Newtonian Demonstrator - Newton's Cradle Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12559
Jlab Export is a leading Newtonian Demonstrator - Newton's Cradle Manufacturer,and suppliers in India
Newtonian Demonstrator - Newton’s Cradle (code EL-PL-12559) is a row of steel balls hanging from a steel frame 9 in high, 7 in wide and 9 in long, in which one ball striking the others passes its motion along the line. The collisions show action and reaction, and the conservation of momentum and energy, at a glance. JLab makes the frame and balls in Ambala, India.

Reading the Collisions
Lift one end ball and let it go: it stops on impact and the ball at the far end swings out to almost the same height. Lift two and two swing out. Only this outcome conserves momentum and kinetic energy together; a single ball leaving at twice the speed would carry the right momentum but twice the energy.
Action and Reaction Along the Row
At each contact the moving ball pushes the next one, and that ball pushes back with an equal and opposite force, which is what brings the incoming ball to rest. Hard steel deforms very little, so little energy is lost at each impact, though the swing still dies away as energy goes into sound and heat with every click.
