Newtonian Demonstrator - Newton's Cradle Manufacturer,Supplier and Exporter in India
Product Code : ILS-WAE-11717
Indian Lab Suppliers supplies the Newtonian Demonstrator - Newton's Cradle (Product ID: 11717) as part of its work and energy range. A row of suspended balls that shows how momentum and energy pass through a chain of collisions.
Quick Answer
Lift and release one ball and one ball swings out from the far end; release two and two swing out. Momentum is conserved in each collision, and because the collisions are nearly elastic, kinetic energy is almost conserved too, so the number of balls leaving matches the number arriving. Balls in contact push on each other with equal and opposite forces (Newton’s third law). The swing slowly dies away as small amounts of energy become sound and heat. The cradle measures 9 in high × 7 in wide × 9 in long and comes with an instruction sheet on the principles, use and storage.

Frequently Asked Questions
Why does the same number of balls swing out?
Momentum and kinetic energy are both (almost) conserved in the collisions.
Why does it eventually stop?
A little energy is lost as sound and heat in each collision.
How big is it?
9 in high, 7 in wide and 9 in long.
