visible. Every physics office has one.\u003c\/p\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54140450210084,"sku":"GPP-NEWTONS-CRADLE","price":54.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/P1-6001NewtonianDemonstrator2048x2048.jpg?v=1780680473","url":"https:\/\/shop.goldenphysics.org\/products\/precision-metal-newtons-cradle-5-ball-20cm-chrome-steel","provider":"Golden Physics Project","version":"1.0","type":"link"}
