Explain newtons cradle-A typical Newton's cradle consists of metal balls of identically sized in a series suspended in a metal frame ,so that they are just touching each other at rest. Each ball is gently attached to the frame by 2- wires of equal length and angled away from each other. This restricts the pendulum's movements to the same plane.
